	<brief_description>
		Wraps a pool of audio streams with pitch and volume shifting.
	</brief_description>
	<description>
		Picks a random AudioStream from the pool, depending on the playback mode, and applies random pitch shifting and volume shifting during playback.

		</method>
		<method name="get_stream" qualifiers="const">
			<return type="AudioStream" />
			<param index="0" name="index" type="int" />
			<description>
				Returns the stream at the specified index.

		<method name="move_stream">
			<return type="void" />
			<param index="0" name="index_from" type="int" />
			<param index="1" name="index_to" type="int" />
			<description>
				Move a stream from one index to another.
			</description>
		</method>
		<method name="remove_stream">
			<return type="void" />
			<param index="0" name="index" type="int" />
			<description>
				Remove the stream at the specified index.

		<method name="set_stream">
			<return type="void" />
			<param index="0" name="index" type="int" />
			<param index="1" name="stream" type="AudioStream" />
			<description>
				Set the AudioStream at the specified index.

		<method name="set_stream_probability_weight">
			<return type="void" />
			<param index="0" name="index" type="int" />
			<param index="1" name="weight" type="float" />
			<description>
				Set the probability weight of the stream at the specified index. The higher this value, the more likely that the randomizer will choose this stream during random playback modes.
