On the same subject, I'm also seeking a program that can edit all ID-tags and read other parameters/info (like encoding, (variable) bitrates, etc...) within an MP3.
what about Sound Forge?
Didn't think of that... thanks... I'll try...

are they public? don't you have to pay for them? or was it when you wanted to do a program that encodes in mp3?
I'm not looking for the MPEG-3 encoding itself, but the fileformat of the MP3. I dunno if the MPEG-3 encoding is public or not, but the MP3 fileformat must certainly be documented very clearly somewhere... (an analogy to the GIF-fileformat as example of what I mean: I'm looking for the physical buildup of the fileformat, but not the LZW-compression which can be used by GIF)

What I want to do is to compare only the decoded audio stream.
that's quite difficult, because 2 decoded auido strams may be diferent and you'll hear the same. what you're looking for should do a frequency analisys and show results... quite complex software...
yeah... and that's exactly what I want

If what you want to compare are 2 wav (for example) files compressed in mp3 with diferent parameters (bitrate, quality, ....) maybe you can do this:
Open the files (MP3s) in soundforge and "substract" the files. You can do this inverting one file, copying it and pasting (with mixing) on the other. now listen to the result and hear the diferences yourself. (soundforge can show specographs, i think).
This way is a bit dodgy but maybe you get what you want. I'm not sure, I never did that.
Not useable for what I want right now, but I'll keep this "trick" in mind... thanks...
