== Description ==

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.
