How do you plot the fft of an audio signal in matlab? Ask Question Asked 6 years, 2 months ago. Active 6 years, 1 month ago. Viewed 2k times -1 $\begingroup$ I have figured out how to get the audio sample to be read by Matlab. I have tried to use the documentation to plot the fft, but it is giving me a plot who's frequency spike is hard to read.
