since I know xiph.org adapt the tunings done by aoyumi I suspect it already has all improvements from aoTuV b5.7
Does still aoTuV perform better?
and i test vorbis 1.3.2 and i found that it have a High frequency boost very annoying at q6
Aoyumi, if you read this: please release a new aotuv vorbis, based on the CVS. Thanks a lot.
I have an iriver clix and it also has bad bass with vorbis. The iriver players decode vorbis in "low memory" mode, which causes a constant hissing/crackling noise especially noticeable in quiet moments or in music with heavy bass. It's terrible, and I was forced into buying a fuze (I'm very happy that I did tbh)...
More channels as stereo: I think, CVS is better, because CVS has channel coupling, and aotuv 5.7 not.
I think what is planned is the opposite: the next official libvorbis (1.4 version), will integrate latest AoTuV tunings.
