QOATool

A C# implementation of the Quite OK Audio (QOA) format. This tool allows for encoding WAV files into QOA and decoding QOA files back into WAV.

Credits & Acknowledgements

This project is built upon the work of the QOA community:

• Format Specification: qoaformat.org
  The QOA format is a fast, lossy audio compression format with a very small reference implementation.

• Transpilation Source: github.com/pfusik/qoa-fu
  The core logic in QOA.cs is based on the transpiled source code from Piotr Fusik's qoa-fu repository.

Usage

This project is a command-line interface (CLI) tool.
