The format is based on technologies and broadcast algorithms from Skype and Xiph.org (SILK and CELT codecs, respectively). OPUS is the main audio codec in Skype today. Opus' structure allows it to effectively deal with sound artifacts. For this, a multi-stage audio signal processing architecture has been proposed. The main argument that speaks in favor of using the new codec for IP telephony is low time delay. The Opus codec is used for Voice over IP (VoIP), video conferencing, in-game chat. The Opus format has been standardized by the IETF and is maintained by Xiph.Org. Audio file encoded using the Ogg Opus lossy encoding format.
