My trick for a moving average is to use the FIR filter with specific coefficients.

As far as playing your wav file, check out the Graphics and Sound palette.  I have little experience with them, but I know there's VIs there to play your wav file.

You need to put your Play waveform inside an event structure.  The VI will wait at the event structure until something happens such as the Value change of a boolean Play button you put on the front panel.
