I have a matlab question. If you don't mind I am just going to copy the post I made in to matlab.

We are analyzing sound pressure data. By recording sound from 1 source in to microphones separated at a distance of x=.25 meters. By modeling you can derive the velocity of sound from the difference of phase angles.

This works well when modeling with the Labquest device. However when using matlab I get different numbers for my phase (c).

I am using the custom equation function. (a*cos(2*pi*500*x+c)+d)
