AudioStreamPlayer
=================

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

Plays back audio non-positionally.

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

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

Plays an audio stream non-positionally.

To play audio positionally, use :ref:`AudioStreamPlayer2D<class_AudioStreamPlayer2D>` or :ref:`AudioStreamPlayer3D<class_AudioStreamPlayer3D>` instead of **AudioStreamPlayer**.

Enumerations
------------

.. _enum_AudioStreamPlayer_MixTarget:

.. rst-class:: classref-enumeration

enum **MixTarget**:

.. _class_AudioStreamPlayer_constant_MIX_TARGET_STEREO:

.. rst-class:: classref-enumeration-constant

:ref:`MixTarget<enum_AudioStreamPlayer_MixTarget>` **MIX_TARGET_STEREO** = ``0``

The audio will be played only on the first channel.

.. _class_AudioStreamPlayer_constant_MIX_TARGET_SURROUND:

.. rst-class:: classref-enumeration-constant

:ref:`MixTarget<enum_AudioStreamPlayer_MixTarget>` **MIX_TARGET_SURROUND** = ``1``

The audio will be played on all surround channels.

.. _class_AudioStreamPlayer_constant_MIX_TARGET_CENTER:

.. rst-class:: classref-enumeration-constant

:ref:`MixTarget<enum_AudioStreamPlayer_MixTarget>` **MIX_TARGET_CENTER** = ``2``

The audio will be played on the second channel, which is usually the center.

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

.. _class_AudioStreamPlayer_property_autoplay:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **autoplay** = ``false``

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

- void **set_autoplay** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_autoplay_enabled** **(** **)**

If ``true``, audio plays when added to scene tree.

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

----

.. _class_AudioStreamPlayer_property_bus:

.. rst-class:: classref-property

:ref:`String<class_String>` **bus** = ``"Master"``

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

- void **set_bus** **(** :ref:`String<class_String>` value **)**
- :ref:`String<class_String>` **get_bus** **(** **)**

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

----

.. _class_AudioStreamPlayer_property_mix_target:

.. rst-class:: classref-property

:ref:`MixTarget<enum_AudioStreamPlayer_MixTarget>` **mix_target** = ``0``

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

- void **set_mix_target** **(** :ref:`MixTarget<enum_AudioStreamPlayer_MixTarget>` value **)**
- :ref:`MixTarget<enum_AudioStreamPlayer_MixTarget>` **get_mix_target** **(** **)**

If the audio configuration has more than two speakers, this sets the target channels. See :ref:`MixTarget<enum_AudioStreamPlayer_MixTarget>` constants.

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

----

.. _class_AudioStreamPlayer_property_pitch_scale:

.. rst-class:: classref-property

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

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

- void **set_pitch_scale** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_pitch_scale** **(** **)**

The pitch and the tempo of the audio, as a multiplier of the audio sample's sample rate.

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

----

.. _class_AudioStreamPlayer_property_playing:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **playing** = ``false``

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

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

If ``true``, audio is playing.
