How to normalize a signal to zero mean and unit variance?

Question

I am new to MATLAB and I am trying to built a voice morphing system using MATLAB.

So I would like to know how to normalize a signal to zero mean and unit variance us

Answer 1

You can determine the mean of the signal, and just subtract that value from all the entries. That will give you a zero mean result.

To get unit variance, determine the standard deviation of the signal, and divide all entries by that value.
