How the lab works
Generated, not streamed
Every sound here is synthesized in your browser with the Web Audio API. There are no audio files, so there are no loop seams, no buffering, and nothing to pay for.
Labeled claims
Each entry sorts what we say into mechanism, evidence, or tradition — and never dresses one up as another. Sample sizes stated, lore reported as lore.
Sound, then voice
Sound settles the room; it can't answer a busy mind. For the words half of a wind-down we point to the AYA Method — a short daily audio in your own future voice.
