This makes it easier to hear sound while setting up the node. Since this changes the default value, this may break existing projects slightly. This also tweaks the Unit Size editor property hint for better usability. See discussion in #25468.

Plays positional sound in 3D space.
|

</brief_description>

<description>
|
|
Plays a sound effect with directed sound effects, dampens with distance if needed, generates effect of hearable position in space. For greater realism, a low-pass filter is automatically applied to distant sounds. This can be disabled by setting [member attenuation_filter_cutoff_hz] to [code]20500[/code].
|
|
By default, audio is heard from the camera position. This can be changed by adding a [Listener3D] node to the scene and enabling it by calling [method Listener3D.make_current] on it.
|
|
See also [AudioStreamPlayer] to play a sound non-positionally.
|
|
[b]Note:[/b] Hiding an [AudioStreamPlayer3D] node does not disable its audio output. To temporarily disable an [AudioStreamPlayer3D]'s audio output, set [member unit_db] to a very low value like [code]-100[/code] (which isn't audible to human hearing).
