.. _class_AudioStreamMP3_property_data:

.. rst-class:: classref-property

:ref:`PackedByteArray<class_PackedByteArray>` **data** = ``PackedByteArray()``

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

- void **set_data** **(** :ref:`PackedByteArray<class_PackedByteArray>` value **)**
- :ref:`PackedByteArray<class_PackedByteArray>` **get_data** **(** **)**

Contains the audio data in bytes.

You can load a file without having to import it beforehand using the code snippet below. Keep in mind that this snippet loads the whole file into memory and may not be ideal for huge files (hundreds of megabytes or more).


.. tabs::

 .. code-tab:: gdscript

    func load_mp3(path):
        var file = FileAccess.open(path, FileAccess.READ)
        var sound = AudioStreamMP3.new()
        sound.data = file.get_buffer(file.get_length())
        return sound

 .. code-tab:: csharp

    public AudioStreamMP3 LoadMP3(string path)
    {
        using var file = FileAccess.Open(path, FileAccess.ModeFlags.Read);
        var sound = new AudioStreamMP3();
        sound.Data = file.GetBuffer(file.GetLength());
        return sound;
    }



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

----

.. _class_AudioStreamMP3_property_loop:

.. rst-class:: classref-property

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

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

- void **set_loop** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **has_loop** **(** **)**

If ``true``, the stream will automatically loop when it reaches the end.

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

----

.. _class_AudioStreamMP3_property_loop_offset:

.. rst-class:: classref-property

:ref:`float<class_float>` **loop_offset** = ``0.0``

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

- void **set_loop_offset** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_loop_offset** **(** **)**

Time in seconds at which the stream starts after being looped.
