Soothing Sounds Generator

An acoustically pleasing Python code, targeted initially for Raspberry Pi, but should run almost anywhere. Uses lightweight, pure Python SoundDevice to generate sounds. Optionally, other sound playback Python packages can be used.

I have used the outputs of this program written to SD cards, played on media players in multiple locations for a few years.

Install

pip install -e .

Usage

The noise color option is one of

white pink blue violet brown

the examples will use pink noise.

Play sound from speakers

python soothing.py pink

save sound to disk

  1. generate raw sound file: python soothing.py pink -o pink.raw
  2. convert raw to lossless FLAC (playable in almost all media players, computer, phone etc.)
    ffmpeg -f s16le -ar 16000 -ac 1 -i pink.raw pink.fla
    

Notes

The core noise generation code is almost entirely from Python Acoustics

optional high performance Python FFTW install:

apt install libfftw3-dev
