It could be good fiture to add beat-per-minute detection int library.
Probably, it's already done, but I cany find?
Comments: Unfortunately, NAudio does not contain a BPM detection algorithm. If a good open source one can be found and has a suitable licence, it could perhaps be ported to C#, but this is not actually a trivial task. I actually wrote about this in a [blog post](http://mark-dot-net.blogspot.co.uk/2014/01/five-audio-processing-tasks-that-are.html) recently.
