What is a OPUS file?

OPUS is a modern, highly flexible audio codec developed by the IETF and Xiph.Org Foundation. It combines the best aspects of Skype’s SILK and Xiph’s CELT codecs to deliver excellent audio quality across a wide range of bitrates and applications — from voice calls to streaming music.

OPUS is especially useful in real-time communication tools like Zoom, Discord, and WebRTC-based browsers. It adjusts dynamically to network conditions, providing smooth and clear sound even with bandwidth fluctuations.
