Opus Audio Codec 1.1 Officially Released

After writing last week that Opus 1.1 is nearly ready, the latest stable update to the open-source royalty-free audio codec is now available!

Opus 1.1 has been in development for many months now and serves as a very nice update over Opus 1.0. The Opus 1.1 audio codec update features improves encoding quality for variable bit-rate, automatic detection of audio or speech for better encoding decisions, improved surround, and speed improvements for all architectures.

The Opus audio handling is particularly enhanced for ARM architectures where now decoding uses 40% less CPU and encoding is down by 30%.

Many more details on Opus 1.1 are available from the mailing list announcement and this demo page.
