See what a protocol does
Carrier, beat, modulation, phase, duration, and source context are exposed instead of hidden behind a mood label.
SynSync Pro is an open-source browser audio laboratory for exploring rhythmic sound protocols. The full public library is available without an account or payment gate, with established, experimental, and exploratory material labeled in context.
Rhythmic audio can be interesting, useful, relaxing, or simply worth investigating. SynSync makes the signal, protocol settings, safety notes, and evidence boundaries visible so you can make an informed choice without a subscription funnel.
Carrier, beat, modulation, phase, duration, and source context are exposed instead of hidden behind a mood label.
Labels distinguish stronger support from experimental mechanisms and speculative exploration. The app does not promise medical outcomes.
Web Audio runs in the browser. Session settings and history use local browser storage unless you deliberately export or share them.
The full public library remains available whether or not you donate. Contributions sustain development; they do not unlock protocols.
SynSync combines familiar digital-audio techniques. The analyzer and visualizer display the generated signal; they are not EEG, neurofeedback, diagnosis, or proof of a biological effect.
Two nearby tones are delivered separately to the left and right channels. Headphones are required for the intended stereo separation.
A tone or noise layer is rhythmically amplitude-modulated. This mode can be heard through speakers or headphones.
Optional sound layers can mask harsh edges and shape the listening environment without changing the stated protocol target.
Multi-phase protocols can change carrier or beat settings over time, following the values disclosed in the phase timeline.
Start quietly, read each safety note, and stop if uncomfortable. Some users should avoid rhythmic stimulation or seek clinical advice first.
Oscilloscope, spectrum, cymatic, and WebGL views react to Web Audio analyzer data while keeping the underlying FFT and audio path intact.
A confident headline is not evidence. The useful questions are what was studied, how directly it maps to the implementation, and where uncertainty remains.
Research-backed, experimental, and exploratory protocols are presented as different categories, not blended into one promise.
Where sources are provided, follow them and assess the population, intervention, comparison, limitations, and relevance yourself.
SynSync is an audio tool, not a medical device or substitute for diagnosis, medication, therapy, or emergency care.
Tools that influence attention or experience should be inspectable, voluntary, and honest about uncertainty.
Source, signal settings, evidence labels, and safety boundaries remain available for review.
You choose the protocol, volume, duration, playback state, exports, and whether to support the project.
The release does not include third-party analytics. External sponsor, source, and crypto links load only when you choose them.
Browse the complete public catalog, including conservative calibration tools and clearly marked frontier experiments. Access does not depend on payment.
Volume checks, channel tests, and introductory sessions.
Sessions framed around wind-down, relaxation, and sleep routines.
Rhythmic audio patterns intended for attention and study contexts.
Breathing, mantra, reflection, and guided listening combinations.
Unusual-state and immersive protocols presented without equivalence-to-drug claims.
Complex modulation and layered sequences with explicit uncertainty labels.
The deployed release has no third-party analytics tag. Audio generation, playback analysis, preferences, and session history run in the browser. Network requests are still used to load the application itself, and external links contact their destinations only after you follow them.
The Web Audio graph and visualizer execute in your browser; microphone input is not required for normal playback.
Preferences and history stay in browser storage until you clear them or explicitly export a file.
This release omits analytics and advertising scripts. Hosting still necessarily receives ordinary web requests for the files it serves.
Plain-language boundary: “Local first” does not mean the website can load without contacting its host the first time. It means SynSync does not add an analytics pipeline or upload your session history during normal use.
SynSync stays open whether you contribute or not. If it is useful and you are able, a one-time or recurring contribution helps sustain development. Donations do not unlock protocols, remove limits, or create a privileged tier.
