touche!

It also shows why any attempt to reproduce concert hall acousitcs using the capture/store/retrieve/reproduce strategy is doomed to fail no matter how many recording playback channels are used.
I presume this means that anything already captured is hopelessly lost.

The characteristic parameters of the acoustics where the recording was made are irretrievably lost. However, an acoustic space suitable for the type of music performed can usually be reconstructed from what remains available. It just won't be exactly the same space. At best, similar.

I should point out that acoustics of place are not constant. Not only do they vary with conditons of state, they also vary with how many people are in the audience, where they are seated, what kind of clothing they are wearing. This is well known and can be easily seen from measured data for concert halls given when they are empty and filled. There can be substantial changes in parameters. The precise field the listener experiences will also depend on where in the audience he is seated.

Is this correct?
Yes that's right....if you consider a United States Patent in the public domain unpublished.

Besides no cite to the patent (there's about 8 million to choose from), you said, "Only enough of the model was revealed to obtain the patent." So, it remains, you're making extravagant claims and not doing anything whatever to back them up.

I'm having a hard time taking you seriously, and I'm not exactly notorious for belief in woo-woo in audio.

You fellows are way behind the times.
Back in the 1980s Yamaha engineers went around to many famous concert halls and churches to record the acoustics. They stuck all those acoustics onto a microchip and into a box. You can call them up with a push of the remote control button.

I have one of these boxes.

Perhaps I'll be coy the way Curl is with his wire measurements.

And you'll be taken equally seriously. Actually, much less seriously, since John provided his spectra and test setup as well as allowed in a skeptical observer. He's probably wrong, but he's openly and honestly wrong.

When you're ready to contribute and move beyond trolling, I'll be most interested in a serious discussion. Until that point, I really don't think that anything you post is worth a response from anyone.
