Build a simple way to blend an atmosphere for focus or rest, with no account, streamed tracks or external audio files.
The implementation
Nine procedural sound channels run through the Web Audio API. Each has its own level, while presets provide a starting point and local storage remembers the mix.
Design decisions
Sound without friction
01
Illustrated sound controls make each channel easy to recognise, with separate toggles and level sliders.
02
Presets, a master control and a sleep timer sit together in the sidebar; the mixer remains the main workspace.
03
Audio starts after a user action. The mix is saved locally, and the original application has no external resource dependencies.
The interface

Working result
A complete offline mixer with nine synthesized sounds, five presets, saved mixes and a sleep timer.
