How to make the spectrogram function output the actual frequencies instead of the normalized ones?

This program performs a frequency sweep on a song and prints out the spectrogram, however, it displays normalized frequencies and I was wondering if there's any way to get it to display the actual frequencies instead. Here's the code:

wave_file = 'Here_Comes_a_Special_boy.wav';
[abc,fs] = audioread(wave_file);

noverlap = [];
spectrogram(abc,256,noverlap,[]);
