you will find a MATLAB data file [url removed, login to view] containing fingerprints from 10 different songs. The information for each song is organized as a data structure, with the fields title, artist, and print (an N x 16 matrix containing the fingerprint). The fingerprints were calculated using the following algorithm:
1. Downsample audio to 22 kHz (22050 Hz).
2. For each 4096-sample ( 186 msec) frame, calculate the 128-point FFT (each FFT bin represents a
22050 ? 172 Hz band). Frames do not overlap.
