Hi, I have just landed all of the changes on the exp_lbr_tune branch into master. I already did a lot of testing on the exp_lbr_tune branch, but considering there are more than 60 commits landing at once, it's still possible that something will break for some setups. Please give master a try and report any problems or regressions with it. Among improvements that just landed are: - SILK/hybrid CBR improvements at lower bitrates - Low bitrate hybrid mode improvements (16 - 24 kb/s) - Implementing DTX for CELT-only modes - Better coding decisions when FEC is enabled - Better bandwidth switching decisions - General quality improvements to SILK - Better music quality at low bitrate (32-48 kb/s) There's still more improvements to come and the result will be released as version 1.2 when it's ready. Cheers, Jean-Marc
