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.

pip install -e .

The noise color option is one of

white pink blue violet brown

the examples will use pink noise.

python soothing.py pink

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

The core noise generation code is almost entirely from Python Acoustics

apt install libfftw3-dev
