Hi,

some days ago i found a interseting site. It is describing a procedure, which would allow creating a virtually copy of the genuine soundfield in all room dimensions. Should become that really possible in future by your opinion?:confused:

The link: http://www.wave-field-synthesis.de/

    Well , it had some interesting basic animations.

    But when they said,

    "Prof. Berkhout invented the procedure 1988 at the University of Delft, based on the Kirchhoff- Helmholtz integral:

    I said, 'No way, man !".

    Mainly because I didn't know what the heck they were talking about. :o


    BUT: nice first post, Earlybird. You might want to consider some research on the positive/negative aspects of cables vs wires.

    Holy hell that's thick!

    Mind giving a rundown of the basic idea? I mean I can suffer through some seriously rough technical documents and understand what they are saying but with all the advanced topics and the not so great translation on the English side, it's hard to get a grasp of what is going on.

    Something tells me that you didn't just "find" that site either but you might actually have something to do with it.

    I thought so. I found it odd that some dude from Germany would just pop in to an American forum and post a post like this!

    You wacky Germans! You're so sneaky! :;) :p:D




    So any help on a simpler explanation on what the article is about?

    Holy smokes! I've been to some telcom classes that had some pretty dry technical info that I unfortunately understood, but that's a bit over the top for me.

    Cool animated pics though.
    My equipment sig felt inadequate and deleted itself.

    ...It’s a hard task, describing complicated connections easily, let me try it:

    Imagine, you are situated in an opera house, best place, great tenor sings. Suddeny unexpected some bricklayers come in, build up a little housing around you. You are angrily, 56$ for the ticket and now you can hear nothing!:eek:
    But help is coming. One of the masons made holes into all walls, 10 cm in diameter, each on the other. Super, you hear Caruso as good as without the house. But now the electricians coming, sticking each hole by a loudspeaker. The sound is blocked again, but then, suddenly you hear likely the holes would be open. The electricians have supplied each speaker by a small amplifier and a microphone on the outside of the holes. Nothing is changed, speakers and microphones working well today.

    The problem is only; you need one discrete channel for each micro, if you want to build the speakers into your living room walls. The second, mostly bigger problem is your wife, if you want to load all walls around in your living room by loudspeakers.:mad:

    The webside does describe nothing else as a solution for those two problems. It describes a way for build up the direct wave and the first early reflections from a dry recorded audio signal in the same spatial behavior as in the opera house. That’s the core of each acoustic, by conventionally loudspeaker reproduction we are far away from this goal. The reverberation tail created from the impulse response, that’s practice in all studios today so. This impulse response becomes suppressed for the early reflection time, so that the first reflections don’t produce a second time. The reverberation comes from all directions by such approach, likely in the opera house. By including the reflecting walls ofyour living room, as it is known from the sound projectors, you can resign the loudspeakers all around, only those behind the picture screen remain. But the gadget isn’t producing virtually loudspeakers, as do it the sound projectors. The loudspeaker field simulates the source itself. That shouldn't be a little revolution in audio ?

    The ony remaining problem woud be the other problems with your wife.:D
