Opus 1.1 Released

New submitter rvalles writes "Xiph.org just released a major update to their Opus audio codec. Opus 1.1 offers major improvements over last year's 1.0.2 release. Opus is a general-purpose, very flexible, open and royalty-free audio codec that offers low-latency and high quality/bitrate, incorporating technology from Skype's SILK codec and Xiph.Org's CELT codec. Its first release beat everything else last year at 64kbit/s in a listening test held at HydrogenAudio."

Compatibility

So is this backwards compatible with my existing Monster Cables or do I have to buy new ones?

Depends on what mobile device? The reference code has extensive ARM optimizations, that's in fact one of the main improvements in 1.1 And yes, it can be accelerated with a programmable DSP if present, IIRC there's some support for C55x in the same reference code.

Audio decoding is fast enough on modern ARM SoC that dedicated hardware isn't strictly needed to get good battery life.

Yeah, Monty's writing on these topics is exceptionally clear. His series on the Daala video codec introduces modern video encoding in a way that's amazingly accessible. Maybe he should write a textbook.
