How to calculate the frequency response (spectrum) of each impulse response?

Dear all,

For an exercise we loaded two wave audio files, and plotted them:

[y1,fs1]=audioread('imp_narrow.wav'); 
[y2,fs2]=audioread('imp_wide.wav'); 

t1=0:1/fs1:(length(y1)-1)/fs1; 
t2=0:1/fs2:(length(y2)-1)/fs2;

plot(t1,y1,'color','m'); 
hold on;
plot(t2,y2,'color','g');
title('Two signals')

ylabel('Amplitude (Pa)')
xlabel('Time (sec)')

Now we need to calculate the frequency response (spectrum) of each impulse response. Can anyone help us?

Thank you in advance!

[y1,fs1]=audioread('imp_narrow.wav');

[y2,fs2]=audioread('imp_wide.wav');

t1=0:1/fs1:(length(y1)-1)/fs1;

t2=0:1/fs2:(length(y2)-1)/fs2;

plot(t1,y1,'color','m');

hold on;

plot(t2,y2,'color','g');

title('Two signals')

ylabel('Amplitude (Pa)')

xlabel('Time (sec)')
