An illustration of the Doppler Effect and how relative motion affects the perceived frequency. Various different flypast cases are animated and put together with the simulated sound. Animations coded using Visual Basic .NET, the sprites were Microsoft clip art ;-) and the sound was coded and output using LabVIEW 2010.
