Copyright (c) 2013, Mark VandenBrink. All rights reserved. A pure Lisp implementation for reading MPEG-4 audio and MPEG-3 audio tags and audio information. ** Mostly complete. Your mileage may vary. Most definitely, NOT portable. Heavily dependent on Clozure CCL. ** Note: There a lot of good (some great) audio file resources out there. Here are a few of them: * [l-smash](http://code.google.com/p/l-smash/) * [taglib](http://taglib.github.io/) * [mplayer](http://www.mplayerhq.hu) * [The MP4 Book](http://www.amazon.com/gp/search?index=books&linkCode=qs&keywords=0130616214) I actually didn't order this until well into writing this code. What a maroon.
