Bitrate verification on my set of albums:


http://www.hydrogenaudio.org/forums/index....st&p=752009

IgorC, in your set of albums, which version of aoTuV did you use to encode to vorbis? I assume that as it is your own collection, you may not always re-encode your whole collection when new versions of the encoder come out (I certainly don't). I find that aoTuV b6.02 produce files consistently larger than those produced by aotuv b5.7, which may explain why the average bitrate in the listening test is so high. I wouldn't be surprised if b5.7 produce files on average ~64-68kbps, but I would be less certain about b6.02... Then again, it could just be coincidence, that for the times I check, b6.02 tends to produce larger files...

EDIT: I just realised I'm being a bit silly, who listens to 64kbps files for pleasure anyway? You must have used the current version.

It was the last version of AoTuv 6.02 Beta.
