Stereo doppler effect with curve trajectory.
The doppler effect is the change of a sound's frequency experienced from an observer while moving relative to the source of the sound.
It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer.
The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession.
Synchro determines what triggers the movement.
Duration of the movement in milliseconds.
Only if the synchro=loop.
Starts moving according the drawn trajectory.
Visible only if the synchro=start button.
Clears the drawn trajectory.
Mutes the sound at the end of the movement. Only if synchro=start button.
Direction of the movement.
In the real life the more farther sources are the more hi frequencies are absorbed. This parameter set the amount of absorption according to the distance.
Amount of the Doppler effect. For hi values, hi pitch modulations.
Distance between speakers.
Volume absorption according to the observer's distance from each speaker. For low value, the volume is not affected by the distance. You can also consider this parameter as the overall size of the scene.
