Abstract
The purpose of the paper is to clearly elaborate how Opus Codec can be used as Voice over IP or Unified Communication as known Opus is an Audio Codec which is royalty free and most versatile format of Audio Codec the Opus codec is used for Interactive Voice and Multimedia application, Opus codec with WEBRTC (Web Real Time Communication) is a framework based on the Chrome Web Browser the codec behavior is usually effectively utilized under testing conditions for understanding the MOS assessment in comparison to the Opus Codec.The Opus codec is generally a low latency codec used for real time interactive communication the Opus codec replaces both Vorbis and Speex for new applications.
Highlights
Opus combines the speech oriented linear predictive coding SILK algorithm with CELT algorithm for maximum efficiency in interactive communication, the Opus codec has a Hybrid mode which uses SILK and CERT for super wideband and full band audio Bandwidths in the Hybrid mode the frequency between the two cores is normally 8 KHZ
Opus codec involves performance better than 2%
The architecture of Microsoft teams involves legacy video, H.264 video tele presence, cloud phone, team’s client associated with a team combined ecosystem with MNP24 and SILK codec for teams’ conversation, teams messaging, calling and audio conferencing and video conferencing through SESSION INITIATION PROTOCOL (SIP)
Summary
Opus combines the speech oriented linear predictive coding SILK algorithm with CELT algorithm for maximum efficiency in interactive communication, the Opus codec has a Hybrid mode which uses SILK and CERT for super wideband and full band audio Bandwidths in the Hybrid mode the frequency between the two cores is normally 8 KHZ. The Opus Codec is an inherent component of WebRTC capable browser the Opus codec supports the constant variable bit rate encoding from 6 kbit/s to 510 kbit/s for frame sizes from 2.5 ms to 60 ms the Opus codec can stream up to 255 audio channels. The Opus codec can handle wide range of audio application including VOIP, VideoConferencing etc. It can scale from low bit rate narrow band to high quality stereo music [1]
