<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.

<methods>
<method name="add_stream">
<return type="void" />
<param index="0" name="index" type="int" />
<param index="1" name="stream" type="AudioStream" />
<param index="2" name="weight" type="float" default="1.0" />
<description>
Insert a stream at the specified index. If the index is less than zero, the insertion occurs at the end of the underlying pool.
</description>
</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.
</description>
</method>
<method name="get_stream_probability_weight" qualifiers="const">
<return type="float" />
<param index="0" name="index" type="int" />
<description>
Returns the probability weight associated with the stream at the given index.
</description>
</method>
<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.
</description>
</method>
<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.
</description>
</method>
<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.

<members>
<member name="playback_mode" type="int" setter="set_playback_mode" getter="get_playback_mode" enum="AudioStreamRandomizer.PlaybackMode" default="0">
Controls how this AudioStreamRandomizer picks which AudioStream to play next.
</member>
<member name="random_pitch" type="float" setter="set_random_pitch" getter="get_random_pitch" default="1.0">
The intensity of random pitch variation. A value of 1 means no variation.

<member name="random_volume_offset_db" type="float" setter="set_random_volume_offset_db" getter="get_random_volume_offset_db" default="0.0">
The intensity of random volume variation. A value of 0 means no variation.

The number of streams in the stream pool.

<constants>
<constant name="PLAYBACK_RANDOM_NO_REPEATS" value="0" enum="PlaybackMode">
Pick a stream at random according to the probability weights chosen for each stream, but avoid playing the same stream twice in a row whenever possible. If only 1 sound is present in the pool, the same sound will always play, effectively allowing repeats to occur.
</constant>
<constant name="PLAYBACK_RANDOM" value="1" enum="PlaybackMode">
Pick a stream at random according to the probability weights chosen for each stream. If only 1 sound is present in the pool, the same sound will always play.
</constant>
<constant name="PLAYBACK_SEQUENTIAL" value="2" enum="PlaybackMode">
Play streams in the order they appear in the stream pool. If only 1 sound is present in the pool, the same sound will always play.
