Hi am developing a project where I need FFT of an audio file.The audio which is stored in local storage in my system. I need frequency vs time plot. I had gone through many sites but no solution.

What I have tried:

Frequency of audio file. and after that I wanted to compare with FFT of audio file.

Solution 2

No solution? Are you serious?

I think you mean you couldn't find a solution you could copy and paste. FFT is so well documented on the web it's silly to even make the statement that you couldn't find anything on it.

Google for "FFT C#" and you'll find hundereds of thousands of samples and discussions.

Solution 1

You have to

decode the audio file
make all the necessary computations and plots

Point (1) can be difficult without using a library (however WAV file are easier). There are libraries available. You may also easily find C++ implementations of FFT.
