Deep Brown Noise for Focus as a MenuBar App & CLI Tool
Project description
LowHum
Deep brown noise for focus, as a macOS menu bar app. Requires macOS and Python 3.12+. Website
Brown noise is the default: cumulative-sum white noise through a 1 to 500 Hz Butterworth bandpass with a 20 Hz sub-bass highpass. Pink and white are low-passed at 8 kHz and 4 kHz so they don't hurt your ears. Files live in ~/.lowhum/ and stream through PortAudio via memory-mapped files. They're generated on first play, not at startup.
Install
uv tool install lowhum
Usage
lhm # launch the menu-bar app
lhm devices # list output devices
lhm generate # pre-generate the audio files
