Hi, sorry to use your post..I don't know how to crete one..really sorry
I have a problem with your code:
> >> [filename, pathname] = uigetfile('*.*', 'Pick any file');
> >> [y, fs, nbits] = wavread(filename);
> >> spectrogram(y);
I make it run but says:

??? Error using ==> spectrogram at 113
X must be a vector (either row or column).
Error in ==> spec at 3
