abarbarian Posted September 13, 2012 Share Posted September 13, 2012 In a great victory for open standards, the Internet Engineering Task Force (IETF) has just standardized Opus as RFC 6716. Opus is the first state of the art, free audio codec to be standardized. We think this will help us achieve wider adoption than prior royalty-free codecs like Speex and Vorbis. This spells the beginning of the end for proprietary formats, and we are now working on doing the same thing for video. https://hacks.mozilla.org/2012/09/its-opus-it-rocks-and-now-its-an-audio-codec-standard/ Hurah for freedom fighters. 1 Quote Link to comment Share on other sites More sharing options...

sunrat Posted September 14, 2012 Share Posted September 14, 2012 (edited) Interesting stuff, thanks for the link. Opus is actually a development of two older codecs, SILK (low bitrate speech) and CELT (for higher quality speech and music) and switches seamlessly depending on the current usage. It is optimized for efficient transfer over the internet and the graph in that article shows good quality improvements over other codecs for low to mid bitrates. However I don't think it will replace Vorbis, AAC or FLAC for high quality* music any time soon; the perceived quality is not better for bitrates over 128 kb/s. I personally have thousands of Ogg Vorbis files mostly at Q6 (~200kb/s) and many FLAC files. And of course it is available in Debian wheezy and sid. *note I didn't include mp3 here as quality is less than the 3 mentioned formats. Edited September 14, 2012 by sunrat added high quality music qualifier 1 Quote Link to comment Share on other sites More sharing options...
