- 受け継いでいるクラス：Instance

## プロパティ

- `AudioListener.AcousticSimulationEnabled: boolean`：Determines whether acoustic simulation should be used for this AudioListener.
- `AudioListener.AngleAttenuation: BinaryString`：Represents how the perceived volume of the emitted sound changes based on the angle between a AudioEmitter and the Datatype.CFrame.LookVector|LookVector associated with the AudioListener.
- `AudioListener.AudioInteractionGroup: string`：Controls which Class.AudioEmitter|AudioEmitters are audible to this AudioListener.
- `AudioListener.DistanceAttenuation: BinaryString`：Represents how the perceived volume of emitted sounds change as the distance between Class.AudioEmitter|AudioEmitters and the AudioListener increases.
- `AudioListener.PositionInstance: Instance`：The Instance whose position and orientation is used as the listener's position if Class.AudioListener.PositionType|PositionType is set to ListenerPositionType.Instance.
- `AudioListener.PositionType: ListenerPositionType`：Determines how the AudioListener determines its 3D location.

## メソッド

- `AudioListener:GetAngleAttenuation(): Dictionary`：Gets the angle attenuation curve that the AudioListener is using, or an empty table if it's using the default curve.
- `AudioListener:GetAudibilityFor(emitter: AudioEmitter): float`：Calculates how audible an AudioEmitter is for this listener
- `AudioListener:GetConnectedWires(pin: string): List<Wire>`：Returns an array of Class.Wire|Wires that are connected to the specified pin.
- `AudioListener:GetDistanceAttenuation(): Dictionary`：Gets the distance attenuation curve that the AudioListener is using, or an empty table if it's using the default curve.
- `AudioListener:GetInputPins(): Array`：Gets the list of pins that Wire can use in Wire.TargetName to connect to this instance via its Wire.TargetInstance property.
- `AudioListener:GetInteractingEmitters(): List<AudioEmitter>`：Lists all Class.AudioEmitter|AudioEmitters that this listener is capable of hearing.
- `AudioListener:GetOutputPins(): Array`：Gets the list of pins that Wire can use in Wire.SourceName to connect to this instance via its Wire.SourceInstance property.
- `AudioListener:SetAngleAttenuation(curve: Dictionary): ()`：Sets the angle attenuation curve that the AudioListener should use, or uses a constant curve of volume 1 if none is provided.
- `AudioListener:SetDistanceAttenuation(curve: Dictionary): ()`：Sets the distance attenuation curve that the AudioListener should use, or uses an inverse rolloff curve if none is provided.

## イベント

- `AudioListener.WiringChanged(connected: boolean, pin: string, wire: Wire, instance: Instance)`：Fires when another instance is connected to or disconnected from the AudioListener via a Wire.
