Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end embedded processors.
libopus – A reference implementation of the Opus format, the IETF standards-track successor to CELT. (Opus support is mandatory for WebRTC implementations.) libvorbis – Lossy compression, implementation of the Vorbis format; developed by Xiph.Org Foundation.
Free and open-source software portal; libavcodec is a free and open-source [4] library of codecs for encoding and decoding video and audio data. [5]libavcodec is an integral part of many open-source multimedia applications and frameworks.
Opus (RFC 6716) – based on SILK vocoder and CELT codec libopus; FFmpeg (decoding and experimental encoding) IETF Internet Draft. IPMR Speech Codec [9] - used in Spirit DSP's TeamSpirit Voice&Video Engine [10]
The Libav project was a fork of the FFmpeg project. [6] It was announced on March 13, 2011 by a group of FFmpeg developers. [7] [8] [9] The event was related to an issue in project management and different goals: FFmpeg supporters wanted to keep development velocity in favour of more features, while Libav supporters and developers wanted to improve the state of the code and take the time to ...
Compared to Vorbis, Opus can simultaneously achieve higher compression efficiency—per both Xiph.Org itself and third-party listening tests [25] [26] —and lower encode/decode latency (in most cases, low enough for real-time applications such as internet telephony or live singing, rarely possible with Vorbis). [27]
The original stand-alone CELT has been merged into Opus. Therefore, CELT as stand-alone format is now abandoned and obsolete. Development is going on only for its hybridised form as a layer of Opus, integrated with SILK. This article covers the historic, stand-alone format; for the integrated form and its evolution since the integration into ...
