Negative gains may result in slightly lower bitrates, 711 MiB gained over a total of 27 GiB

I started experimenting a bit after Greynol said that he applies album gain prior to MP3 encoding. I did the same while transcoding my entire library to Vorbis (AoTuV) -q 5: the resulting files take 711 MiB less than their counterpart (gain unchanged), over a total of 27.2 GiB. That's a 2.56% gain; average bitrate went down from 161 kbps to 157 kbps.

Obviously, I got those results because most of my music gets negative Replaygain values. As far as I'm concerned, it's interesting because I'm pretty short on space on my Clip's 32 GB microsdhc card.

Thanks for that. Caudec in SVN can now do it too:
CODE
caudec -c ogg -q 5 -G album *.flac
