  55. Description
  56. -----------
  57. AudioStreamSample stores sound samples loaded from WAV files. To play the stored sound, use an :ref:`AudioStreamPlayer<class_AudioStreamPlayer>` (for non-positional audio) or :ref:`AudioStreamPlayer2D<class_AudioStreamPlayer2D>`/:ref:`AudioStreamPlayer3D<class_AudioStreamPlayer3D>` (for positional audio). The sound can be looped.
  58. This class can also be used to store dynamically-generated PCM audio data.
