Who will install thousands of loudspeakers in his livingroom wall For real?

Much more clever seem, construct a common model from recording room and playback room, as in the Holophony procedure. By those object based procedure, a combination of the model based and data based approach allows, constitute an common approach. In the near field of an large WFS loudspeaker field behind the silver screen, the playback room acoustics become subordinated matter. Thus, the common model allow subtracting playback room acoustic. Is easily comprehensible in this little animation:

We are at the work to build that. I hold the patent for the procedure since more as five years. The result will be the physikal reconstruction of the spatial sonic field.

..you shouldn't blab your wife, what is covered behind the silver screen. Simply say, a band would be playing!

Never mind the silver screen But who will install thousands of loudspeakers behind it You also need thousands of amplifiers, one for each speaker.

Is there anybody else besides you that still remembers Ambisonics?

P.S. Ambisonics and the 3DAA approach are not the same. Ambisonics is more like wave field synthesis with a limited number of loudspeakers whereas 3DAA really separates sound objects from playback. Ambisonics could act as a renderer for 3DAA content.

...you understand the principle, thanks for interest.

The loudspeakers are fixed in modules. The modules include the amplifiers. At four watts each we have four kW total power. Because of the perfect Loudspeaker adaptation ,the dynamics neraly unlimited, in principle.

The whole unit is connected via one light cable at the computer, which is rendering the 32 input channels to the 1024 speakers. That is not really a problem, from technical point of view, but also not really cheap.

Now you just need to convince the whole movie/audio industry of investing in completely new recording facilities/equipment in order to produce exclusively for your system. Piece of cake

...no other way remains for true spatial audio.

While on the subject of reproduction and measurements, I would like to present a few points for serious consideration. In order not to waste forum space here, and perhaps go off at a tangent, I would invite you to take a look at "Measurements and the Environment" at my blog <http://sound-unboxed.blogspot.com/>.

Surely these are highly personal views, but if there are kindred spirits who share at least some of the points of view, it could lead on to a renewed look at measurements and our understanding of sound and reproduction.

I hope the more knowledgeable among us would start an appropriate new thread to address such 'borderline' issues.

Most sincerely.

While on the subject of sound and sensible measurements, permit me to urge you, if you have a few minutes to spare and are open-minded about some 'lateral thinking' on stereo and realism, to visit < Sound... unboxed ! > and share your thoughts.

Whether you agree or disagree, I guess you too might share some of the problems raised by commonplace questions about reproduction, realism and the role of 2-channel stereo as we know it and implement it.

Thanks and regards.
