This Opus 1.1.1 release brings many optimizations to the encoder
and decoder, including:
* x86 SSE, SSE2 and SSE4.1 intrinsics optimizations with run-time
CPU detection contributed by Cisco Systems,
* MIPS intrinsics optimizations contributed by Imagination
Technologies,
* ARM Neon optimizations contributed by Linaro and ARM,
* many architecture-independent optimizations and memory footprint
reductions that should improve performance on all platforms,
and
* several minor bug fixes.
The quality of the encoder should be mostly unchanged compared to
version 1.1.
and update to 1.1
Changelog:
Opus 1.1 includes:
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 CPU.
