MP3 Manipulation

Mar 28 2009 Posted by in multimedia | Comments Off on MP3 Manipulation

I just downloaded a file/mp3 on a friend’s computer. it’s in iTunes and I can burn it. thing is, it’s a live recording and only one file and too long to fit on a single disc. is there a way to break it up into individual tracks and not have pauses between them when playing?

Unless you’ve already got professional software, I usually recommend something called Audacity. It’s free, cross-platform, and open-source, so people have developed the shit out of it over the years. It’ll open and manipulate MP3s. There’s going to be some quality loss because the process of re-saving new MP3 files will introduce another level of compression. So, after you’ve sliced them in Audacity, I might recommend saving the new ones as stereo, 16-bit 44.1kHz AIFF files (that’s the audio CD standard) instead of MP3s, to help preserve quality. They’ll take up about 10x the storage space on your computer, but you can delete them after you burn the new CDs.

If you use iTunes for your disc burning also, it might add these AIFFs to your iTunes library by default when you drag them into the playlist, so you’ll want to delete them afterward. I think there’s a preference to turn this off as well if you like. There will be silent gaps between the songs on CD, because you’d otherwise need professional authoring software to get rid of these and conform to Red Book Audio CD standard.
