Most existing and arising 2D and 3D loudspeaker setups are primarily designed for cinema, and intend to render a stable frontal soundscape at the expense of precision in the reproduction of the non-frontal information. Another difficulty related to the introduction of new surround sound standards is the need for an efficient mixing approach to adapt 3D audio content to stereo and surround domestic systems. The project presented here aims at providing tools to overcome those two limitations on two-channel and 2D-multichannel setups, i.e. to enable the reproduction of 2D-and 3D-surround content on pure 2D-systems, to ensure a stable reproduction of the lateral sound images and a homogeneous envelopment of the listener.
