Browser sound tools
The generators synthesize audio locally in your browser. The site does not request microphone permission, record you, or upload your audio. Playback uses your device’s audio capabilities.
Audio downloads
If you prepare a WAV file, your browser generates it locally using the selected sound levels, master volume, duration, and fade. No audio is sent to our server. The file remains in browser memory until it is replaced or you leave the page. If you save it, your browser and device determine its download location.
Preferences stored on this device
The site uses local storage to remember a light or dark theme, master volume, and channel levels for each generator. These values stay in your browser unless you clear site data or your browser removes them.
asmr-theme: your manually selected color theme.asmr-master: master volume.asmr-mix-*: saved channel levels for a mixer or generator.
An older version may also have saved a preference under asmr-mix. You can remove preferences using your browser’s site-data settings. Clearing them restores default settings; it does not delete any account because the site has no visitor accounts.
