What is a .opus file?
Opus is a highly efficient lossy audio codec standardized by the IETF, excelling across low-latency speech and high-quality music at a wide range of bitrates. Files typically use an Ogg container. It is the default audio codec for WebRTC and much modern streaming.
How to use this file
Use an example Opus file to test low-latency and music decoding, real-time communication pipelines, and converters that transcode between Opus and other codecs.
