    \qmltype AudioRoom
    \inqmlmodule QtQuick3D.SpatialAudio
    \ingroup quick3d_spatialaudio
    \ingroup multimedia_audio_qml
 
    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.
