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.


pip install -e .


The noise color option is one of

white pink blue violet brown

the examples will use pink noise.

Play sound from speakers

python pink

save sound to disk

  1. generate raw sound file: python 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

optional high performance Python FFTW install:

sudo apt-get install libfftw3-dev

Optional PyAudio

  • Linux: apt install portaudio19-dev libjack-dev libjack0
  • Mac: brew install portaudio

and then:

pip install pyaudio

Optional Pygame

Pick one of the following methods to install pygame


simplest way for PCs, but may require compiling for ARM CPU:

pip install pygame

Linux distro

For ARM CPU, this is the best choice generally for PyGame.

apt install python-pygame

compile Pygame via pip

Usually you don't want to bother with this

apt install mercurial libflac-dev libmad0-dev libmikmod2-dev libogg-dev libportmidi-dev libsdl-image1.2-dev libsdl-mixer1.2-dev libsdl-ttf2.0-dev libsmpeg-dev libvorbis-dev libwebp-dev libwebpdemux1 sharutils libswscale-dev libavformat-dev

pip install hg+

cd /tmp

hg clone

cd /tmp/pygame

python build

python install
