I've got two MP3s. One is 5mb and one is 1.7mb, and I'd like to stick the smaller one onto the end of the larger one (I believe the programming term is "concatenate"). The point of this is that there's one section of the recording about 4 minutes long that I'd like to pull out of the (newly enlarged) file that takes place just before the larger file ends and continues into the smaller file. I have OSX Jaguar with all the normal programs like iTunes and stuff. Anybody have some ideas as to how I could accomplish this?
