Hello all,
I have an audio signal of a piano melody (.wav) and would like to get the frequency sequence of that to matlab command window. I don't want to plot the graph. Can anybody help me in this manner?
Thanks in advance.

Use the spectrogram function with outputs.
From the documentation:
  • [s,f,t] = spectrogram(_,fs) returns a vector of cyclical frequencies, f, expressed in terms of the sample rate, fs.
