Hello, I am a MATLAB beginner and would like to make a spectrogram from a sound file but don’t know where to start. Is someone able to give me instructions, beginning with where on my computer my sound file should be saved so that MATLAB can access it?
Thank you :-)

If you have the signal processing toolbox then
doc spectrogram
will give you a spectrogram once you have loaded in your data.
