- The browser demo uses repeating 30-second clips; the page distinguishes these from app playback, which it says is generated live.
Field notes
The homepage includes a playable mixer with rain, thunder, ocean, stream, fireplace, wind, birds, and brown noise, plus a visualizer playlist. Its demo clips are 30 seconds and repeat; the page says the app instead generates procedural sounds on-device and resequences recordings during playback. It lists 35 sounds in the free tier and says premium unlocks the rest, while iOS, iPad, and Android releases are marked “Coming soon.”
