What you can do here

SleepMix combines an existing library of 64 audio tracks with two live noise generators. You can mix up to six layers, adjust their volume, set a timer and save a mix for this browser. English and Chinese share the same audio and saved data. There is no account system, paid web tier or released native app offered on this site.

Audio and artwork

The audio files were migrated from the original project library without re-encoding. Recording locations, dates and equipment have not been verified, so we do not present them as original field recordings. Background artwork is generated and decorative. Track names such as 432 Hz are inherited labels, not verified measurements or therapeutic claims. White and brown noise generators synthesize sound with Web Audio.
