System and method for creating a Doppler Effect signal in a virtual reality environment. A host produces: (1) an audio signal indicative of sound produced by a sound source, (2) a first set of signals indicative of a velocity of the sound source and an observer of the sound source, and (3) a second set of signals indicative of a position of the sound source and the observer. An interpolator interpolates the audio signal and generates an interpolation signal. A Doppler engine receives the first and second sets of signals and generates a decimation factor signal. A decimator filter, receives the interpolation signal and the decimation factor signal and generates a decimation signal. The decimation signal is a digital representation of said Doppler Effect signal and can be converted to an analog signal for broadcast to a listener.
