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.

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);
