--- name: AudioListener last_updated: 2026-06-10T23:09:11Z inherits: - Instance - Object type: class memory_category: Internal summary: "Records an audio stream from its surrounding AudioEmitters in the 3D world." --- # Class: AudioListener > Records an audio stream from its surrounding > [AudioEmitters](/docs/reference/engine/classes/AudioEmitter.md) in the 3D world. ## Description [AudioListener](/docs/reference/engine/classes/AudioListener.md) records an audio stream from its surrounding [AudioEmitters](/docs/reference/engine/classes/AudioEmitter.md) in the 3D world. It provides a single **Output** pin which can be connected to other pins via [Wires](/docs/reference/engine/classes/Wire.md). If the parent is an [Attachment](/docs/reference/engine/classes/Attachment.md), [Camera](/docs/reference/engine/classes/Camera.md), or [PVInstance](/docs/reference/engine/classes/PVInstance.md), the parent's world [CFrame](/docs/reference/engine/datatypes/CFrame.md) will be used for listening. If the parent is not one of these classes, the [AudioListener](/docs/reference/engine/classes/AudioListener.md) effectively hears nothing. ## Code Samples **Camera Listener** ```lua local listener = Instance.new("AudioListener") local output = Instance.new("AudioDeviceOutput") local wire = Instance.new("Wire") listener.Parent = workspace.Camera wire.Parent = listener output.Parent = wire wire.SourceInstance = listener wire.TargetInstance = output ``` ## Properties ### Property: AudioListener.AcousticSimulationEnabled ```json { "type": "boolean", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Simulation", "capabilities": [ "Audio" ] } ``` Determines whether sound being heard by this [AudioListener](/docs/reference/engine/classes/AudioListener.md) shoud automatically implement features of acoustic simulation, such as occlusion (being muffled through walls), diffraction (bending around corners), and reverberation (echoing off of walls), when being sourced from an [AudioEmitter](/docs/reference/engine/classes/AudioEmitter.md). Note that the [AudioEmitter](/docs/reference/engine/classes/AudioEmitter.md) also needs its [AcousticSimulationEnabled](/docs/reference/engine/classes/AudioEmitter.md) property set to `true` for the effects to occur. ### Property: AudioListener.AngleAttenuation ```json { "type": "Flyweight", "access": "ReadOnly", "security": { "read": "RobloxEngineSecurity", "write": "RobloxEngineSecurity" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Listening", "capabilities": [ "Audio" ] } ``` Represents a volume-over-angle curve that affects how loudly a [AudioListener](/docs/reference/engine/classes/AudioListener.md) will hear the [AudioEmitter](/docs/reference/engine/classes/AudioEmitter.md), based on the angle between them and the [LookVector](/docs/reference/engine/datatypes/CFrame.md) associated with the [AudioListener](/docs/reference/engine/classes/AudioListener.md). This property is internal and can't be accessed by scripts; it exists to support replication. See [SetAngleAttenuation()](/docs/reference/engine/classes/AudioListener.md) for usage details. ### Property: AudioListener.AudioInteractionGroup ```json { "type": "string", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Interactions", "capabilities": [ "Audio" ] } ``` Controls which [AudioEmitters](/docs/reference/engine/classes/AudioEmitter.md) are audible to this [AudioListener](/docs/reference/engine/classes/AudioListener.md). Emitters that share an interaction group can be heard by this Listener. ### Property: AudioListener.DistanceAttenuation ```json { "type": "Flyweight", "access": "ReadOnly", "security": { "read": "RobloxEngineSecurity", "write": "RobloxEngineSecurity" }, "serialization": { "can_load": true, "can_save": true }, "thread_safety": "ReadSafe", "category": "Listening", "capabilities": [ "Audio" ] } ``` Represents a volume-over-distance curve that affects how loudly the [AudioListener](/docs/reference/engine/classes/AudioListener.md) hears any [AudioEmitters](/docs/reference/engine/classes/AudioEmitter.md), based on the distance between them. This property is internal and can't be accessed by scripts; it exists to support replication. See [SetDistanceAttenuation()](/docs/reference/engine/classes/AudioListener.md) for usage details. ### Property: AudioListener.SimulationFidelity ```json { "type": "AudioSimulationFidelity", "access": "ReadWrite", "security": { "read": "None", "write": "None" }, "serialization": { "can_load": true, "can_save": true }, "deprecated": true, "thread_safety": "ReadSafe", "category": "Simulation", "capabilities": [ "Audio" ] } ``` Controls how detailed the audio simulation should be for this [AudioListener](/docs/reference/engine/classes/AudioListener.md), similar to [MeshPart.CollisionFidelity](/docs/reference/engine/classes/MeshPart.md) or [MeshPart.RenderFidelity](/docs/reference/engine/classes/MeshPart.md). [AudioListeners](/docs/reference/engine/classes/AudioListener.md) and [AudioEmitters](/docs/reference/engine/classes/AudioEmitter.md) which disagree on the necessary level of detail will use the less-detailed option. ## Methods ### Method: AudioListener:GetAngleAttenuation **Signature:** `AudioListener:GetAngleAttenuation(): Dictionary` Returns a table mapping angle to volume. Keys are numbers between `0` and `180` (inclusive), while values are numbers between `0` and `1` (inclusive) describing how volume attenuates depending on direction. This method returns an empty table if the default angle attenuation curve is being used. *Security: None · Thread Safety: Unsafe · Capabilities: Audio* **Returns:** `Dictionary` — Table mapping angle to volume, as described above. ### Method: AudioListener:GetAudibilityFor **Signature:** `AudioListener:GetAudibilityFor(emitter: AudioEmitter): float` Calculates how audible an [AudioEmitter](/docs/reference/engine/classes/AudioEmitter.md) is for this listener. The resulting volume, ranging from `0` to `1`, accounts for distance and angle attenuation on both the emitter and listener. *Security: None · Thread Safety: Unsafe · Capabilities: Audio* **Parameters:** | Name | Type | Default | Description | |------|------|---------|-------------| | `emitter` | `AudioEmitter` | | | **Returns:** `float` ### Method: AudioListener:GetConnectedWires **Signature:** `AudioListener:GetConnectedWires(pin: string): List` Returns an array of [Wires](/docs/reference/engine/classes/Wire.md) that are connected to the specified pin. [AudioListener](/docs/reference/engine/classes/AudioListener.md) has one "Output" pin. *Security: None · Thread Safety: Unsafe · Capabilities: Audio* **Parameters:** | Name | Type | Default | Description | |------|------|---------|-------------| | `pin` | `string` | | An input or output pin on this instance | **Returns:** `List` — An array of [Wires](/docs/reference/engine/classes/Wire.md) ### Method: AudioListener:GetDistanceAttenuation **Signature:** `AudioListener:GetDistanceAttenuation(): Dictionary` Returns a table mapping distance to volume. Keys are numbers greater than or equal to 0, while values are numbers between 0 and 1 (inclusive) describing how volume attenuates over distance. This method returns an empty table if the default distance attenuation curve is being used. *Security: None · Thread Safety: Unsafe · Capabilities: Audio* **Returns:** `Dictionary` ### Method: AudioListener:GetInputPins **Signature:** `AudioListener:GetInputPins(): Array` Gets the list of pins that [Wire](/docs/reference/engine/classes/Wire.md) can use in [Wire.TargetName](/docs/reference/engine/classes/Wire.md) to connect to this instance via its [Wire.TargetInstance](/docs/reference/engine/classes/Wire.md) property. For [AudioListener](/docs/reference/engine/classes/AudioListener.md), there are none. *Security: None · Thread Safety: Unsafe · Capabilities: Audio* **Returns:** `Array` — An array of strings representing valid pin names. ### Method: AudioListener:GetInteractingEmitters **Signature:** `AudioListener:GetInteractingEmitters(): List` Returns an array of [AudioEmitters](/docs/reference/engine/classes/AudioEmitter.md) that share an [AudioInteractionGroup](/docs/reference/engine/classes/AudioListener.md) with the listener. *Security: None · Thread Safety: Unsafe · Capabilities: Audio* **Returns:** `List` ### Method: AudioListener:GetOutputPins **Signature:** `AudioListener:GetOutputPins(): Array` Gets the list of pins that [Wire](/docs/reference/engine/classes/Wire.md) can use in [Wire.SourceName](/docs/reference/engine/classes/Wire.md) to connect to this instance via its [Wire.SourceInstance](/docs/reference/engine/classes/Wire.md) property. For [AudioListener](/docs/reference/engine/classes/AudioListener.md), this is `Output` only. *Security: None · Thread Safety: Unsafe · Capabilities: Audio* **Returns:** `Array` — An array of strings representing valid pin names. ### Method: AudioListener:SetAngleAttenuation **Signature:** `AudioListener:SetAngleAttenuation(curve: Dictionary): ()` Sets a volume-over-angle curve that affects how loudly a [AudioListener](/docs/reference/engine/classes/AudioListener.md) will hear the [AudioEmitter](/docs/reference/engine/classes/AudioEmitter.md), based on the angle between them and the [LookVector](/docs/reference/engine/datatypes/CFrame.md) associated with the [AudioListener](/docs/reference/engine/classes/AudioListener.md). The curve is represented by a table mapping angle keys to volume values. Keys are expected to be unique numbers between `0` and `180` (inclusive), while values are expected to be numbers between `0` and `1` (inclusive). Tables containing up to 400 key-value pairs are supported. The volume of a [AudioEmitter](/docs/reference/engine/classes/AudioEmitter.md) from the perspective of the [AudioListener](/docs/reference/engine/classes/AudioListener.md) at an angle `a` is determined by linearly interpolating between the volume levels for the points on the curve whose angle values are directly above and below `a`. If there is either no point below `a` or no point above `a`, the volume level of the other point is chosen. Essentially, the curve is a sequence of points connected by straight lines, and beyond its left and right endpoints the curve extends outward at their respective volume levels. This volume will be multiplied with the volumes from all other attenuation curves (including the ones on the sending [AudioEmitter](/docs/reference/engine/classes/AudioEmitter.md)) to obtain the final audibility. If the table is empty or `nil`, the [AudioListener](/docs/reference/engine/classes/AudioListener.md) defaults to using an angle attenuation curve with the constant volume value of `1`. *Security: None · Thread Safety: Unsafe · Capabilities: Audio* **Parameters:** | Name | Type | Default | Description | |------|------|---------|-------------| | `curve` | `Dictionary` | | | **Returns:** `()` **Camera Listener** ```lua local Workspace = game:GetService("Workspace") local currentCamera = Workspace.CurrentCamera local listener = Instance.new("AudioListener") listener.Parent = currentCamera local wire = Instance.new("Wire") wire.Parent = listener local output = Instance.new("AudioDeviceOutput") output.Parent = wire listener:SetAngleAttenuation({ [0] = 1, -- Emitters directly in front of the listener will be full volume [180] = 0.5 -- Emitters directly behind the listener will be half volume }) wire.SourceInstance = listener wire.TargetInstance = output ``` ### Method: AudioListener:SetDistanceAttenuation **Signature:** `AudioListener:SetDistanceAttenuation(curve: Dictionary): ()` Sets a volume-over-distance curve that affects how loudly the [AudioListener](/docs/reference/engine/classes/AudioListener.md) will hear any [AudioEmitters](/docs/reference/engine/classes/AudioEmitter.md), based on the distance between them. The curve is represented by a table mapping distance keys to volume values. Keys are expected to be unique numbers greater than or equal to 0, while values are expected to be numbers between 0 and 1 (inclusive). Tables containing up to 400 key-value pairs are supported. The volume of a [AudioEmitter](/docs/reference/engine/classes/AudioEmitter.md) from the perspective of the [AudioListener](/docs/reference/engine/classes/AudioListener.md) at a distance `d` is determined by linearly interpolating between the volume levels for the points on the curve whose distance values are directly above and below `d`. If there is either no point below `d` or no point above `d`, the volume level of the other point is chosen. Essentially, the curve is a sequence of points connected by straight lines, and beyond its left and right endpoints the curve extends outward infinitely at their respective volume levels. This volume will be multiplied with the volumes from all other attenuation curves (including the ones on the sending [AudioEmitter](/docs/reference/engine/classes/AudioEmitter.md)) to obtain the final audibility. If the table is empty or `nil`, the [AudioListener](/docs/reference/engine/classes/AudioListener.md) defaults to applying a constant volume of 1 everywhere. *Security: None · Thread Safety: Unsafe · Capabilities: Audio* **Parameters:** | Name | Type | Default | Description | |------|------|---------|-------------| | `curve` | `Dictionary` | | | **Returns:** `()` ## Events ### Event: AudioListener.WiringChanged **Signature:** `AudioListener.WiringChanged(connected: boolean, pin: string, wire: Wire, instance: Instance)` Event that fires after a [Wire](/docs/reference/engine/classes/Wire.md) becomes connected or disconnected, and that [Wire](/docs/reference/engine/classes/Wire.md) is now or was previously connected to a pin on the [AudioListener](/docs/reference/engine/classes/AudioListener.md) and to some other wirable instance. *Security: None · Capabilities: Audio* **Parameters:** | Name | Type | Description | |------|------|-------------| | `connected` | `boolean` | Whether the instance got connected or disconnected. | | `pin` | `string` | The pin on the [AudioListener](/docs/reference/engine/classes/AudioListener.md) that the [Wire](/docs/reference/engine/classes/Wire.md) targets. | | `wire` | `Wire` | The [Wire](/docs/reference/engine/classes/Wire.md) between the [AudioListener](/docs/reference/engine/classes/AudioListener.md) and the other instance. | | `instance` | `Instance` | The other instance that is or was connected through the [Wire](/docs/reference/engine/classes/Wire.md). | ## Inherited Members ### From [Instance](/docs/reference/engine/classes/Instance.md) -
