Hello, I suppose this is an easy question for some. Can anyone provide me with matlab coding on finding max amplitude/max samples/average amplitudes/amplitude range from a .wav audio signal?
Thank you in advance

First you have to define what you mean by "amplitude". See another related question from earlier today: http://www.mathworks.com/matlabcentral/answers/21825-what-is-amplitudes-of-a-wav-signal

The 'native' option of wavread() will likely be desired.
Voltage calculation would be assisted by reference to http://en.wikipedia.org/wiki/Line_level#Nominal_levels
