What is an OPUS file?

An OPUS file is an audio file created in the Opus format, a lossy audio format developed for Internet streaming. It uses both SILK (used by Skype) and CELT (from Xiph.Org) codecs and supports variable bit rates from 6 kb/s to 510 kb/s. OPUS files are most commonly contained using the Ogg audio container format. Thus, the files are sometimes referred to as Ogg Opus files.

The Opus codec is used for Voice over IP (VoIP), video conferencing, in-game chat. The Opus format was standardized by the IETF and is maintained by Xiph.Org.

Since the Opus codec is primarily used for streaming, files with the .opus extension that are encoded with the Opus codec are not common.
