What's the baseline "128" of these codecs? (Score 1)

With storage capacities increasing for mini hard drives and prices falling, any compression less than 128kbps to fit more songs on your portable devices is a stopgap measure if mp3s continues to be the compression standard. Better compression obviously means getting more value out of your portable device. Since some of these codecs does a better job at compression, at what bitrate would Nero HE-AAC or Ogg compare to Lame mp3 in regard to a similar rating? Finding out those ratios should be useful to this community. I think I saw a post which said that Ogg is about 96kish in sound quality compared to mp3. Which if correct gives us 25% increased storage. Would nero be better or some other codec? Bring it down to 80kbps or so. Going after a arbitrary "64kbps" is silly. Now if they were made so we could change the firmware... oh babbbbbbby!!! more excitement for us nerds =P =)
