MATLAB program to find DFT and IDFT using matlab functions

fft on samples of an audio file in matlab. Ask Question 1. I'm trying to extract information from a sound file in order to use it in a video classification algorithm I'm working on. My problem is that I don't know how to work exactly with audio files in Matlab. Below is what I need to accomplish: open the audio file and get the sampling rate/frequency ; I need to work on a window of 2 seconds...
Y = fft(X) computes the discrete Fourier transform (DFT) of X using a fast Fourier transform (FFT) algorithm. If X is a vector, then fft(X) returns the Fourier transform of the vector. If X is a matrix, then fft(X) treats the columns of X as vectors and returns the Fourier transform of each column.

How to use the FFT (Fast Fourier Transform) in Matlab
As already mentioned, lots of MATLAB functions are written in MATLAB, so you can see the source. For performance reasons, some things are implemented in native code, or use external libraries. In the case of FFT, MATLAB uses the FFTW library, to which the source is freely available.

How To Write Fft Code In Matlab

Mathworks themselves did not write fft() in MATLAB, so you are not going to be able to get the MATLAB source for fft. You might be able to find a MATLAB source for fft, possibly if you check the MATLAB File Exchange or google for it.
