AudioStreamPlayer3D
===================

**Inherits:** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Plays positional sound in 3D space.

.. rst-class:: classref-introduction-group

Description
-----------

Plays audio with positional sound effects, based on the relative position of the audio listener. Positional effects include distance attenuation, directionality, and the Doppler effect. For greater realism, a low-pass filter is applied to distant sounds. This can be disabled by setting :ref:`attenuation_filter_cutoff_hz<class_AudioStreamPlayer3D_property_attenuation_filter_cutoff_hz>` to ``20500``.

By default, audio is heard from the camera position. This can be changed by adding an :ref:`AudioListener3D<class_AudioListener3D>` node to the scene and enabling it by calling :ref:`AudioListener3D.make_current<class_AudioListener3D_method_make_current>` on it.

See also :ref:`AudioStreamPlayer<class_AudioStreamPlayer>` to play a sound non-positionally.

\ **Note:** Hiding an **AudioStreamPlayer3D** node does not disable its audio output. To temporarily disable an **AudioStreamPlayer3D**'s audio output, set :ref:`volume_db<class_AudioStreamPlayer3D_property_volume_db>` to a very low value like ``-100`` (which isn't audible to human hearing).

Areas can be used to redirect :ref:`AudioStream<class_AudioStream>`\ s so that they play in a certain audio bus. An example of how you might use this is making a "water" area so that sounds played in the water are redirected through an audio bus to make them sound like they are being played underwater.

The distance past which the sound can no longer be heard at all. Only has an effect if set to a value greater than ``0.0``. :ref:`max_distance<class_AudioStreamPlayer3D_property_max_distance>` works in tandem with :ref:`unit_size<class_AudioStreamPlayer3D_property_unit_size>`.

This can be used to prevent the **AudioStreamPlayer3D** from requiring audio mixing when the listener is far away, which saves CPU resources.
