Overrides the location sounds are heard from. Once added to the scene tree and enabled using [method make_current], this node will override the location sounds are heard from. This can be used to listen from a location different from the [Camera3D]. Disables the listener to use the current camera's listener instead. Returns the listener's global orthonormalized [Transform3D]. Returns [code]true[/code] if the listener was made current using [method make_current], [code]false[/code] otherwise. [b]Note:[/b] There may be more than one AudioListener3D marked as "current" in the scene tree, but only the one that was made current last will be used. Enables the listener. This will override the current camera's listener. If not [constant DOPPLER_TRACKING_DISABLED], this listener will simulate the [url=https://en.wikipedia.org/wiki/Doppler_effect]Doppler effect[/url] for objects changed in particular [code]_process[/code] methods. [b]Note:[/b] The Doppler effect will only be heard on [AudioStreamPlayer3D]s if [member AudioStreamPlayer3D.doppler_tracking] is not set to [constant AudioStreamPlayer3D.DOPPLER_TRACKING_DISABLED]. Disables [url=https://en.wikipedia.org/wiki/Doppler_effect]Doppler effect[/url] simulation (default). Simulate [url=https://en.wikipedia.org/wiki/Doppler_effect]Doppler effect[/url] by tracking positions of objects that are changed in [code]_process[/code]. Changes in the relative velocity of this listener compared to those objects affect how audio is perceived (changing the audio's [member AudioStreamPlayer3D.pitch_scale]). Simulate [url=https://en.wikipedia.org/wiki/Doppler_effect]Doppler effect[/url] by tracking positions of objects that are changed in [code]_physics_process[/code]. Changes in the relative velocity of this listener compared to those objects affect how audio is perceived (changing the audio's [member AudioStreamPlayer3D.pitch_scale]).
