Audio processing in C# or C++

I would like to create an application that uses AI techniques and allows the user to record a part of a song and then tries to find that song in a database of wav files.

I would have liked to use some already existing libraries for the audio processing part. So, could you recommend any libraries in C# which can read a wav file, get input from microphone, have some audio filters (low pass, high pass, FFT etc) and maybe have the ability to plot the audio signal as well.

I would prefer to develop in C#, but if there aren't good libraries for audio processing, I guess I could work in C++ as well. As far as I know, Mathlab already has the above mentioned functionalities, but I can't use it in my application.

If you just want to read and record audio signal, I recommend this lib

NAudio: https://naudio.codeplex.com

But if you need a signal processing support, I think this one is much better

I'm not aware of any publicly available "audio fingerprint / matching" libraries that can deal with short snippets. There's a libfooid project but I think it requires you to record the whole song. Also, the audio device interaction is not part of that library. You have to use another library for recording audio data.

Take a look at FMOD for example, not sure if it can do everything you need though.
