Sound is quite literally, one half of the movie-going experience. Without sound, you have surveillance and without the image, you have radio.  But what is sound?  You may think of it in several terms – pitch, tone… volume, but what is sound and how does it work?  In this module we’re going to look at the physics of sound – the sound wave, how it can be measured and ultimately, how it is used to create emotion through story.

 "Jason proves that top-notch production values are within the reach of anyone who has ever dreamt of making his own movie. You’ll learn far more about filmmaking with this practical, thorough and meticulously organized site than you ever will watching "Project Greenlight."
