AudioStreamPlayer2D
===================

**Inherits:** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Plays positional sound in 2D space.

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

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

Plays audio that dampens with distance from a given position.

By default, audio is heard from the screen center. This can be changed by adding a :ref:`Listener2D<class_Listener2D>` node to the scene and enabling it by calling :ref:`Listener2D.make_current<class_Listener2D_method_make_current>` on it.

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

\ **Note:** Hiding an **AudioStreamPlayer2D** node does not disable its audio output. To temporarily disable an **AudioStreamPlayer2D**'s audio output, set :ref:`volume_db<class_AudioStreamPlayer2D_property_volume_db>` to a very low value like ``-100`` (which isn't audible to human hearing).

Signals
-------

.. _class_AudioStreamPlayer2D_signal_finished:

.. rst-class:: classref-signal

**finished** **(** **)**

Emitted when the audio stops playing.

Property Descriptions
---------------------

.. _class_AudioStreamPlayer2D_property_area_mask:

.. rst-class:: classref-property

:ref:`int<class_int>` **area_mask** = ``1``

.. rst-class:: classref-property-setget

- void **set_area_mask** **(** :ref:`int<class_int>` value **)**
- :ref:`int<class_int>` **get_area_mask** **(** **)**

Determines which :ref:`Area2D<class_Area2D>` layers affect the sound for reverb and audio bus effects. 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.

.. rst-class:: classref-property

:ref:`float<class_float>` **attenuation** = ``1.0``

Bus on which this audio is playing.

\ **Note:** When setting this property, keep in mind that no validation is performed to see if the given name matches an existing bus. This is because audio bus layouts might be loaded after this property is set. If this given name can't be resolved at runtime, it will fall back to ``"Master"``.

.. rst-class:: classref-item-separator

----

.. rst-class:: classref-property-setget

- :ref:`bool<class_bool>` **is_playing** **(** **)**

If ``true``, audio is playing.

.. rst-class:: classref-item-separator

----

.. _class_AudioStreamPlayer2D_property_stream:
