Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)
By default, this value is 1.0.
This value determines how much to modify the calculated Doppler effect between this object and a AudioListener. Values below 1.0 scale down the Doppler effect to make it less apparent. Values above 1.0 exaggerate the Doppler effect. A value of 1.0 leaves the effect unmodified.
Note that this value modifies only the calculated Doppler between this object and a AudioListener. The calculated Doppler is a product of the relationship between AudioEmitter.Velocity and AudioListener.Velocity. If the calculation yields a result of no Doppler effect, this value has no effect.
