I'm trying to convolve audio signal with impulse response but every time it's giving error as "A & A must be in vector forms"
[sig1, fs] = audioread('mysong1.wav'); % import the song
t = [1:length(sig1)]/fs;
subplot(3,1,1)
plot(t, sig1) % plot the song
xlabel('t (second)')
ylabel('Relative signal strength')
title('Song')
[sig2, fs] = audioread('StNCh.wav'); % import the song
t1 = [1:length(sig2)]/fs;
subplot(3, 1, 2)
plot(t1, sig2) % plot the song
xlabel('t1 (second)')
ylabel('Relative signal strength')
title('Impulse Response')
w = conv(sig1,sig2);
t2 = 0:1:10;
subplot(3,1,3);
plot(t2,w);
xlabel('t2 (second)')
ylabel('Relative signal strength')
title('Convolved Signal')
Please help me to figure out this.

I described some reasons in the comments I posted earlier.
