MATLAB 'spectrogram' params

Question

I am a beginner in MATLAB and I should perform a spectral analysis of an EEG signal drawing the graphs of power spectral density and spectrogram. My signal is 10 se

Answer 1

For the last parameter fs, that is the frequency rate of the raw signal, in your case X, when you extract X from audio data using function

[X,fs]=audioread('song.mp3')

You may get fs from it.
