If by the plot does not look "good" you mean it is split and spread out its because the FFT is not centered. Use abs(fftshift(fft(x))) instead to get a centered plot.
*Edit: the order which you use fftshift does matter, it should be used after you take the fft.
I was suspecting that the size of the file was not related to the actual content of the data.
In that case, is the process I am using to compress the data the correct method? And in order to find the relative compression should I be comparing the energy of the original signal to my compressed...
Hello all,
I had some questions regarding audio compression (bit reduction) using the Short Time Fourier Transform.
I am trying to implement this in MATLAB.
For the STFT, my method has been as follows:
1. Window the desired signal by multiplying the signal with a rectangle of desired length...
