- 受け継いでいるクラス：Instance

## プロパティ

- `AudioEmitter.AcousticSimulationEnabled: boolean`：Determines whether acoustic simulation should be used for this AudioEmitter.
- `AudioEmitter.AngleAttenuation: BinaryString`：Represents how the perceived volume of the emitted sound changes based on the angle between a AudioListener and the Datatype.CFrame.LookVector|LookVector associated with the AudioEmitter.
- `AudioEmitter.AudioInteractionGroup: string`：Controls which Class.AudioListener|AudioListeners are capable of hearing this AudioEmitter.
- `AudioEmitter.DistanceAttenuation: BinaryString`：Represents how the perceived volume of the emitted sound changes as the distance between a AudioListener and the AudioEmitter increases.
- `AudioEmitter.DistanceAttenuationBounds: NumberRange`：The minimum and maximum distance range used by the selected Class.AudioEmitter.DistanceAttenuationMode|DistanceAttenuationMode preset.
- `AudioEmitter.DistanceAttenuationMode: DistanceAttenuationMode`：Determines how the volume of this AudioEmitter attenuates over distance.
- `AudioEmitter.PositionInstance: Instance`：The Instance whose position and orientation is used as the emitter's position if Class.AudioEmitter.PositionType|PositionType is set to EmitterPositionType.Instance.
- `AudioEmitter.PositionType: EmitterPositionType`：Determines how the AudioEmitter determines its 3D location.

## メソッド

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

## イベント

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