Audio File Matching Program - C#

[Amin Crash]

I'm trying to write a program than can take two audio files (e.g. WAV) as inputs, compare them, and spit out a number that tells you how similar the audio files are.
If someone has done something like this, know how to go about doing it, or just have some ideas, please let me know. Anything will be greatly appreciated.

Thanks - Amin_Crash

Do you mean compare the size of audio file?
Maybe something like this?

I think it's the logic that TrackID also uses.
