Abstract

Opus [RFC6716] is a speech and audio codec developed within the IETF Internet Wideband Audio Codec working group. The codec has a very low algorithmic delay, and it is highly scalable in terms of audio bandwidth, bitrate, and complexity. Further, it provides different modes to efficiently encode speech signals as well as music signals, thus making it the codec of choice for various applications using the Internet or similar networks.
