matlab - Demodulation and recovering bits FM

Question

I'm looking for help with one exercise. Firstly I was supposed to download a FM modulated signal.

[y,fs] = audioread('signal.wav');

And then I have to "recover bits that are coded by different frequency values(states)". How can I do that? I was trying demodulation:

fc=1000;
z=demod(y,fc,fs,'fm');

But I don't know what to do next. Can you help me?
