I then re-saved the mp3 to the desktop, then loaded it back into Sound Forge and the space is still gone. If I load an Mp3 into Sound Forge (which I just did), and it has 3 seconds of space before the track begins, I highlight before the signal and then backwards to delete that space. Maybe I'm misunderstanding what your goal is. The same file after has been converted to mp3 and re-imported in WaveEditor:ДЄre you sure? I've used WaveEditor, Logic, Ableton and they all do the same thing, if it's a mp3 file you're importing it'll be converted to something like a floating point in order to be used within the program, it doesn't actually stays in mp3 format, no? This is what happens to me, top file is original in. Probably a zillion others too.Are you sure?

Or I can save the file as some other format if I want. Which saves it as the file it was when loaded. I load wav or mp3 or anything into Sound Forge, trim the beginning to eliminate silence/adjust start, end, add silence when needed, normalize. My 2-track editor has always been Sound Forge.
