Noism
Nature sound mixer for focus and sleep — for hackers and deep-focus work.
Noism plays offline ambiences on Android: rain, ocean, wind, birdsong, frogs, and generated stereo noise. Every loop is crafted to be seamless — no gaps, no interruptions — and everything works fully offline with a foreground playback service for stable, screen-off listening.
The Android download is a compressed .7z archive — extract the APK before installing.

Android + Linux CLI
Noism ships as an Android app with the full bundled ambience library, and as a Linux
terminal CLI with a live TUI. The CLI package contains the scripts; generated noise works
with ffmpeg out of the box, and you can drop your own OGG files into its
sounds/ folder for rain, ocean, and wind. It needs Bash, ffmpeg, ffprobe, and
ffplay.
What it does
- Bundled offline ambiences: rain, ocean, wind, birdsong, frogs, and nighttime ambience.
- Generated stereo-wide noise: white, pink, brown, mixed, neutral, and soft — synthesized at runtime with independent left and right channels.
- Seamless loop playback — no gaps, no clicks.
- Mixer board for layering sounds together.
- Category filter and a simple track list.
- Foreground playback service for long, stable screen-off listening.
- Companion Linux CLI with a live terminal UI, loop cache, and MPRIS / media-key helpers.
