Summary0021904: AAC encoder in 3.0.11 does not work as expected
Description2 serious issues:
1) setting VBR 100% should create ~210kbps file, but it creates ~135kbps
2) encoding to raw AAC stopped working

Fixed in codec pack 3.0.12. 1) was caused by different handling of bitrate values by new version of AAC encoder, 2) was regression caused by previous changes.

We also use updated and a lot faster version of AAC encoder now. I added support for higher bitrates, now average bitrate can be set up to 512kbps and quality percent can go up to 1000 now. 100 % should be similar like before, only now users can go up a lot more, if needed for some reason.
Note, that bitrate for VBR is highly dependent on complexity of original audio, from my tests quality "100 %" can be 194kbps for one file, but also 260kbps or even more for another.
