| Value | Meaning |
|---|---|
| dopplerTrackingDisabled0 | Disable Doppler effect simulation (default). |
| dopplerTrackingIdleStep1 | Simulate Doppler effect by tracking positions of objects that are changed in _process. Changes in the relative velocity of this Camera compared to those objects affect how Audio is perceived (changing the Audio's pitch shift). |
| dopplerTrackingPhysicsStep2 | Simulate Doppler effect by tracking positions of objects that are changed in _physics_process. Changes in the relative velocity of this Camera compared to those objects affect how Audio is perceived (changing the Audio's pitch shift). |
