A listener position adaptive stereo system for object-based reproduction
A listener position adaptive stereo system for object-based reproduction
Stereo reproduction of spatial audio allows the creation of strong acoustic images when the listener is placed in the sweet spot, a small region around the axis of symmetry between both loudspeakers. If the listener moves slightly towards one of the sources, however, the images collapse at the loudspeaker the listener is leaning to. In order to overcome such limitation, a stereo reproduction device which adapts the sweet spot to the listener position is presented here. This device introduces a new approach which maximizes listener inversion by rendering object based audio, in which several audio objects or sources are placed at different angles between the stereo span. By using a video tracking device, the listener is allowed to move freely between the loudspeaker span, whilst that loudspeaker outputs are compensated using conventional panning algorithms so that the position of the different audio objects is kept independent of the listener position

Abstract
Stereo reproduction of spatial audio allows the creation of strong acoustic images when the listener is placed in the sweet spot, a small region around the axis of symmetry between both loudspeakers. If the listener moves slightly towards one of the sources, however, the images collapse at the loudspeaker the listener is leaning to. In order to overcome such limitation, a stereo reproduction device which adapts the sweet spot to the listener position is presented here. This device introduces a new approach which maximizes listener inversion by rendering object based audio, in which several audio objects or sources are placed at different angles between the stereo span. By using a video tracking device, the listener is allowed to move freely between the loudspeaker span, whilst that loudspeaker outputs are compensated using conventional panning algorithms so that the position of the different audio objects is kept independent of the listener position
