This is a demo version used to synthesis the sound of a sword swooshing through the air. It is a physical model based on aeroacoustic equations.. The GUI allows users to adjust the physical dimensions of the sword as well as the speed it sweeps through the air. The pre-set PGA is the synthesis of a golf swinging through the air which includes a simple additive synthesis sound of a golf ball being struck. The MLB pre-set is the synthesis of a baseball bat swing.
