Pion Opus

Pure Go implementation of the Opus Codec

This package provides a Pure Go implementation of the Opus Codec

Why Opus?

• open and royalty-free - No license fees or restrictions. Use it as you wish!
• versatile - Wide bitrate support. Can be used in constrained networks and high quality stereo.
• ubiquitous - Used in video streaming, gaming, storing music and video conferencing.

Why a Go implementation?

• empower interesting use cases - This project also exports the internals of the Encoder and Decoder. Allowing for things like analysis of a Opus bitstream without decoding the entire thing.
• learning - This project was written to be read by others. It includes excerpts and links to RFC 6716
• safety - Go provides memory safety. Avoids a class of bugs that are devastating in sensitive environments.
• maintainability - Go was designed to build simple, reliable, and efficient software.
• inspire - Go is a power language, but lacking in media libraries. We hope this project inspires the next generation to build more media libraries for Go.
