How suggestions work
The planner uses your choices, device clock and records stored in this browser. Unknown context stays unknown. Nothing is sampled without an explicit action and permission. BINAURATUNE does not use your camera, location or private messages here.
This is an explainable recommendation system, not a diagnosis or a brain-state detector. A personal history changes the ranking only after enough matched blinded observations exist. Repetition without an outcome is treated as familiarity, not proof.
Compare personalizationOptional private study
Prove the fitadaptive vs static
Personalization should earn its name
At eligible moments, BINAURATUNE can conceal whether your five-minute session came from the full context policy or from a matched static policy that ignores activation, energy, room, interruption risk, history and clock. Goal, presentation, playback route, sensitivity, safety situation and dose remain matched. Record one before-and-after rating, then the policy is revealed.
Nothing is randomized when both policies would deliver the same effective session. That is not a failed test; it means the adaptation made no decision worth testing. The comparison stays on this device and makes no medical inference.

What influences what
The controls work together; they are not one long chain of effects.
Method + rhythm + carrier
Define the main sound. Timbre, shape and method-specific controls refine that route.
Hymnal or woven protocol
Uses its own tone layers instead of the ordinary method layer. Resting controls are marked in the console.
Atmosphere + optional layers
Join the active tone source. Breath tide, when enabled, modulates their shared sound bed.
Output
The combined bed passes through volume and narration ducking, dry/wet space, compression, ear-balance filters and the output ceiling.
That is the instrument route, not every imported recording or narrator. Signal diagnostics provides separate output tests.
Rhythm & carrier
Beat sets the requested rhythm from 0.5 to 100 Hz. Carrier sets the tone pitch from 60 to 1000 Hz. They are different quantities: a 200 Hz carrier with a 10 Hz binaural difference uses 195 Hz in one ear and 205 Hz in the other on the basic, unmodified route.
Delta, theta, alpha, beta and gamma are labels on the dial, not measurements of your brain. Choosing a band does not establish a psychological or health benefit.
Drive rate, where available, divides the requested rate. A 40 Hz target at one-third drive produces about 13.33 cycles per second in the sound. It does not demonstrate a 40 Hz brain response.
Blend depths work on the Blend method. Binaural depth scales the ear-to-ear difference; AM sets pulse depth; Orbit sets stereo movement; F-mod sets frequency wobble. Zero removes that component.
For example, a 10 Hz target with binaural depth at 50% produces a 5 Hz difference on the basic Blend route. Adding Orbit introduces channel mixing; it is no longer an isolated two-tone binaural signal.
Comb levels adjust individual carriers in Comb, not the Blend components. The console disables controls that the current route does not use. Read the nearby explanation rather than expecting every slider to affect every method.
Hymnal and woven protocols own their tone layers. Turn music off or end the woven protocol before returning to the ordinary method. Full reveals optional controls; it does not activate them.
Timbre changes the tone texture. Burst uses filtered noise. The Phantom and Hymnal have their own source design, so ordinary timbre controls rest there.
Pulse shape changes a compatible amplitude gate. Isochronic subharmonic drive uses its own gate, so shape choices rest until you return to Direct.
Atmosphere adds noise or a synthesized environment alongside the tones. Choose a type before adjusting its level or enabling noise pulsing. Space mixes in reverberation; it is unavailable on the ordinary Phantom route.
Hymnal replaces the method layer with generative music and its own sound controls. The beat dial still changes its beating rates. It is separate from recorded or AI-generated music in the Music workspace.
Drift varies the requested rhythm over time. Harmonic lattice adds a quieter octave layer on compatible routes. Comfort adjusts supported sound textures; it is not a loudness or hearing-safety guarantee.
Breath tide adds a slow level swell. Breath-carried depth needs a compatible Isochronic or Blend amplitude gate. Spindle loom adds sigma-rate sound packets, not measured sleep spindles.
Voice guide supplies spoken cues for supported practices. It is separate from carrier timbre and recorded narration. Photic is an optional flashing visual, not required for audio; read its warning before enabling it.
Presets load a starting configuration. Journeys change settings over a timed arc; review the arc and controls before starting. They are not wake-up alarms.
Session planner builds a session around your choices. Listening lab contains 46 activities, each with its own purpose and limits. A preference or tapping result is not a brain-state measurement.
Save an instrument setup in Presets for reuse. Saving settings is different from exporting an audio file.
Start at a low, comfortable level. Adjust one feature at a time and pause when needed. More intensity or time is not a promise of more benefit.
For binaural listening, keep channels separate. Device mono audio, spatial processing and other playback effects can change the signal after it leaves this app. The listening check cannot certify your entire physical playback chain.
Use the timer if you want an automatic fade. Save a preferred configuration instead of trying to reproduce it from memory.
Trials compares a protocol with a control using a planned sequence and ratings. Decide what outcome matters before starting, and follow the setup and listening checks.
Different conditions can still sound different. Guessing, expectations, missed sessions and ordinary day-to-day variation affect interpretation. A short run may remain inconclusive.
Personal ratings are not EEG, diagnosis or proof that a sound caused a change. Signal diagnostics answer a separate question: what audio was generated.
Pause if listening feels unpleasant. Do not use attention-demanding or sleep-oriented sessions while driving or operating equipment. The app does not diagnose or treat a condition.
A correct sound frequency does not establish brainwave entrainment, healing or a cognitive benefit. Experimental methods are ideas to investigate, not promises of latent abilities.

Enter exact HzFrequency quick picksWhy these pitches?
No carrier is proven best for each brainwave band. These are listening starting points, not prescriptions. Only the carrier changes; your rhythm, method and volume setting stay the same. Perceived loudness may change. Use a comfortable level and isolated stereo headphones for binaural listening.
340 Hz comparison: a 2025 study tested 16 and 40 Hz. Its attention finding favored 40 Hz with a 340 Hz carrier; it needs replication. 250 Hz sleep study: used a fixed left tone, not BINAURATUNE's centered pair, and did not compare carriers.
1,000 Hz AM reference: studied sinusoidal amplitude modulation at 12, 39 and 88 Hz. Other pulse shapes and rates are not that protocol. BINAURATUNE's SAM method is spatial modulation, not the sinusoidal AM abbreviation used in that paper.

Drive rate
Divide the sound's repetition rate without changing the target dial.
What the research supports
In a 23-person MEG study, 20 and 13.3 Hz tone trains elicited a 40 Hz response, but direct 40 Hz stimulation produced the largest response. Comfort was not measured. This does not establish equivalent effects at arbitrary targets or for this app's Flux and pulse envelopes.
For Isochronic, divided drive selects an asymmetric envelope so even harmonics can occur; Flux instead changes its brightness-modulation rate. Harmonics in rendered sound are not a measurement of neural entrainment. Compare how the settings feel without assuming that slower, stronger or more complex is better.
Depth
Phantom · what your ear builds

PATTERN PITCH 200 HzMODE (3,1)
Visual motion never changes the sound.
The geometry is illustrative, not a physical plate simulation or a brain-state measurement.
What the picture and readings mean
Pattern pitch follows the carrier setting, even when music or a woven protocol owns the sound. Tide drifts between neighboring pattern modes. With motion enabled, the sampled level and spectral flatness also shape the drawing.
Still view freezes animation, not audio or the readings. Changing a pattern setting can redraw the still image. Reduced-motion preferences start this view still; you can explicitly enable motion.
Live readings come from the instrument's existing analyser after its output ceiling. They update while this view is visible. Stopped, suspended or unavailable audio is not presented as a current measurement.
Approx. spectral peak estimates the strongest non-DC spectrum component, not the carrier or binaural difference. Closely spaced tones, noise and channel cancellation can make it ambiguous. RMS and sample peak are digital dBFS, not sound pressure at your ears. Values below the display floor are shown as such.
This view does not monitor every narration or imported recording. It cannot certify channel separation, entrainment, hearing safety or therapeutic effects. Use Signal diagnostics for dedicated output tests.

How pausing and editing work
Pause holds your place in Journeys and the Ladder. Their progress follows the audio clock, not time with this page open. If sequence updates are delayed by more than two seconds, playback pauses at the last applied step. Keep the page active for the smoothest timing. A playback clock is not proof of what you heard.
Volume changes keep the Journey running and preserve its fade. Editing the sound, including its method, carrier, atmosphere or Hymnal arrangement, ends the script and returns you to manual control. That interrupted sequence does not earn an endpoint record.

Why this sequence, and where the evidence ends
A 2025 sequence study found earlier changes in several self-reported mindfulness skills when novices trained focused attention before open monitoring, but only 27 people completed it, assignment was not randomized, and most final skill levels did not clearly differ by order. This single twenty-minute composition is therefore an authored hypothesis, not a reproduction of that eight-week intervention. A 2026 online comparison using semi-random sampling associated selected chills-inducing music with more self-reported chills during meditation; it did not verify physiological chills or establish clinical benefit. BINAURATUNE lets you mark a personally felt peak during this session, but does not claim its procedural score will cause one or that a button press measures physiology.
Unsaved marks remain in this page only. Export them before reloading. An export is not an automatic restore or a backup of your sitting notes. A reset applies only to this path and prevents older loaded sessions from restoring its marks.
Medito inspired the course, next-session, and local progress structure. BINAURATUNE does not copy or stream Medito recordings or scripts. Their app code is AGPL-3.0 and their original content requires a separate license, so every practice here is independently written and remains available offline inside BINAURATUNE.

Decision rule
Three complete pairs and at least a 0.5-point mean difference on a 1 to 7 scale
No conditions have been revealed. Labels stay hidden until both arms of a pair are rated.
The difference is audible, so this is concealed presentation rather than guaranteed blinding. Voice preference is measured separately in the Voice Casting Room. This tool learns a listening preference, not meditation depth, treatment response, brain state, or consciousness.

How variations work
Uses your current brief and generation settings, with the source track's duration. Influence requests similarity; it does not measure it. Your model must support the selected task.
One pre-edit original stays in this tab until the next successful generation or Forget. Download versions you want to keep. Stop waiting stops browser checks, not the service's GPU work. Sample checks do not judge musical quality.
What changed?
Compares the original and returned samples at the same positions. No time alignment, normalization or resampling. A difference is not a quality score. Listen to both versions before choosing; exact provider WAVs stay unchanged.
Protocol level & mixed export
Protocol level
Uses the console's current method, target and carrier. This is an acoustic layer, not evidence of a psychological benefit. The original master stays unchanged; mixed export creates a new WAV with the source and protocol settings recorded.
Audio facts & file management
The original WAV download is byte-for-byte what ACE-Step returned. BINAURATUNE measures its actual samples for channels, sample rate, duration, peak, RMS, DC and clipping. Tempo and key are independently estimated from the PCM, with uncertainty and metrical ambiguity shown. An estimate is not ground truth.

Portable authored contentCreator Release Studio
Package format and signature limits
Turn the latest completed Session Mastering Room WAV into one portable creator release. The download is a standard uncompressed ZIP shaped as an RFC 8493 BagIt package: exact audio, a machine-readable release record, SHA-256 manifests, and optional creator-key approval.
A signed release proves that the matching private key approved these exact bytes. It does not prove the creator's legal identity, ownership, independence, clock, or rights declaration. BINAURATUNE uses browser-native P-256 and SHA-256, but this package is not a C2PA Content Credential and has no certificate trust chain or trusted timestamp.

Complete production evaluation
The Full Listen
Compare two complete versions of the same meditation, without seeing which is which while you listen.
How comparison works
Compare two complete mastered editions of the same exact manuscript and clock. BINAURATUNE verifies the stored WAV bytes, conceals their identities, attenuates only the louder master to the quieter master's measured whole-file RMS, and requires each file to reach its natural end at normal speed before ratings unlock.
Choose two mastered versions of the same manuscript and duration.
Sample 1not heard
Sample 2not heard
Pausing and resuming is allowed. Seeking, changing playback speed, or changing the review level invalidates only the current pass. A valid earlier complete pass remains valid. Use the same headphones and system settings for both samples.
Rate the completed sample
Move every control. One number cannot stand in for the others, so BINAURATUNE keeps each production dimension separate.

Import text-only receipts from separate listeners, or include the receipt made in this tab. BINAURATUNE validates the schema, complete-playback gates, exact pair of PCM fingerprints and rating ranges, then reports counts and means without declaring a universal winner.
No review receipts are loaded in this tab.
This is a production-quality review, not a formal laboratory panel. The preparer may remember which files were selected, unsigned receipts can be copied or edited, equal RMS is not equal perceived loudness, and preference does not establish meditation efficacy, neural entrainment, therapy, healing, or access to latent abilities.

Compare voices
Narrator Endurance
Compare two 18 to 25 minute voice-only readings. Listen to each complete sample before the names are revealed.
How the comparison works
Actual WAV samples determine whole-file RMS matching by attenuation only. Both recordings must read the same manuscript.
Decision rule: use the exact same two WAV files and manuscript for every repeat. Collect at least three completed receipts across at least two UTC dates. Stop when one narrator leads the mean score by 0.50 or more and also leads direct preference. If that does not happen after five receipts across at least three dates, stop and record no practical separation.
This is a personal production screen, not a formal speech-quality panel. Equal whole-file RMS is not equal perceived loudness, the person loading the files may remember their identities, and a preferred narrator does not establish meditation efficacy, neural entrainment, therapy, healing, or a change in consciousness.

2. Describe the permission
3. Review and document
What this record does and does not prove
Bind one external agreement, license, consent record, or terms snapshot to the exact manuscript and narrator production key. BINAURATUNE measures the document bytes and records your declared scope. It never reads the document as legal text, uploads it, stores it, or decides whether the permission is legally sufficient.
Design basis: California AB 2602 requires reasonably specific intended uses for covered digital-replica provisions. The U.S. Copyright Office digital replicas report examines written authorization and license scope. C2PA UX guidance distinguishes measured assertions from creator-entered assertions and warns that a valid signature does not by itself establish trusted identity.
This is a production evidence organizer, not legal advice, a consent ceremony, a contract, a rights registry, a trusted timestamp, or verified identity. A document hash proves only which exact bytes were referenced.
Nothing is uploaded or saved. The exported dossier contains hashes and creator-entered declarations, never the evidence document, manuscript text, or source filenames.

Checking saved records.
Nothing is kept automatically. The shelf is bounded to 64 verified statements and contains public signed status records, never a private key, dossier, evidence document, or manuscript.
How authorization and status checks work
Sign one exact Narration Rights Dossier with a Creator Key, then issue a separate time-bounded status statement for that authorization. Changing the dossier, validity period, review state, or signing key creates different bytes and requires a new signature.
Design basis: W3C Data Integrity separates cryptographic authenticity from the meaning of a claim. W3C Bitstring Status List models status separately from the signed credential. C2PA security guidance distinguishes revocation, compromise, expiry, and trusted timestamps.
This local format is not W3C VC, C2PA, OCSP, a legal identity credential, or a public revocation registry. The shelf detects only newer signed statements that this device has explicitly kept. It cannot prove that no newer withdrawal exists elsewhere or that a signed review time came from a trusted clock.
Private keys stay in this tab and are never saved automatically. Create or load a Creator Key, sign an exact dossier, then issue a status statement whose next review is no more than 90 days away.
Exact-artifact production lineage
Narration Passport
Bind one directed manuscript to its measured narration, repeated endurance choice, rendered Session Master, and complete-production listening evidence. Every stage is checked from exported artifacts. A filename, provider setting, or checkbox cannot substitute for a matching content fingerprint.
Open a production stage
Load the seven text-only artifact sets. Nothing is uploaded, played, generated, or stored automatically.
A qualified passport establishes an internally consistent production chain for these exact files. It does not authenticate people, prove legal ownership, guarantee model consent, certify accessibility, or establish meditation, clinical, neural, or consciousness effects.
ACE-Step structure, BINAURATUNE authorship
Score Blueprint
Design exact musical movements before generation. Each movement gets its own clock, prompt, tempo and production contour, so a long meditation can be generated in reviewable pieces instead of one opaque request.
No model runs here. The blueprint is a deterministic production brief that can feed the browser composer or your local ACE-Step workflow.
Medito course logic, original curriculum
Path Forge
Build a private practice curriculum from BINAURATUNE's independently written techniques. The sequence begins with concrete regulation and attention skills, then widens only when the selected goal and experience level support it.
The path is stored only on this device. Completion records practice use, not improvement, meditation depth, or a brain state.
Long-form voice direction, provider neutral
Cue Director
Turn exact words into a timed cue sheet for a human narrator, VibeVoice, Voicebox, or another consented studio. Spoken text is never rewritten. Direction, speaker assignment, and silence remain separate metadata.
A cue sheet is a production plan, not generated speech. Every rendered take still needs sample checks, transcript comparison, and a complete listen.
Controlled ACE-Step iteration
Variation Lab
Create three generation briefs from one Score Blueprint movement while changing one planned musical dimension. This makes creative iteration interpretable instead of changing prompt, tempo, density, and instrumentation at once.
Design a Score Blueprint first. Generated WAVs may ignore a prompt, so the returned samples and the complete listening experience remain the source of truth.

Study design, evidence and limits
Test a visible sequence against access to the same session library. A shared study code and numbered participant slot create verifiable balanced blocks of four. The endpoint, observation window and planned sample are sealed before Schedule A is assigned. Natural session completion is recorded, while stopping early or running past the window earns no completion.
Why completion, not intention: a 2026 field study of 18,559 Spotify users found that optional meditation goal prompts did not improve population-level meditation frequency. Among people who answered, goal setting was modestly associated with more meditation days, while option order changed goals and opt-out rates. Calm adherence research likewise prespecifies objective app-use windows. Neither source establishes that a visible sequence will outperform a matched library. That is the hypothesis this tool tests.
Why the analysis follows the assignment: permuted-block methodology warns that an analysis should preserve the blocks used to assign participants. BINAURATUNE therefore reconstructs the exact distribution across all six allowed assignments in every block. As the randomization-inference framework makes explicit, the resulting p-value tests the sharp null that presentation changes nobody's completion outcome. It is not the probability that the hypothesis is true and it does not test the weaker claim that the average effect is zero.
Why enrollment now has two steps: CONSORT 2025 separates the decision to enroll from access to the assignment. First commit an eligible participant and externally recorded slot without creating Schedule A. Export that condition-free receipt to the Coordinator Desk when a separate person or device will assign the schedule. Local assignment remains available for pilots, but it does not provide independent allocation concealment.
This is a sealed local analysis charter, not public preregistration or central randomization. Fixed blocks can become predictable. Slot assignment must be recorded before Schedule A is revealed, and local assignment is not an independent central randomization service. The participant reference is hashed and the raw entry is forgotten. A verified signed packet proves only that the holder of the declared study private key signed those exact assignment bytes. It does not authenticate the person's identity, independence, clock, device security, eligibility decisions, recruitment completeness, or seed custody. Use the Coordinator Desk on a separate device controlled by someone outside recruitment when allocation concealment matters. A group result estimates completion behavior for this exact Path Forge plan. It does not establish meditation efficacy or explain why a presentation changed use.

Study design and interpretation limits
Create a public study charter before enrollment, then validate one completed study-bound Flux packet for every numbered participant slot. Group direction stays hidden until the planned slot set is complete. Participant means, not individual taps, are the unit of analysis.
A new study uses a tab-only P-256 signing authority. Export its public pin through a separate pre-enrollment channel, then export the signed charter. Participants must match both files before sealing a study plan. Legacy signed and SHA-256-only charters remain readable.
This tool can verify exact file bytes, a P-256 key signature, charter compatibility, complete numbered slots, PCM summaries and participant-level calculations. A valid signature proves only that the matching private key approved those exact bytes. It cannot prove who controls the key in the real world, unique people, consent, eligibility, independent recruitment, complete follow-up, honest slot assignment, device conditions, trusted time, or key custody. Unsigned participant packets are not identity evidence. A completed result estimates this contributed slot set under the sealed analysis, not EEG synchronization, consciousness, cognition, treatment, or a general population effect.
Separate coordinator device
Coordinator
Prepare a public study file and issue signed assignments from committed enrollment.

Build the exact practice path before creating an authority. Use a device controlled outside recruitment. Publish the public key identity before enrollment.
Issue a participant assignment

Key custody and verification limits
Create a study authority on a device controlled outside participant recruitment. The private file contains the randomization secret and signing key. Keep it off participant devices. The public file can be distributed freely. A coordinator later opens one enrollment commitment, creates the hidden arm from the private seed, and signs the exact assignment packet.
RFC 8785 canonical JSON makes the signed bytes deterministic. Web Cryptography supplies ECDSA P-256 with SHA-256 signing and verification. A valid signature detects changed packet bytes and binds them to one public key. It does not prove who held that key or whether the private file stayed private.
The private authority file is equivalent to the randomization office. Anyone who obtains it can reconstruct assignments and sign valid-looking packets. BINAURATUNE does not upload, escrow, back up, recover, or authenticate it. Use a separate coordinator device, protect the file outside BINAURATUNE, record its custody, and publish the public key identity before enrollment. This tool improves role separation but is not a substitute for an institutional randomization service.
Legacy protocol interoperability
SBaGen Bridge
Inspect a conservative subset of the original SBaGen sequence format, play the translated timing through BINAURATUNE, or export a BINAURATUNE Journey as a readable .sbg file. The receipt separates preserved protocol facts from engine-specific sound.
Sequence tools load when this card comes into view, or when you inspect a source.
This is a strict protocol translator, not an SBaGen emulator and not PCM parity. SBaGen and BINAURATUNE use different gain normalization, noise synthesis, fades, master processing, and output calibration. Unsupported syntax is refused rather than approximated silently.
Open or paste a sequence. Nothing is stored, uploaded, or played until you inspect it and press Play.
About the connected projects
Repository boundary: VibeVoice, Voicebox, Medito and ACE-Step UI remain separate projects with their own licenses and model or content terms. BINAURATUNE calls only consented local services and implements these planning and verification workflows independently.

Plans & next sessionSealed charters and progress

Your first personal Trial will seal a charter for its exact protocol. Classroom studies keep their instructor-defined plan.
Evidence Queue
Your next comparison
Suggested from progress and spacing, not interim effects. Opening setup does not allocate a condition or play audio.
Next evidence actionPrepare the first charter
A recommendation will appear from sealed progress, block closure and spacing facts only.
The queue prioritizes completion efficiency, not expected benefit. It never chooses the hidden condition. It receives no rating values, guesses, condition identities, interim contrasts, or future allocation positions. The exact protocol must still pass its normal Lab and delivery checks before allocation.
Why this recommendation?
Design basis: the ACE reporting extension requires adaptive allocation rules and their inputs to be planned and disclosed. FDA adaptive-design guidance explains why response-adaptive randomization needs careful control of bias and operating characteristics. BINAURATUNE therefore keeps the concealed arm schedule fixed and adapts only the order of unfinished protocol work.
Methods & references
Method basis: CENT 2015 asks N-of-1 trials to prespecify the primary outcome, planned measurements and stopping rules. SPENT 2019 asks protocols to state period and washout duration with a rationale when carryover is plausible. BINAURATUNE therefore seals the listener's spacing choice but does not claim that any option is biologically validated. CONSORT 2025 item 14 defines an outcome through its variable, change metric, aggregation and time point. Butcher et al. 2022 asks within-person change trials to define and justify a minimal important change. Lakens, Scheel and Isager explain why the smallest effect of interest should be fixed before results are known.
A local digest detects accidental changes but is not a public registry or tamper-proof timestamp. The composite score, secondary ratings, running journal and cross-protocol summaries remain exploratory. A charter may be retired, but its original plan and early retirement remain in the record.

Assignment recordsCompleted and missing outcomes
Every allocated position keeps its completion or missing-outcome record. Conditions and future positions stay concealed while a block is open.
No concealed positions have been allocated yet.
Confirmatory estimates still use complete blocks only. Reporting abandonment does not remove missing-data bias, but it makes that bias inspectable instead of silently treating missing outcomes as if they never existed.
Lab protocol recordsEvidence for each exact recipe
Exact Lab protocols stay separate by their SHA-256 fingerprint. A changed recipe begins a new row rather than borrowing evidence from the old one.
No qualified Lab trials yet. Qualify a fixed protocol from the Lab, then repeat both concealed conditions across several days.
The report uses deterministic randomization and bootstrap draws, adjusts protocol p-values with the Holm method, and uses early-versus-later agreement only as descriptive repeatability. It does not measure EEG, establish causation beyond the randomized contrast, prove a universal effect, or rank protocols that were not directly randomized against one another.

What the timeline records
Selections, playback requests, completion markers and detailed sitting, journey or trial records are separate events. A selection or request does not prove you heard audio. Older activity has no verified stage. The activity log retains at most 300 events; detailed records have their own histories. Overlapping entries are not a total of completed sessions. Search covers retained readable records, including older matches, without changing them. History stays on this browser origin until you export it.

Protocol rules & limitationsOptional reference
Plan before enrollment
Classroom Protocol v2 fixes one sound, one control, one primary rating outcome, a delivery route, duration, participant count and session schedule. Each four-session block contains two tested and two control sessions. Assign numbered slots without names here. The interface hides labels until ratings are saved; the public code and open source make this instructional masking, not cryptographic concealment from a technically motivated participant.
Digital checks, not identity proof
Code creation and joining each render both arms. The gate refuses more than 0.5 dB RMS difference per ear, nonfinite samples or a peak at the safety ceiling. Ear calibration must be off. A public code uses base64, not encryption or a signature. SHA-256 identities detect accidental changes and mixed protocols but do not authenticate the instructor.
Keep missing data visible
Participants complete the required playback check, run the balanced sessions and choose whether to export a minimized CSV. The pooler requires the exact v2 header, class identity, numbered positions, sealed settings, declared route and finite ratings from 1 to 10. It reconstructs assignments from the public seed. Invalid rows and duplicate positions are refused, not quietly included.
Interpret the result carefully
The planned result requires every numbered slot and complete four-session blocks without missing or refused rows. The exact blocked randomization test evaluates the sharp no-effect null, not the probability that a hypothesis is true. Neither a public code nor a browser can prove unique people, consent, independent recruitment, or protocol compliance outside the app. Personal ratings are not brain measurements.
Compare
What the leaders do better, and what nobody else does at all
Most comparison pages are advertisements with a table. This one begins with what the biggest products in this category genuinely do better than we do, because if we will not say it, you have no reason to believe the second half.
Where the big apps beat us
Recorded human content. Calm and Headspace employ studios, writers and beloved narrators; their libraries hold thousands of professionally produced hours. BINAURATUNE now offers the precise device narrator, one licensed human opening, or a measured numbered human cue pack that preserves a complete generated meditation and its timed silence. Preset-only VibeVoice and multi-engine Voicebox remain consent-gated local options. These production paths still do not replace a rights-cleared human library or its art direction. That remains a product requirement.
Native apps everywhere. They live on phones, watches and televisions with store presence and offline downloads. We are a page you can install (it works fully offline once installed), which is lighter and more private, and still not a store shelf.
Context adaptivity. Endel reads weather, heart rate, movement and location to reshape sound in real time. BINAURATUNE now makes a different trade. The Private Context Lens adds explicit room, movement and interruption facts, optional five-second local room and motion hints, and an optional standard Bluetooth heart-rate reading. Sensor hints never apply themselves, BPM remains observational, context expires on reload, and each recipe carries a complete decision receipt. The Doorway separately offers one transparent next action from a due follow-up, a plan you saved, a recently opened item, or the device hour, in that order. We still do not provide continuous weather or location adaptation. We do provide a concealed adaptive-versus-static test that can discover whether our additional context creates value rather than merely movement.
Sound aesthetics. Art-directed studios still beat synthesis for sheer beauty. BINAURATUNE now tests two complete masters through The Full Listen, including beauty, fatigue, repetition, pacing and ending quality, but a better quality gate does not create the instruments, performances and art direction that a professional source library still requires.
Where this category cannot follow
Research on binaural beats is mixed, and BINAURATUNE doesn't claim they change your brain. Listen for what you enjoy, and use the comparison tools to see what you personally prefer.
A sham you cannot tell apart. Blinded conditions are acoustically matched within half a decibel per ear, measured, re-runnable from the footer of this page. Without a matched sham, a self-test measures expectation. Nothing else in the category ships one.
Nothing to cancel. No account, no subscription, no tracker, complete export and erasure, audited. The regulator currently re-examining this category's billing practices has no business with us, because there is no bill.
Active-control discriminability · sealed listening study
Can an exact real and active-control sound be identified before outcomes, expectations or perceived benefit can influence the answer? BINAURATUNE renders the selected pair through the production master chain, balances ten A-real and ten B-real trials, and conceals every answer until the fixed twenty-pair block is complete. Each clip must finish naturally once per pair. There is no trial-by-trial feedback and no optional stopping.
Pinned binaural reference
10 Hz binaural signal at a 220 Hz carrier versus its level-matched still control.
Production PCM will be rendered and measured before allocation.

Pair 1 of 20answers remain concealed
pure guesscertain
Primary endpoint: correct identifications out of twenty, tested against chance with a two-sided exact binomial test. A non-significant result does not prove the sounds are indistinguishable. A significant result shows that this listener could discriminate this exact pair under this playback setup. It does not identify the cue, measure brain activity, or validate any psychological outcome.
Named products above are named for what they do well; their strengths are real and we recommend them for what they are best at. The comparison each reader should trust most is the one this page cannot write: run your own blinded sessions in Trials and let the inference engine tell you what your data can and cannot support.
Care and Keeping
Listening and meditation care
Sound and meditation can be uncomfortable for some people. These precautions support informed choices; they do not establish that a session is safe or suitable for everyone.
Do not use the flicker
The Lab includes an optional visual strobe. Flashing light can trigger seizures in susceptible people. As a precaution, do not use flicker if you have epilepsy, any seizure history, or a first-degree relative who does. If you have a seizure history, ask your neurologist about sound-based sessions before trying them.
The flicker stays off until you switch it on, and it never starts on its own.
Check first if
If a health condition or past experience makes you unsure whether sound, meditation or visual effects are suitable for you, ask a clinician who knows your situation.
Do not use sessions while driving, operating machinery or doing anything that requires your full attention.
Unwanted responses
If you notice headache, increased ringing, anxiety, agitation or other discomfort during a session, stop. You can choose quiet or leave the session unfinished. Adjusting settings does not establish that continuing is safe.
Stop if listening worsens your tinnitus. Seek professional advice for persistent or worsening ringing or hearing difficulty. BINAURATUNE has not been shown to treat tinnitus.
Meditation is not risk free either
Some people experience anxiety or other unwanted effects during or after meditation. You can keep your eyes open, choose quiet or stop at any time. If practice becomes distressing, stop and return your attention to your surroundings. Seek appropriate support if distress continues.
Volume
Use a low, comfortable volume and take regular breaks. Hearing risk depends on sound level and duration. This app cannot measure the level reaching your ears, and its digital limiter does not guarantee safe listening.
Everything this knows about you
Counting.
Private, unencrypted JSON, including raw stored text. Library audio and ritual manifests need separate exports.
There is no account, no server and no analytics. Settings and records live in local storage; optional mastered WAVs and Continuum rituals live separately in the private IndexedDB library. Clearing site data destroys both. Download the JSON occasionally, download each offline master you cannot replace, and export ritual manifests when their order matters. The JSON restores ordinary records into another browser, WAV files remain the portable audio copies, and manifests preserve ritual order without containing audio.

Context & further reading
What we decline to build
Eight-dimensional audio. Competitors sell this hard. We searched for a peer-reviewed literature under that name and there is none. What the term describes is slow rotational panning, which at the speeds those tracks use is ordinary perceptible movement rather than an illusion at all, and no study shows it helps relaxation or attention beyond plain novelty. That is not the same as saying it is useless: it is untested, which is a different thing from disproven. We would rather ship nothing than ship a claim we cannot support.
A personalised gamma frequency. This is the feature we most wanted to build. Everyone's gamma peak sits somewhere slightly different, modelling work suggests a two-hertz mismatch costs most of the phase locking, and we already run a validated gap-detection test whose threshold is known to correlate with individual gamma frequency. It looked like a clean line from a measurement we have to a number we could tune to. Two things stopped us. The correlation has only ever been established with EEG measured first and gap detection compared against it; nobody has published the inversion, so turning a millisecond threshold into a hertz value would be our extrapolation wearing the costume of a measurement. And the study most often cited for personalisation actually found that an auditory-derived individual frequency engaged fewer brain regions than plain 40 Hz, thirteen of sixty-eight against twenty-seven; the condition that won was task-derived and its own authors call it state-dependent rather than a stable trait. So there is no personalised gamma dial here. If we add one it will arrive as a Lab protocol wired into blinded trials, where your own data decides, rather than as a number we assert.
Closed-loop stimulation needs a measured loop. Published EEG-gated studies demonstrate stimulation that listens back: sounds are timed to measured neural phase. That differs from playing a fixed rhythm. There is no closed-loop toggle here because BINAURATUNE has no validated EEG phase-targeting pathway. Device buffering, transport delay, sound-output latency and artifacts must be measured before a future integration can claim precise timing. Overnight use also needs validated sleep-state detection in its intended setting. This remains hardware-dependent research, not a proven feature of this app.
Where a simpler answer won
Paced breathing here runs at a fixed six breaths a minute, one cycle every ten seconds, with no calibration step first. Some apps ask you to find a personal breathing rate before you begin. We kept it simple.
So the breath tide asks you nothing beforehand. You can start breathing with it straight away.
Claim
Standing
Reading
The brain's electrical activity measurably follows rhythmic sound (the auditory steady-state response)
A single session of 40 Hz stimulation improves attention or memory in healthy people
Unsupported
A 2025 study entrained gamma in real time, confirmed it on EEG, and then found no gain on perception, attention, short-term or long-term memory. Worth holding onto whenever you read a gamma claim: driving the rhythm is not the same as improving the thinking, and BINAURATUNE can generate an acoustic rhythm, but it does not measure your EEG or establish that your brain follows it.
Binaural beats raise interhemispheric EEG coherence, in the alpha band, while they play
Cymatic "healing": that sound-made patterns cure illness in body tissue
Unproven
No controlled evidence. The physics above is real. The patterns are for looking at.
Hemi-Sync produces whole-brain synchronization and trains out-of-body states
Unproven
Monroe's signal layering is a real design idea and the CIA's 1983 Gateway analysis took it seriously, but rigorous independent EEG evidence never materialized. The Ladder in our Lab is a testable rebuild.
Binaural beats entrain cortical EEG rhythms to the beat frequency
Contested
Systematic review, 2023: of 14 EEG studies, 5 were in line with entrainment, 8 contradicted it, 1 was mixed. The brainstem response is real; the cortical claim is open.
Monroe's Spatial Angle Modulation: a tone moving through a stereo arc entrains where beats cannot
Unproven
The engineering is real and public in an abandoned 2011 patent, and decoupling rate from detuning genuinely permits gamma-rate spatial rhythm. But the only published evidence is the Institute's own, and its quantum-mind rationale is speculative. Our SAM mode rebuilds the method so it can finally be tested blind.

Supported
Lutz et al., PNAS 2004: practitioners with 10,000+ hours produced sustained 25 to 42 Hz synchrony at will. The state is real and trained, not sound-induced; our gamma modes offer scaffolding, not a shortcut.

Consciousness is quantum (Orch-OR), so rhythmic sound taps quantum coherence
Speculative
Penrose and Hameroff's microtubule theory has intriguing new threads (anesthetics acting on microtubules, 2025 supportive review) and severe critics (decoherence in femtoseconds). No link from audible sound to quantum brain states exists. Randomized draws use browser cryptographic randomness. You can optionally add ANU-supplied bytes in Trials, but BINAURATUNE cannot independently verify their physical origin. Randomness provenance does not establish a consciousness effect.
Specific frequencies reliably induce sleep, meditation, or altered states in everyone
Unproven
Anecdote-rich, trial-poor. In the same lab some listeners respond strongly and others not at all; individual variation is the rule, which is why this instrument keeps handing you measurement tools.
Every row below is measured from rendered PCM samples by independent analysis (zero-crossing frequency estimation, Hann-windowed spectral estimation, envelope extraction), never from the oscillator settings that generate the signal.

Native Android receiver preview
A compiled Android debug preview now supports two strict paths. It can recreate seven protocol methods as seek-stable stereo PCM, or validate and preserve one complete BINAURATUNE mastered WAV with narration, music and cue timing. Both use Android background media controls, preserve position, and pause headphone-only audio after route loss.
Supported today in the compiled preview: Binaural, Monaural, Isochronic, SAM, Blend, Purist Comb and Nested with a sine carrier.
A Session Mastering Room WAV is independently checked from its actual samples and embedded record, copied to private app storage, then prepared without autoplay.
Unsupported stages are refused before playback instead of being silently removed.
The debug APK is reproducibly built, package-inspected and debug-signed. It is not release-signed or published. Measured PCM parity, battery, interruption and physical-device testing remain required.
Check for the preview matching this app build before downloading. Nothing starts automatically.
The check reads a small build receipt and requests file headers from this website. It does not download or install the APK, verify its signature, or test your phone. Preview files need a connection and may not be hosted with every copy of BINAURATUNE. This is a debug preview, not an app-store release.
How to move your session to Android
Choose the file that matches what you want to hear. Neither path is cloud sync, and opening a file never starts playback automatically.
Protocol file: tones only
Select Phone app below. Review every listed compatibility item. Adjust the instrument deliberately if you want to use this path; BINAURATUNE does not remove effects for you.
When the destination contract is ready, choose Export session file. This contains settings and session position, not a recording of narration or music. An active source session pauses only after the export request succeeds.
Transfer that file yourself, then open or share it with BINAURATUNE Receiver on Android. Inspect the received settings and press Apply, then Play when ready.
Mastered WAV: narration and music
In The Sitting, open the Session Mastering Room. Prepare the complete narration and music, review your permissions and listening checks, then choose Export current session WAV.
Use Send last master to Android when file sharing is supported, or transfer the unchanged exported WAV yourself. This preserves the rendered mix instead of asking the phone to recreate each effect.
Open it with BINAURATUNE Receiver. The receiver checks the audio and embedded production record, then prepares it without autoplay. A generic WAV, MP3 or editable session backup is not a Session Mastering Room WAV.
First obtain the matching debug preview above. Installation is your choice and requires a compatible Android device. Headphone-only sessions still require isolated stereo headphones. The phone must validate each file; a successful web export is not phone acceptance. Active guided sittings and blinded trials cannot be moved as a live protocol.
Move one session between devices
Export the exact requested protocol, elapsed position and remaining time as one integrity-checked file. Another browser can play the full schema today. The Android debug preview accepts only the subset it can reproduce exactly enough to test, and the destination check below will tell you when it would refuse the current setup.

These are the Credibility and Expectancy Questionnaire items used by BINAURATUNE. They record what you think about a session and how much change you expect or feel will occur. Recording expectations does not remove expectancy effects or prove that sound caused a change.

The Chordwright
Compose your own layered protocol: up to three binaural dyads sounding at once, the same machinery The Ladder climbs on. Sound it live, then take it straight into a blinded trial; sham strips every beat while keeping every tone. As Hymnal preserves the ratios between your voice rates, and the main beat dial scales them together.
The Numerosity Window
Dots flash for six tenths of a second; estimate how many you saw. Six rounds. Savants do this without counting, and magnetic suppression of the left temporal lobe briefly improved it in ordinary people. If any sound state moves your score, this window will catch it; expect noise before you trust any trend.

The Oracle Trial
Twenty draws. Before each guess, the instrument has already selected one of four symbols using browser cryptographic randomness. Chance averages five hits, not five on every run. A high score in a short run does not establish clairvoyance; repeated, prospectively planned comparisons are needed to distinguish a pattern from chance and selective reporting.

The Strange Clock
Tap with two streams of apparently random clicks. One stream contains a hidden short-range timing structure. The other uses the exact same intervals in shuffled order, preserving their mean, spread and histogram. The order is concealed until both blocks are complete.
This is a simplified replication and extension of a 2025 online tapping study. It measures whether your motor timing exploits statistical structure. It does not measure intelligence, altered consciousness or a latent ability.
Two blinded blocks, about ninety seconds total. Keep this tab visible.
The Rhythm Gate
Compare three precisely timed drum streams at 1.5, 4, and 9.5 pulses per second. Their numeric labels and order stay concealed until all three blocks are complete. The rhythms themselves remain perceptibly different, so this is condition-label blinding, not an indistinguishable sham.
A 2026 Scientific Reports study used these exact rates for ten minutes each in forty listeners. At group level, 9.5 pulses per second produced a higher altered-experience score than 1.5, while 4 was not uniquely strongest. Stronger EEG tracking at 4 Hz predicted stronger altered experience in some people. This browser version records experience and time estimation but has no EEG, so it cannot measure neural tracking or certify an altered state.
Three concealed conditions. Use a comfortable level, close your eyes if that feels safe, and keep clocks out of sight.

The Noise Ladder
First, a short adaptive staircase finds a complex tone near your own hearing threshold on this device. Then a concealed six-level comparison asks which of three intervals contains that tone. The conditions range from quiet through minimal white noise to a masker as strong as the signal.
Low-level noise can strengthen a neural response to a weak sound, but behavioral benefits are inconsistent and highly individual. This test measures detection accuracy only. It does not measure EEG, brainwave entrainment, focus, or a change in consciousness. Browser audio cannot calibrate sound pressure level, so the result is valid for this device, output level, and listening setup only.
Use headphones somewhere quiet. Set a comfortable device volume and leave it unchanged for the entire comparison.
The Flux Duel
Two concealed versions of the same harmonic texture move at exactly 2 Hz. One moves brightness while holding energy nearly steady. The other keeps brightness steady and pulses amplitude. Tap with the pulse, then rate clarity, comfort, and how well the sound could sit behind another task.
A human EEG study found that spectral flux in natural music predicted neural synchronization better than the amplitude envelope. This synthetic comparison is a new translation of that result, not a replication. It measures tapping consistency and preference. It does not measure EEG, consciousness, focus, or treatment benefit. Labels remain A and B until both blocks are complete, although the two mechanisms may still sound different.
Use a comfortable fixed device volume. Speakers or headphones both work.

Repeated-session evidence plan
Seal the attempt count, spacing, and smallest tap-lock difference worth following before the next concealed allocation. At most two attempts can enter the plan on one UTC date. Started attempts consume slots, interrupted attempts remain missing, and no effect estimate appears before the stopping boundary.
A personal plan needs no study file. A cohort contribution must be bound to a public charter and externally assigned slot before the first attempt.
No repeated-session plan is active. Ordinary duels remain descriptive practice.
One silence, two prediction structures
The Omission Gate
Two concealed streams contain the same tones, the same event times, and the same missing events. In one stream, each position in the four-tone cycle owns a stable pitch. In the other, those exact pitches are shuffled within each cycle. Press the pad whenever a tone should have arrived but did not.
Human EEG studies find larger omission responses when sound identity is predictable. Recent animal recordings also show omission responses scaling with tone probability and sequence regularity. This browser comparison asks a narrower behavioral question: does stable pitch identity improve your detection of the same silences? It measures button presses, not EEG, predictive-coding neurons, consciousness, attention benefit, or treatment.

Seal the number of attempts, spacing, and smallest difference worth detecting before the next concealed allocation. Every started attempt consumes one slot. Interrupted attempts stay visible, and BINAURATUNE withholds the planned estimate until the target is reached.
No personal evidence plan is active. Runs remain useful practice, but they are not part of a sealed repeated comparison.
Same composition, three pitch references
The Tuning Trial
Hear one deterministic composition three times in a concealed order. Every note, chord, rhythm, envelope, stereo position, duration, and measured RMS stays fixed. Only the global pitch scale changes.
The conditions are A4 = 440 Hz, A4 = 432 Hz, and C5 = 528 Hz. The last condition is equivalent to A4 = 443.99 Hz. It does not add a special 528 Hz tone. Published tuning studies are small, use different music and outcomes, and do not establish healing, DNA repair, neuroplasticity, or a universal best tuning. This 45-second-per-arm run measures your immediate preference and state only.

The Body Clock
Listen to the exact same two-minute pitched pattern twice while following a quiet visual breath guide. In one concealed arm, missing downbeats fall during paced exhalation. In the other, the identical audio timeline is replayed while the guide places those same moments during paced inhalation.
Press the large pad or Space whenever you detect a missing downbeat. The primary result is omission-detection sensitivity, hit rate minus false-alarm rate. The browser does not measure your breathing, so the comparison is meaningful only if you follow the guide comfortably. This is a behavioral pilot, not EEG, respiratory measurement, treatment, or proof that one breath phase changes consciousness.

The Sweet Spot
Five coupling levels, thirty seconds each, in random order. After each one, rate how locked-in the rhythm felt, meaning how much it pulled you rather than simply how loud it was. Theory predicts your curve peaks somewhere in the middle. If it climbs all the way to the top instead, that is a real result too, and it is yours.

The Carrier Fit
Four identity-concealed segments compare your saved carrier with a deterministic alternative while the 40 Hz pulse, waveform and production path stay fixed. Each carrier appears twice in a balanced ABBA or BAAB block. BINAURATUNE measures rendered PCM first and attenuates only the louder arm until the per-ear level difference is within 0.25 dB. Rate comfort as the primary outcome and desire to continue as a secondary outcome.
The carrier pitch is audible, so this is identity concealed rather than fully blinded. One block is descriptive. A repeatable preference needs at least three different UTC dates and may still resolve to no reliable separation. This tests listening fit, not EEG, entrainment, cognition or treatment benefit.

The Route Fit Charter
Does your measured binaural masking release predict whether a binaural or monaural 10 Hz beat feels more comfortable? BINAURATUNE freezes the hearing result before exposure, holds the 300 Hz carrier and target rate fixed, conceals route identity, and lets either route win.
BMLD is an established binaural hearing measure. It has not been validated as a predictor of binaural-beat comfort, audibility, entrainment, benefit, or treatment response. Monaural beating is physically present in each ear and will often sound more obvious, so this is identity concealed rather than fully blinded.
Measure binaural release in The Phase Key on two different UTC dates before registering this comparison.

The Metronome Inside
An objective test with no ratings in it. Tap your natural steady beat fourteen times. Listen for one minute to a blinded condition: a 2 Hz pulse, or its loudness-matched sham, chosen by hardware coin. Tap again. If rhythm entrains your motor system, your tempo drifts toward 2 Hz after the real condition and not after the sham, and the only data is your own tap timestamps. The tapping literature says motor synchronization in this range is robust; whether sixty seconds of OUR pulse leaves a measurable trace in YOU is exactly what one run cannot and many runs can answer.

Three measurements, no hidden score
The Structure Profile
Test three different parts of rhythmic behavior: whether you use serial timing structure, whether you infer a pulse that is absent from the sound, and how variable your unprompted tapping is.
BINAURATUNE reports the measurements separately. It never combines them into a talent, consciousness, intelligence, diagnosis, or latent-ability score. Relationships across tools remain exploratory until they repeat across at least eight shared UTC dates.
Serial timingnot measured
Absent beatnot measured
Free-tap variabilitynot measured
Complete each measurement on repeated days to test the planned relationships.
How the absent-beat probe works
Both concealed streams contain the same number of identical sounds, the same duration, the same level, and zero event-train energy at the 2 Hz target. One stream repeats a syncopated pattern that can imply the missing pulse. The control redraws an equal-energy pattern every four seconds. Tap the steady beat you perceive, if any. The result compares phase locking to 2 Hz, not brain activity.
The absent-beat probe has two concealed thirty-two-second streams.
Your Own Tempo
Tap the pad at whatever pace feels most natural, the speed you would walk or nod at when nobody is watching. No sound, no target, thirty seconds. Then the instrument will tell you your spontaneous tempo and offer rhythms built from it.

The Vigil
A three-minute brief Psychomotor Vigilance Test. Wait for the field to light, then press it as quickly as you can. The delay changes randomly from one to four seconds. Pressing early counts as a false start.
This follows the validated PVT-B timing and its 355 ms lapse threshold. It measures behavioral alertness, especially sensitivity to sleep loss. It does not measure intelligence or prove that a sound changed cognition. Compare runs only on the same device and browser, because screens and input hardware add latency.
Three uninterrupted minutes. Keep this tab visible.
The Smallest Silence
You will hear three bursts of noise in a row. One of them has a tiny silence cut into its middle. Say which. It gets harder each time you get it right, and easier when you miss, until it settles on the shortest gap you can reliably hear. Takes about three minutes.
The Undecided
A repeating low-high-low triplet can settle into three readings: one galloping sequence, a high line in the foreground, or a low line in the foreground. Report what you hear at the start, then press again only when it changes. Two minutes.
This is a descriptive map of one listening period. It does not measure consciousness, attention quality, personality, hearing health, or a stable trait. Speakers or headphones both work.
The Stream Atlas
Compare the same low-high-low triplet at three pitch separations. Each one-minute arm is labeled A, B, or C until every arm is complete. Report one galloping sequence, a high foreground line, or a low foreground line at the start, then press again only when your reading changes.
The order is randomized and the waveforms have identical sample RMS, timing, duration, and output processing. Pitch separation is audible, so this is not truly blinded. It tests your reports in this session, not consciousness, attention, hearing health, personality, diagnosis, or a stable trait.
Press begin when ready. Speakers or headphones both work.
The Level Turn
Four short arms test whether an upward level change reorganizes an ambiguous low-high-low sequence more than a downward change. Each arm is called A, B, C, or D until the full comparison ends. Report one galloping sequence, a high foreground line, or a low foreground line at the start, then press again only when your reading changes.
The sequence identity is concealed, not blinded, because level changes are audible. Use one comfortable device volume and do not adjust it during the comparison. The signal uses a 12 dB digital step, not a calibrated sound-pressure level. This is a behavioral translation of a published laboratory effect, not a hearing, neurological, personality, or consciousness test.
Press begin when ready. Speakers or headphones both work.
The Second Look
Register eight future dates before asking whether the Level Turn direction recurs. The app selects the first eligible complete run on each UTC date, keeps directions concealed, and stops at eight.

This prospective plan uses one fixed outcome and an exact directional sign test. It does not validate a trait or personal neural effect.
The Release
Tap with a two-pulse-per-second tone, then keep tapping when the sound stops. Four concealed endings differ only in the acoustic phase immediately before the same short safety fade.
This tests post-sound tapping behavior. It does not measure EEG, neural persistence, consciousness, meditation depth, intelligence, talent, diagnosis, treatment response, or a stable trait. Keep one comfortable volume and use the same finger for every arm.
Press begin when ready. Speakers or headphones both work.
The Missing Thread
A steady tone is briefly interrupted. Sometimes noise covers the interruption so well that hearing restores the missing sound. Decide whether the tone seemed continuous or interrupted. Twenty-four concealed trials take about four minutes.
This measures an auditory continuity illusion, not hearing loss, intelligence, suggestibility, or consciousness. Speakers work, but use the same quiet setup each time.
Press begin when the room is quiet.
The Half-Octave
Each trial plays two octave-layered tones separated by exactly half an octave. The physical relation is deliberately ambiguous. Report whether the second tone seemed higher or lower. Twelve starting pitch classes appear twice in a concealed order.
There is no correct answer. The result is your direction profile in this room, on this device, at this moment. It does not identify dialect, musical talent, personality, or neurological status.
Press begin when ready. Headphones and speakers both work.
The Coupled Voice
Wear headphones and softly whisper ta with each synthetic syllable. The pace rises from 4.3 to 4.7 syllables per second. BINAURATUNE measures the microphone recording after each run, then immediately discards the audio.
This is a browser pilot of the explicit accelerated speech-synchronization task, not the published stimulus. It reports direct, half-rate and third-rate coupling separately. It does not measure brain activity, language ability, intelligence or pathology.
Before starting Use wired or low-latency headphones in a quiet room. Keep playback comfortable. Do not turn it up to hide your own voice. Whisper rather than speaking aloud. The first thirteen-second check measures room noise, listens for headphone leakage while you stay silent, then confirms that whispered onsets are detectable. Microphone permission is used only during that check or an active run.
Calibrate this microphone, then complete two measured runs of about 80 seconds each.
The Afterimage
Ten seconds of noise with a spectral hole in it, then silence. Most people hear a faint pure tone in the silence, pitched inside the hole, made entirely by the auditory system. It is the safest way to briefly experience what a phantom sound is.
The Phase Key
Three noise bursts, one hiding a faint tone. Two rounds of the same task; in the second, the tone is secretly phase-inverted in one ear. The difference between your two thresholds is the binaural masking level difference, a real measure of the ear-timing machinery binaural beats depend on.
Playback check
The audio this instrument generates is verified at the sample level. Everything after that is outside the browser's control: Bluetooth codecs, mono accessibility settings, spatial audio, and speakers can alter or collapse the channels. This check repeats two listening tasks, preserves the stereo stimulus through the output graph, and binds the result to one declared headphone route for thirty minutes. Where the browser supports it, any observed change to the available media-device environment invalidates the receipt and stops active research sessions. This does not identify the active output device and cannot observe every output or processing change. No hardware identifier or device inventory is stored. It is an operational listening check, not a hearing test or hardware measurement. Headphones on, comfortable volume.

Coherence probe
Headphones required. Each round plays three moments of sound; in every moment both ears hear a tone at once, sometimes high, sometimes low. Count every high tone across both ears, then answer. Five rounds. Dichotic tasks like this are historically linked to interhemispheric transfer, but be honest with yourself about what a score means: with five rounds the score moves in 20-point steps, and a one-step swing is attention and practice, not rewiring. Run it before and after The Ladder, many times, over days.

The Carrier Map

Soundscape Fitting Room
Compare four production atmospheres for one real use. Every candidate comes from the same engine, level dial and output ceiling. Source names stay hidden until you finish, so a label such as rain or temple cannot cast the vote for you.
Natural sound can support positive affect and stress recovery, but preference also depends on the listener and context. This is a personal aesthetic fitting, not a treatment test or a formal ISO soundscape study.

What this comparison can establish
A result can tell you which of these two directions you preferred on this device, at this time, for this listening duration. One run cannot establish a stable trait. Repeat on different days before treating a winner as your durable profile. The one-minute option is a preview and is not an endurance test.
Why the test is concealed
Palette labels and the word customized can change expectations. Randomized Arm A and Arm B labels reduce that cue. The directions remain audibly different because those differences are the object of the test, so this is concealed presentation rather than guaranteed blinding.
