	<description>
		AudioStreamSample stores sound samples loaded from WAV files. To play the stored sound, use an [AudioStreamPlayer] (for non-positional audio) or [AudioStreamPlayer2D]/[AudioStreamPlayer3D] (for positional audio). The sound can be looped.
		This class can also be used to store dynamically-generated PCM audio data.

		<member name="data" type="PackedByteArray" setter="set_data" getter="get_data" default="PackedByteArray(  )">
			Contains the audio data in bytes.
			[b]Note:[/b] This property expects signed PCM8 data. To convert unsigned PCM8 to signed PCM8, subtract 128 from each byte.

		<member name="format" type="int" setter="set_format" getter="get_format" enum="AudioStreamSample.Format" default="0">
			Audio format. See [enum Format] constants for values.

		<member name="loop_begin" type="int" setter="set_loop_begin" getter="get_loop_begin" default="0">
			The loop start point (in number of samples, relative to the beginning of the sample). This information will be imported automatically from the WAV file if present.
		</member>
		<member name="loop_end" type="int" setter="set_loop_end" getter="get_loop_end" default="0">
			The loop end point (in number of samples, relative to the beginning of the sample). This information will be imported automatically from the WAV file if present.

			If [code]true[/code], audio is stereo.
