- Not to be confused with the Opus-CBCS BBS software.
Opus is a lossy audio compression format designed by the Internet Engineering Task Force (IETF) for applications requiring high-quality, low-delay audio transmission (e.g. telephony or network music performance). It incorporates technology from Skype's SILK codec and Xiph.org's CELT codec.
Opus-coded audio is usually found inside an Ogg container (where it carries the extension .opus) or in a WebM container.
