Comment (by Kamedo2):
I've encoded weeks of AACs using v4 patch, using diverse samples and
diverse bitrates and there were no problem(empty files, return with
errors, freezes).
Is 'tweaking rdlambda for VBR' ready? If not, I think I should test v4 ABR
first, because it's stable, have less artifacts in tonal samples. The
blind test will be conducted in ABC/HR methodology, and there should be
some opponents. I'm thinking of...
* current git head with no patch, abr
* v4 patch(or anything latest), abr
* fdk-aac, abr
The bitrate will be 96kbps and 128kbps.
