AudioRoom QML Type▲
-
Import Statement: import QtQuick3D.SpatialAudio
-
Group: AudioRoom is part of quick3d_spatialaudio, multimedia_audio_qml
Detailed Description▲
Defines a room for the spatial audio engine.
If the listener is inside a room, first order sound reflections and reverb matching the rooms properties will get applied to the sound field.
A room is always square and defined by its center position, its orientation and dimensions. Each of the 6 walls of the room can be made of different materials that will contribute to the computed reflections and reverb that the listener will experience while being inside the room.
If multiple rooms cover the same position, the engine will use the room with the smallest volume.

reflectionGain : float▲
A gain factor for reflections generated in this room. A value from 0 to 1 will dampen reflections, while a value larger than 1 will apply a gain to reflections, making them louder.
The default is 1, a factor of 0 disables reflections. Negative values are mapped to 0.
reverbBrightness : float▲
A brightness factor to be applied to the generated reverb. A positive value will increase reverb for higher frequencies and dampen lower frequencies, a negative value does the reverse.
The default is 0.
reverbGain : float▲
A gain factor for reverb generated in this room. A value from 0 to 1 will dampen reverb, while a value larger than 1 will apply a gain to the reverb, making it louder.
The default is 1, a factor of 0 disables reverb. Negative values are mapped to 0.
reverbTime : float▲
A factor to be applies to all reverb timings generated for this room. Larger values will lead to longer reverb timings, making the room sound larger.
The default is 1. Negative values are mapped to 0.
