Yes, this seems pretty much what the author wants to implement. It's also worthwhile to have a look at the paper describing Shazam's original algorithm (http://

Yes, this seems pretty much what the author wants to implement. It's also worthwhile to have a look at the paper describing Shazam's original algorithm (http://www.ee.columbia.edu/~dpwe/papers/Wang03-shazam.pdf http://www.ee.columbia.edu/~dpwe/papers/Wang03-shazam.pdf). It's interesting (but not surprising) to see that there are many parallels among popular algorithms in computer vision and computer audio.
