Are you looking for a super quick way to merge multiple MP3 files into one big MP3 file? This can be done using the CAT (concatenate) command in Mac OS X. I mean, sure, you could load all the MP3’s back-to-back into a track in GarageBand and then export to a new MP3 file, but who has time for that?
I wanted to figure out how to do this so that I could quickly assemble a brief podcast. I wanted to record my one-take stream of consciousness podcast using a program called Simple Recorder, save the file, then merge it with a preexisting MP3 file that contained the canned podcast introduction. That way, I never have to open GarageBand or any other multi-track audio software. It’s quick. It’s painless. It works (usually).
I have to warn you that the method I’m about to show you is probably not the safest way to merge MP3 files. But, if the files are recorded in the same bitrate, and they are playable in iTunes, then this method should work in most cases.

By the way, you can also use the CAT command to merge other types of files. The most obvious would be text files, but you can also merge QuickTime MOV files (although I’ve never tested this).
