indistinguishable soundfield

[syntheticwave]

Initiated by the fast development in hardware range the desire for synthesized sound, indistinguishable from the genuine sonic field, takes root. The principle of wave field synthesis offers just such possibility, however practical constrains broadly restrict that goal until today.

The procedure is described by wikipedia.

Whats the limitations and possibilities for the wave field synthesis in home cinema area for future by your opinion?

Kind Regards Helmut

Indistinguishable from what?

What you seem to be describing is a means to take a one channel recording and turn out a "sonically and spatially accurate" rendition of what it would have sounded like had it been recorded in multi-channel format to begin with.

And, unless you have that MC original to begin with, you have no basis for a real comparison.

Are you saying they have performed this test?

The principle of wave field synthesis offers just such possibility

That sounds like something Bose would come up with.

Hi, markw,
What I want to compare is the spatial soundfield on a dedicated place in the recording room regarding the spatial soundfield by a dedicated place in the rendition room. The goal for a genuine like rendition should be to generate the same temporal and spatial structure of the incoming wave fronts for both listeners.
Until today we far away from that possibility by the conventionally canal orientated procedures.

It sounds to me like it is describing the DSP modes of signal processing to produce an acoustic image of different room sizes or venues. I think he is referring to the advent of the processing chips in the last few years that not only do DSP but also surround sound processing and frequency response parametric equalization. He may in fact be referring to the new Yamaha receiver that does 11.1 surround processing and the other features I mentioned above. I think he may be saying the technology is now such that a realistic DSP soundfield approaches the real thing. Just a guess though.

...yes, by first sigth. You know the principle?

The wave fronts become build up by huygens principle from elementary waves. That generates no instabile phantom sources as like the conventionally procedures, but virtually sources. Its virtual starting point doesn't move with the listener, like as by a naturally source we perceiving it from all positions on its virtually starting point.

The principle goes far beyond. Each source generates in the recording room a huge amount of mirror sources. Its signal comes from all directions. It is not possible to reduce this spatial distribution onto the horizontal plane, nothing into a few canals.

When one takes into consideration the multiple micing, close micing, overdubs, and other intrusive processes iinvolved in modern recordings suxhas exho, eq, etc.., one cannot possibly say with any certainty that the end result in any way mimics reality.

Like some DSP modes in some processors, it may well be "pleasing", but to imply it successfully emulates reality is simply deluding oneself.

..thats rigth. Hence a new procedure is need.

If you not familar by the wave field synthesis procedure, it is described simply by some animations on my website , search "syntheticwave" in google, first hit or show wikipedia wave field synthesis.
