| 17 | |
| 18 | A AudioEngine can have exactly one listener, that defines the position and orientation |
| 19 | of the person listening to the sounds defined by the objects placed within the audio engine. |
| 20 | |
| 21 | In most cases, the AudioListener should simply be a child of the Camera element in QtQuick3D. |
| 22 | This will ensure that the sound experience is aligned with the visual rendering of the scene. |
