Create multiple tracks from single MP3 files
Authored by: Harry Tuttle on Jun 25, '04 11:21:01AM

Unfortunately a cross-fade with 0 seconds doesn't always work properly - you often end up with a slight rhythmic hiccup between the two tracks.

The problem is caused by the fact that MP3 and AAC formats only deal with complete blocks of music in their compression techniques. Most tracks do not use up the whole of the last block, so you're left with a tiny gap of sound at the end of the track. This is why you hear something like a pop sound if cross-fade is turned off. Ogg format, in contrast, doesn't suffer from this problem, but unfortunately it's not a native format for iTunes or iPod.

I had hopes that Apple Lossless format would address this issue, but it too has hiccups between tracks. Now it is possible that the reason for this isn't the Apple Lossless format itself but iTunes' playback adding in a slight delay between two files, but I expect it's the format.

I don't think it's the format. I've ripped albums to Apple Lossless and then burned to CD (with 0 track gap), and the resulting CD is seamless. I think the problem is just on playback. Apple could probably fix this by having iTunes buffer the first couple seconds of the next song to be played in a playlist.
