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.

Unlike previous audio codecs, which have typically focused on a narrow
set of applications (either voice or music, in a narrow range of
bitrates, for either real-time or storage applications), Opus is
highly flexible. It can adaptively switch among:
Bitrates from 6 kb/s to 512 kb/s
Voice and music
Mono and stereo
Narrowband (8 kHz) to Fullband (48 kHz)
Frame sizes from 2.5 ms to 60 ms
Most importantly, it can adapt seamlessly within these operating
points. Doing all of this with proprietary codecs would require at
least six different codecs. Opus replaces all of them, with better
quality.
