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 .
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
- generate raw sound file:
python soothing.py pink -o pink.raw
- 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
apt install portaudio19-dev libjack-dev libjack0
brew install portaudio
pip install pyaudio
Pick one of the following methods to install pygame
simplest way for PCs, but may require compiling for ARM CPU:
pip install pygame
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
