Hi! I want to analyse music clip.doing STFT on this clip for pitch tracking results for time vs frequency graph. the graph should be 2D plot. how to do this in matlab? I want to find out the pitch of tones in music clip. regards kalyani

Depending on the length of the STFT, the ear's resolution of the spectrum frequency content may be higher than the bin spacing of the FFT, and the perceived pitch may be near a submultiple of the harmonics present in the spectral result, even if that frequency is not itself present. The previous time domain history also affects the current pitch. . IMHO. YMMV. -- rhn A.T nicholson d.0.t C-o-M
