An acoustically pleasing Python code, targeted initially for Raspberry Pi, but should run almost anywhere.Uses lightweight, pure PythonSoundDeviceto 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 noisecolor 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 fromPython Acoustics

apt install libfftw3-dev
