Syntax

public Vector3 Velocity { get; set; }

Property Value

The velocity vector.

Remarks

By default, the value of this property is Vector3.Zero.

The Doppler effect value applied to a Cue is based on the relative Velocity values of the AudioEmitter and AudioListener, scaled by the DopplerScale value.

The Velocity property is used only to calculate Doppler values. It is not applied to the Position vector or otherwise used to set game state. You must set Velocity and Position each frame to maintain accurate 3D audio values in your game.
