The first release candidate to Xiph.Org's Opus 1.1 open-source audio codec is now available. Should no major issues turn up, this RC release will turn into the final version.

Opus, which since last year is an IETF standard, has been baking their 1.1 update in recent months and has been in beta since this past summer. Opus 1.1 features audio quality improvements, CPU optimizations, bug-fixes, and an experimental speech/music detector.

Opus 1.1 is big for surround sound encoding upgrades with basic bit allocation, LFE, and surround masking. Various improvements are outlined on this Xiph.Org page. Announced this morning is the Opus 1.1 release candidate and is poised to become the final 1.1 release unless any new bugs or show-stopping issues are encountered.

Details on the 1.1 RC can be found via this blog post. The Opus 1.1 RC laos has encode/decode optimizations for all CPU types -- particularly ARM with NEON optimizations -- and 48kHz 5.1 surround sound has been tuned down to 45kbps.
