Shoved up against AcoustID, I was hoping Chromaprint was an open source image fingerprinting solution with AcoustID being the audio solution. Chromaprint makes me think of image/video type terms. Anyone have any insight on how it became the name of an audio processing package?

I agree it's a slightly quirky name. The "chroma" refers to chromatography. In order to create the finger"print", an image is first extracted from the audio. An image fingerprinter would probably use many of the same techniques (e.g. fourier transform).
