Listeners

In this guide we'll cover how to add FMOD listeners to your godot project.

Fmod listener nodes

FmodListener2D and FmodListener3D are nodes to add a FMOD listener and bind it to them, this means position of the FMOD listener will match position of the FmodListener node.

listener-image

Properties:

listener_index

Index of the listener. You can have up to 8 listener concurrently.

is_locked

If true, listener will not update its position according to node's position.

weight

Used to compute the relative contribution to the final sound.

Using FmodServer api

You can add and remove listeners using FmodServer api: 

1
2
func _ready():
    FmodServer.add_listener(0, self)

In this script we set a listener with index 0 and attached it to the current node. 

1
2
func _ready():
    FmodServer.remove_listener(0, self)

In this script we remove the listener with index 0 attached to the current node.

You can also set the listener weight using FmodServer:

1
FmodServer.set_system_listener_weight(0, 1.5)

In this script we set the weight of the listener with index 0 to 1.5.
