"Mozilla and the Xiph.Org Foundation are pleased to announce the Internet Engineering Task Force (IETF) has standardized Opus as RFC 6716. Opus is the first state-of-the-art, fully Free and Open audio codec ratified by a major standards organization."

Full announcement at xiph.org/press/2012/rfc-6716

Yay!

I think they did read my email, they took off 128kbps and add 64kbps and 96kbps smile.gif

Here you can compare it with the other codecs: http://www.absoluteradio.co.uk/listen/on-other-devices.html

Just installed Firefox 15 on my Mum's PC and noticed the same thing. Absolute describe 24 kbps (mono) as Low Bitrate, 64kbps as Standard Bitrate and 96 kbps as High Bitrate, which in the context of Opus seems appropriate.

Both 64 and 96 kbps streams sound great, though I'd love to be able to listen through fb2k as well because the Classic Rock station there in particular plays a few songs with hard-panned instruments that sound like they're inside my ears on headphones so a crossfeed or speakers simulation plugin would help.

BTW, I also notice that the Examples pages of opus-codec.org now includes a cool demo of bitrate-scalability, with visual dials & readouts to show the changing bitrate, stereo mode and audio bandwidth of the seamlessly changing Opus stream (and I checked the source, it is playing Opus, and uses scripting to coordinate the readouts). I believe this was the 8-64kbps bitrate sweep demo of the Dave Matthews Band codec killer excerpt played part-way through Jean-Marc Valin's Linuxconf Australia presentation "The Swiss Army Knife of audio codecs", but now you can hear it in native Opus, being handled properly by Firefox.

I found that this played in Opera (without the required gstreamer plugins to play Opus) so I looked at the source again, and I was either mistaken, or they changed it for compatibility. The file is sweep.ogg and it's an OGG file containing Vorbis at 330kbps, clearly transcoded to very high quality Vorbis for compatibility with browsers that don't support opus yet who would like to heard the demo. This is a mere technical point, as the sound quality is bound to be essentially identical to opus directly in the 8-64kbps range. Of course, this page does not at present provide you with an opus file to test seamless bitrate and mode-changing in your opus decoder. I think there's one provided in the test vectors for that purpose.
