downsampling a music in matlab

Hello all,

I have a .wav type music and would like to undersample it at 4kHz to view the aliasing effect. Can somebody help me please?

Thanks in advance.

doc downsample

Assuming your music is starting with a sample rate of 44.1 kHz and you are happy with a sampling rate of ~4009.09 Hz (44.1e3/11) then:

y = downsample(x, 11);
