<<<MPEG Layer 3>>>

Or more accurately, MPEG1, Layer III. MPEG1 has been around for a long time.

You may have a different problem than you think. In oder to open a compressed audio file, Audacity has to uncompress it. And then to do effects it has to form UnDo files.

What. What happened? Where's the original question?

What he said. MP3 does add damage, however, and if it's critical that the person at the other end of the email gets perfect files, then Export As WAV. WAV files can be really large, however, and most email services have limits on how big a file you can send. WAV is officially a Windows audio format,...

<<<have imported the tracks into Audacity and "normalized". It appears to have worked (becuase the weak tracks are much stronger in terms of the wave pattern), but I can't seem to even play it without ALL of the imported tracks playing at once.>>> I don't quite understand what you did, but...

On Windows machines, all these signals have level controls in the Sound Control Panel. What happens when you change them?

How many machines are we talkin' here?
