Hi…AAC kicks the * out of both MP3 and OGG. Transparency depends on the sample but is anywhere from 64-128 kb/s. I've heard samples as low as 48 kb/s that were very good and some required 140 kb/s to sound perfect.
Opus is a new codec which unfortunately limits itself with a low delay so it loses to AAC on tonal songs but triumphs for broadband songs.
MP3 is garbage, that 140 kb/s song I mentioned earlier didn't even sound transparent at VBR 320 kb/s with MP3.
Use abchr to do your audio codec testing.
Also, wait for xHE-AAC to come out. Opus is the successor of OGG Vorbis, xHE-AAC (USAC) will be AAC's successor.

Bump.
