WebOpus is a relatively new audio codec that was created through a joint effort between several organizations based on two previously available codecs: SILK from Skype, and CELT from Xiph.org. Opus has seen a lot of press lately due to its receiving a newly IETF approved standard in RFC 6716. WebJul 27, 2016 · Opus is an interactive speech and audio codec. It is designed to handle a wide range of interactive audio applications, which includes Voice over IP, videoconferencing, in-game chat, and even live distributed music performances. It scales from low bitrate narrowband speech at 6 kbit/s to very high quality stereo music at 510 kbit/s.

"WebThe voice mode of the Opus audio coder can compress wide-band speech at bit rates ranging from 6 kb/s to 40 kb/s. How-ever, Opus is at its core a waveform matching coder, and as the rate drops below 10 kb/s, quality degrades quickly. As the rate reduces even further, parametric coders tend to perform better than waveform coders. " - Opus codec quality improvement
