Several years I work on project aimed to restore the genuine sound field in all three space dimensions physically. Basis is wfs, but not based by the usual loudspeaker rows in ring around the listener. The loudspeaker field placed only behind the screen wall. Regarding the connected procedure for the "transformation of the early soundfield" I have a German patent. It is possible to change virtual the size of the rendition room by this procedure. The way is described by my www.syntheticwave.de site.
For some further ideas in that connection I search a partner for further investigation or realization.
Some ideas for solve remaining problems regarding the soundfield reconstruction.
Investigation or production possibilities
