AudioStreamGeneratorPlayback
============================

**Inherits:** :ref:`AudioStreamPlaybackResampled<class_AudioStreamPlaybackResampled>` **<** :ref:`AudioStreamPlayback<class_AudioStreamPlayback>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

Plays back audio generated using :ref:`AudioStreamGenerator<class_AudioStreamGenerator>`.

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

This class is meant to be used with :ref:`AudioStreamGenerator<class_AudioStreamGenerator>` to play back the generated audio in real-time.

Method Descriptions
-------------------

.. _class_AudioStreamGeneratorPlayback_method_can_push_buffer:

- :ref:`bool<class_bool>` **can_push_buffer** **(** :ref:`int<class_int>` amount **)** |const|

Returns ``true`` if a buffer of the size ``amount`` can be pushed to the audio sample data buffer without overflowing it, ``false`` otherwise.

----

.. _class_AudioStreamGeneratorPlayback_method_clear_buffer:

- void **clear_buffer** **(** **)**

Clears the audio sample data buffer.

----

.. _class_AudioStreamGeneratorPlayback_method_get_frames_available:

- :ref:`int<class_int>` **get_frames_available** **(** **)** |const|

Returns the number of audio data frames left to play. If this returned number reaches ``0``, the audio will stop playing until frames are added again. Therefore, make sure your script can always generate and push new audio frames fast enough to avoid audio cracking.

----

.. _class_AudioStreamGeneratorPlayback_method_get_skips:

- :ref:`int<class_int>` **get_skips** **(** **)** |const|

----

.. _class_AudioStreamGeneratorPlayback_method_push_buffer:

- :ref:`bool<class_bool>` **push_buffer** **(** :ref:`PackedVector2Array<class_PackedVector2Array>` frames **)**

Pushes several audio data frames to the buffer. This is usually more efficient than :ref:`push_frame<class_AudioStreamGeneratorPlayback_method_push_frame>` in C# and compiled languages via GDExtension, but :ref:`push_buffer<class_AudioStreamGeneratorPlayback_method_push_buffer>` may be *less* efficient in GDScript.

----

.. _class_AudioStreamGeneratorPlayback_method_push_frame:

- :ref:`bool<class_bool>` **push_frame** **(** :ref:`Vector2<class_Vector2>` frame **)**

Pushes a single audio data frame to the buffer. This is usually less efficient than :ref:`push_buffer<class_AudioStreamGeneratorPlayback_method_push_buffer>` in C# and compiled languages via GDExtension, but :ref:`push_frame<class_AudioStreamGeneratorPlayback_method_push_frame>` may be *more* efficient in GDScript.
