In school I had a project that used edge detection to find certain patterns in audio samples. There were probably better ways to do it than looking at the spectrogram but I didn't pay enough attention in that class to know what they were. I was always curious about what else could be done with image processing algorithms and audio, it's cool to see a thread about it.
