libopus 1.2-rc1

Opus 1.2-rc1 is the first release candidate of the upcoming Opus 1.2 release. If no issues are found with it, it will soon become 1.2-final, so we encourage everyone to give it a try. Changes compared to 1.2-beta include:

• Improves quality on files with powerful tones that cause MDCT leakage
• Improves bit allocation on mode transitions (CELT to/from SILK/hybrid)
• More ARM Neon optimizations
• Fixes to the speech/music detection at the very beginning of files
• Fixes to the unit tests (fixes illegal instructions and --disable-static)
