AudioListener
Records an audio stream from its surrounding AudioEmitters in the 3D world.
Memory category | Internal |

Member index 12
Description
AudioListener records an audio stream from its surrounding AudioEmitters in the 3D world. It provides a single Output pin which can be connected to other pins via Wires. If the parent is an Attachment, Camera, or PVInstance, the parent's world CFrame will be used for listening. If the parent is not one of these classes, the AudioListener effectively hears nothing.

AngleAttenuation
Type | Default | |
---|---|---|
BinaryString |
Represents a volume-over-angle curve that affects how loudly a AudioListener will hear the AudioEmitter, based on the angle between them and the LookVector associated with the AudioListener.
This property is internal and can't be accessed by scripts; it exists to support replication. See SetAngleAttenuation() for usage details.

DistanceAttenuation
Type | Default | |

BinaryString |
Represents a volume-over-distance curve that affects how loudly the AudioListener hears any AudioEmitters, based on the distance between them.
This property is internal and can't be accessed by scripts; it exists to support replication. See SetDistanceAttenuation() for usage details.

No parameters. | ||
Returns (1) | ||
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.

SetAngleAttenuation
Parameters (1) | ||
---|---|---|
curve | Dictionary | |
Returns (1) | ||
null |
Sets a volume-over-angle curve that affects how loudly a AudioListener will hear the AudioEmitter, based on the angle between them and the LookVector associated with the AudioListener.
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 from the perspective of the
AudioListener 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) to obtain the final audibility.
If the table is empty or nil
, the AudioEmitter defaults to using
an angle attenuation curve with the constant volume value of 1
.

Returns (1) | ||
null |
Sets a volume-over-distance curve that affects how loudly the AudioListener will hear any AudioEmitters, 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 from the perspective of the
AudioListener 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) to obtain the final audibility.
If the table is empty or nil
, the AudioListener defaults to
applying a constant volume of 1 everywhere.
