Shall we update opus to 1.1? We currently have 1.1-beta.
Versions 1.1 released
5 December, 2013
After more than two years of development, we have released Opus 1.1.
new analysis code and tuning that significantly improves encoding
quality, especially for variable-bitrate (VBR),
automatic detection of speech or music to decide which encoding mode to use,
surround with good quality at 128 kbps for 5.1 and usable down to 48 kbps, and
speed improvements on all architectures, especially ARM, where
decoding uses around 40% less CPU and encoding uses around 30% less
These improvements are explained in more details in Monty's demo
(updated from the 1.1 beta demo).
Versions 1.1-rc3 released
3 December, 2013
This is the third and likely last release candidate for 1.1. It fixes
several bugs in the fixed-point build. Floating point is unaffected.
The code is available from the downloads page.
Versions 1.1-rc2 released
27 November, 2013
This second release candidate fixes an alignment issue on ARMv5E and
improves the Neon optimizations. Other platforms are unaffected. The
code is available from the downloads page.
Versions 1.1-rc released
26 November, 2013
We're getting closer to the final 1.1 with this new release that
further improves surround encoding quality. It also includes better
tuning of surround and stereo for lower bitrates. The complexity has
been reduced on all CPUs, but especially ARM, which now has Neon
assembly for the encoder. At last, there are a few bugfixes. The code
is available from the downloads page.
