This is a simple acoustic beam steering simulation built in Processing/Java. The simulation has physical correspondence; it runs at 1/2000th realtime and at a scale of 10 pixels = 1 meter. The array size is fixed at 2.5 meters (25 pixels tall), positioned at the left edge of the display region. More at HRTF and Beam Steering project page.
