Excerpt-based summarization of popular music

introduction
In this paper we use similarity analysis of digital audio to select excerpts as summaries of a larger work.  The excerpts are selected to maximize average similarity to the entire piece.  Please refer to the paper for more details. 

test data

Example test signal. This 100-second audio file consists of  30 seconds of a 1 kHz sine wave, 40 seconds of a 500 Hz sine wave, and 30 seconds of a 2 kHz sine wave. Because the 500 Hz portion is the longest, the ideal summary should consist primarily of the 500 Hz signal as opposed to the shorter 1 KHz and 2 KHz segments.

N.B.: These files contain nearly two minutes of highly uninteresting test tones, and there's no compelling reason for anyone to actually listen to them. We provide them for completeness, and for anyone who might care to reproduce our results using this data.
