I want to take bits of several songs I have downloaded from iTunes and concatenate them into one. I have Roxio which will allow me to do this sort of thing, but not with the songs from iTunes. If I could convert the format to something supported by Roxio, that would be ideal. I can burn a CD from iTunes then copy them back again, which works but is slow and wasteful. I got an evaluation version of Easy CD-DA extractor, but that does not recognize the iTunes files.
Does anyone know of a way either to edit the mpeg-4 format, or to convert the mpeg-4 to something editable, without going via a CD?
