Is an open source key detection tool, for DJs interested in harmonic and tonal mixing. It's intended to be very focused: no library management, no track suggestions, no media player. Just a fast, efficient workflow tool. It supports a huge range of codecs thanks to LibAV, and writes to metadata tags using TagLib.

The accuracy of the algorithm is pretty good. Here's a comparison with some other packages. I don't claim that KeyFinder is better than other key estimation software, but it shows that the algorithm is in the same league as even the best paid alternatives.

I originally developed KeyFinder in 2011 as part of my MSc in Computer Science. The algorithms, design and implementation are described in some detail in my project report, which you can download, though it's a bit heavy going.
