Get the frequency sequence of an audio file

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.
