In all of those, it sounds great - I can't tell the MP4 apart from the MP3 for the same song. Playing to Quicktime yields the opposite: it sounds horrible, as if it was a 64kbps MP3.
Usually, I can't tell the difference between 128kbps MP3s and higher quality, but this has be baffled. I can't figure out if the MP3 or AAC/MP4 is better. A couple of friends have tried, and none can tell the difference either.So, the question comes out: which is better: AAC/MP4 or MP3, or are they the same?
It also reports (in VLC, on the Advanced information tab) the bitrate to be 1411 kb/s, but then on the Statistics tab it shows 64 kb/s. Is there any more information I could extract from these files?
In my opinion, 128 kbps MP3 file (lame-encoded) sounds better than 64 kbps AAC.
This means that the compressed file is 64 kb/s but it decodes to 1411 kb/s.

Does that mean that the 64kbps stream contains 1411 kb/s worth of information? That seems like an uncompressed WAV or lossless codec. If it makes a difference, VLC properly reports a 128kb/s MP3 as 128 kb/s on both screens.-gotPSP
