<P> Distance elements in these array of pairs is a monotonically-increasing set of floating point numbers measured from the location of the sound source. FrequencyCutoff elements in this list of pairs can be any positive float. While for most applications this list of values will usually be monotonically-decreasing, they do not have to be. <P> The getDistanceFilterLength method returns the length of the distance filter arrays. Arrays passed into getDistanceFilter methods should all be at least this size.</UL> </UL><P> Doppler Effect Model <P><UL> Doppler effect can be used to create a greater sense of movement of sound sources, and can help reduce front-back localization errors. The frequency of sound waves emanating from the source are raised or lowered based on the speed of the source in relation to the listener, and several AuralAttribute parameters. <P> The FrequencyScaleFactor can be used to increase or reduce the change of frequency associated with normal Doppler calculation, or to shift the pitch of the sound directly if Doppler effect is disabled. Values must be > zero for sounds to be heard. If the value is zero, sounds affected by this AuralAttribute object are paused. <P> To simulate Doppler effect, the relative velocity (change in distance in the local coordinate system between the sound source and the listener over time, in meters per second) is calculated. This calculated velocity is multipled by the given VelocityScaleFactor. Values must be >= zero. If is a scale factor value of zero is given, Doppler effect is not calculated or applied to sound.</UL></UL><P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY
