libopus 1.3-beta
Dec 21, 2017
This Opus 1.3-beta beta release of the upcoming Opus 1.3 includes:
- Enabling by default the spec fixes in RFC 8251
- Improvements to the VAD and speech/music classification using an RNN
- Improvements to stereo speech coding at low bitrate
- Added support for ambisonics projection using mapping 3 (disabled by default)
- Fixes to the CELT PLC
Additionally, as a way to test the upcoming update to opus-tools, we’re providing Windows binaries built with 1.3-beta. These binaries are based on libopusenc, which means opusenc is finally able to make use of the Opus delayed-decision feature to make better speech/music transitions.

Win32 binaries (experimental): opus-tools-test1.zip
