File Format Description

Audio file created in the Opus format (also called "Ogg Opus"), a lossy audio format developed for Internet streaming; 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.

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

NOTE: 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.
