enum **LoopMode**:

- **LOOP_DISABLED** = **0** --- Audio does not loop.

- **LOOP_FORWARD** = **1** --- Audio loops the data between loop_begin and loop_end playing forward only.

- **LOOP_PING_PONG** = **2** --- Audio loops the data between loop_begin and loop_end playing back and forth.

- **LOOP_BACKWARD** = **3** --- Audio loops the data between loop_begin and loop_end playing backward only.

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

AudioStreamSample stores sound samples loaded from ``.wav`` files. To play the stored sound use an :ref:`AudioStreamPlayer<class_AudioStreamPlayer>` (for background music) or :ref:`AudioStreamPlayer2D<class_AudioStreamPlayer2D>`/:ref:`AudioStreamPlayer3D<class_AudioStreamPlayer3D>` (for positional audio). The sound can be looped.

This class can also be used to store dynamically generated PCM audio data.

- :ref:`int<class_int>` **mix_rate**

+----------+---------------------+
| *Setter* | set_mix_rate(value) |
+----------+---------------------+
| *Getter* | get_mix_rate()      |
+----------+---------------------+

The sample rate for mixing this audio.

----

.. _class_AudioStreamSample_property_stereo:

- :ref:`bool<class_bool>` **stereo**

+----------+-------------------+
| *Setter* | set_stereo(value) |
+----------+-------------------+
| *Getter* | is_stereo()       |

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

.. _class_AudioStreamSample_method_save_to_wav:

- :ref:`Error<enum_@GlobalScope_Error>` **save_to_wav** **(** :ref:`String<class_String>` path **)**

Saves the AudioStreamSample as a WAV file to ``path``. Samples with IMA ADPCM format can't be saved.

Note that a ``.wav`` extension is automatically appended to ``path`` if it is missing.
