I've downloaded a dance combo with 19 seperate mp3's. Originally they must have been together because it's supposed to be a mix. What program can i use to join them back together so there are no gaps between the tracks? Any help would be much appreciated thanks!
Give foobar2000 a try. If you're lucky and the files are encoded with lame 3.90.x or later, playback (and decoding to single .wav file) will be gapless by default. If the encoder is something else, there are several crossfade/remove silence plugins you can use (and diskwriter to decode to .wav). If you want to keep them as mp3s, You can use mp3directcut to cut silence and join the tracks without re-encoding, but probably you won't be able to get rid of the gaps completely. (No matter what you do, make backups of the files 1st).
