Code looks great, but this library requires some sort of frontend to be functional, not to mention that the code hasn't updated in years (probably not since Gian-Carlo's initial release).

audfprint comes with a functional commandline interface for managing such a database, at least in basic form. While I get that this sort of thing can conveniently be written in Matlab, that choice won't help with adoption of the tool. I hardly know of anyone with a Matlab runtime ready to go for random tools.

So torn between a (possibly outdated) library, and code written for an, let's say unusual, runtime, neither of these two really appeal if I wanted to build a de-duplicating audio library.
