You may need to throw together your own custom class for that. I looked around and couldn't find any libraries specifically for that purpose, but creating your own shouldn't be to hard.

Here is a list of the frequencies for different musical notes: http://www.seventhstring.com/resources/notefrequencies.html

You could create a class that uses these numbers and compares the sound to each frequency to see which it is.

Turning the wav file input to frequencies will require a FFT. Here is a link to a question that explains how to do just that. Wav File As Frequency Image
