AudioEmitter.DopplerScale Property

Gets or sets a scalar applied to the level of Doppler effect calculated between this and any AudioListener.

Namespace: Microsoft.Xna.Framework.Audio
Assembly: Microsoft.Xna.Framework (in microsoft.xna.framework.dll)

public float DopplerScale { get; set; }

Property Value

The Doppler scale value.

Exception typeCondition
ArgumentOutOfRangeExceptionThe doppler scale of an audio emitter must be greater than or equal to zero.

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.
