MATLAB: Playing an under-sampled .wav music in matlab

Question

Hello all,

I've undersampled a .wav music and would like to play it in Matlab to hear the effect of aliasing. Can you please guide me?

Thank you.

Answer 1

You can use wavread to read in your wave file and then use audioplayer to play it. Or if you have the downsampled music already in a variable, you can directly pass it to audioplayer. See the following documentation and there is an example

alternatively, you can launch the doc from MATLAB

doc audioplayer
doc wavread
