straw-codec 0.2

Lossless codec for multichannel audio

Straw

Straw is a lossless audio codec intended for efficiently storing multichannel audio

Current state

This project is still a work in progress and as such is not yet ready to be used safely.

The interface and imports are subject to frequent change.

The use of this library in its current form is strongly discouraged!

Installation

Create a Python virtual environment, activate it and install the dependencies

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Usage

Library

The library usage is analogous to soundfile:

import straw

data, sample_rate = straw.read("existing_file.straw")
straw.write("new_file.straw", data, sample_rate)

Standalone encoder/decoder

First activate the virtual environment:

source venv/bin/activate
export PYTHONPATH=$PYTHONPATH:src

Encoding:

python3 main.py -i /path/to/input.wav -o /path/to/output.straw

Decoding:

python3 main.py -d -i /path/to/input.straw -o /path/to/output.wav
