Editing an mp3 without re-encoding it?

[Artie_Fufkin]

For example, if I wanted to take a 320kbps mp3 and edit the length, volume, etc, is there a way where I could save the edits without having to re-encode(which would reduce the quality)?
Is there a way to do this in a DAW or other software?

My significant other used to works as a signal processing engineer. I asked him about it—yes, it's technically possible, if you can find a program that lets you edit raw mp3 files on a "per frame" basis. He's never seen software that can do that, though. You might have to program it yourself.

So yes, it's possible. In the end, though, I think your life would be easier if you used a WAV instead.

I use MP3Gain, it's lossless and works on the frame basis: http://mp3gain.sourceforge.net/

mp3DirectCut.
really handy, especially for chopping up really long files.
