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.
How to open OPUS files
OPUS files are supported by VLC, Foobar2000, Audacity (with plugin), and mobile apps like Opus Player. WebRTC-compatible browsers also support this format.
To convert OPUS to more widely used formats like MP3 or AAC, use AnyConv online for a fast result.
