I've tested the same files as before the release of Opus 1.2 (including the
track "Nick Warren - Devil's Elbow" I used for this mailing list to
demonstrate the issue this summer) and the problem with speech / music
classification has gone for both 32 kbps and 48 kbps. It's no longer
necessary to use the --set-ctl 4024=3002 encoding parameter for bitrates
lower than about 64 kbps. Thanks everyone for their good work!

I just released Opus 1.3-beta. This is a beta release towards the
upcoming Opus 1.3. Changes include:
- The spec fixes in RFC 8251 are now enabled by default
- 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
- 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.
Please report any issues. Have fun!
