I have a .wav file and the sound is for 20 seconds. I want to plot a frequency spectrum for every 2 seconds of the .wav file.
Any solutions?

See the documentation on the Signal Processing Toolbox spectrogram (link) function. It has a variety of arguments you can use that will likely give the result you want.
