I need to write a program to recognize the sounds of a shot. I am facing the problem of getting a spectrogram from an audio file. How important is it to implement this?

What I have tried:

I read that it is possible through the nAudio library or through FFT, but I still can't solve the problem.

This link[^] might help. It was the first result of a search on "software generate spectrogram". There are many others. It's a standard way to analyze sound, so I think you need to use them.

If you need source code, searching on "software generate spectrogram source code" turned up this post[^], which has a number of links to such software.
