2016-11-03 20:15:59

We just released Opus 1.2-alpha. It's an alpha release for the upcoming Opus 1.2. It comes with many improvements, including:

Speech quality improvements especially in the 12-20 kbit/s range
Improved VBR encoding for hybrid mode
More aggressive use of wider speech bandwidth, including fullband speech starting at 14 kbit/s
Music quality improvements in the 32-48 kbit/s range
Generic and SSE CELT optimizations
Support for directly encoding packets up to 120 ms
DTX support for CELT mode
SILK CBR improvements
Support for all of the fixes in draft-ietf-codec-opus-update-04 (the mono downmix and the folding fixes need --enable-update-draft)
Many bug fixes, including integer overflows discovered through fuzzing (no security implications)

You can get it here. Please give it a try and report any issues.

Please delete my post. It never made it to validated news and since then someone else started a 1.2-alpha thread in the Opus forum. People are commenting there, so this thread is now irrelevant.

Unfortunately, I do not patrol news submissions often enough. I could leave it in validated news and close it, directing people to the other topic for commentary.

E: Yes, everyone, continue discussing the news in the linked topic:
