Phase Vocoder Technology for the Simulation of Engine Sound

For a driving simulator which should be an exact replica of a certain vehicle, an accurate sound model is of extreme importance. The most games select between three or more prerecorded engine sounds, depending on the engine speed. Other methods use linear interpolation between engine sounds for a more accurate approximation, but this is still not ideal. By using vocoders, a technique used for the manipulation of voice, a much higher level of accuracy and realism can be obtained. This article proposes the use of vocoders for the modeling of engine sound for driving simulation and computer driving games.
