I downloaded OGG and FLAC plugins for Adobe Audition available here. I used the OGG encoder that comes with CDex and the FLAC encoder v1.1.2 from the FLAC site.

Here are the results (same segments of songs from the last post) including relative file sizes for Cold, Cold Heart.

Cold, Cold Heart - Norah Jones ‘Come Away with Me’

FLAC 47% of original
OGG 128kbps 8% of original
OGG 256kbps 16% of original

Sweet Child O’ Mine - Guns N’ Roses ‘Appetite for Destruction’

FLAC
OGG 128kbps
OGG 256kbps

As expected, there aren’t any noticable differences with FLAC (just as we saw with WMA lossless). OGG is an interesting one. Obviously instead of focusing on cutting the upper frequencies straight off, it seems to cut out lower volume bits and pieces.
