File Information

To compute STFT three windows are available in this code Rectangular, Hamming and Hanning. By default window overlapping is set by 50%. One can easily compute the STFT of sound signals.
Results are shown by 'imagesc' & 'surf'
function in single window.


This file inspired Short Time Fourier Transform.

I have a noisy signal "X", whose size is an array of "1152074 x 1". I wish calculate the "Short team fourier transform" (STFT) and implemetar in matlab. Generally, we calculate FFT, I use an algorithm that works correctly, I use a Hamming window, with NFFT = 8192 points of the signal. MAs can not do an algorithm to calculate the STFT of the signal. Can someone help me?
