# Soothing Sounds Generator

[![PyPi Download stats](http://pepy.tech/badge/soothingsounds)](http://pepy.tech/project/soothingsounds)

An acoustically pleasing Python code, targeted initially for Raspberry Pi, but should run almost anywhere.

Uses lightweight, pure Python

[SoundDevice](https://pypi.org/project/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.

```sh

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

```sh

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.)

   ```bash

   ffmpeg -f s16le -ar 16000 -ac 1 -i pink.raw pink.fla

   ```

## Notes

The core noise generation code is almost entirely from

[Python Acoustics](https://github.com/python-acoustics/python-acoustics)

### optional high performance Python FFTW install:

```sh

apt install libfftw3-dev

```
