Opus Interactive Audio Codec Library & Opus tools

Release date: 
Friday, 15 November, 2013



Authors/Port authors:

Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype's SILK codec and Xiph.Org's CELT codec. Opus can be adjusted seamlessly between high and low bitrates, and internally, it transitions between a linear prediction codec at lower bitrates and a transform codec at higher bitrates (as well as a hybrid for a short overlap).

Opus has a very low algorithmic delay (22.5 ms by default), which is a necessity for use as part of a low audio latency communication link, which can permit natural conversation, networked music performances, or lip sync at live events. Packages include Library for developers an tools for decoding/encoding audio files.

This software is distributed in two modes:

  • as RPM package; you can install it using your favorite rpm package manager, that will take care to download and install both the software and its prerequisites.
Choose the installation mode that you prefer. Please note that not all the versions are available in both the installation modes.
