• Compute & store the fingerprint
• Refactor the comparator to compare fingerprints instead of spectrograms

Subgoals:

• Creating a 2D spectrogram -Mike
• Finding the peaks -Deniz
• Computing the fingerprint hash -Both

Must be able to compare:

• file to file
• file to dir
• dir to file
• dir to dir

Interval should be computed based on the file length (so the number of samples is a power of 2)

• Check if files are mp3 (both the file extension and if it's really mp3)
• Convert MP3 to WAV

• OGG
• MP3

One possibility is to convert all file formats to wave, store those converted formats in a /tmp/ folder, and run the program on the converted wav files.

The dan program should compare the audio recordings to see whether one of them contains a segment of five seconds or more that sounds like a segment of the same length within the other
recording. If so, then the dan program should print "MATCH" to standard output, followed by a space, followed by the short name of the first file, followed by a space, followed by the short name of the second file, followed by a space, followed by the offset in seconds of the beginning of the matching segment within the first file, followed by a space, followed by the offset in seconds of the beginning of the matching segment within the second file, followed by a newline. Only one such line should be produced for each pair of audio recordings.

If at any point two segments don't match, quit. Matches will (probably?) be all or nothing for assignment 4.
