October 2012 Stereophile, page 21 David Chesky is serious about binaural (encoding) and is using BACCH filters now, and in all future CHESKY recordings, and I am excited big time.
This quote from stereophile article says it all...from David Chesky...
"I am going to do all Chesky recordings this way" "We've done this two -mircophone stereo thing for 50 and 60 years. We need to start doing things differently. I absolutely believe we can put you right in the center in Carnegie Hall, with all the perspective and density of the live performance"
HOT DAMN, now we're getting somewhere, and CHESKY is leading the way, again!
And of course, thank you to our WBF member Ralph Glasgal big time too.
Yes, and thanks to David Chesky for getting Ambiophonics some mention in Stereophile. Atkinson has steadfasly refused to come for a demo or review Ambiophonic gizmos, components, or priciples in Stereophile. On November 4th we will be hosting a meeting of all the audiophile Societys in Rockleigh, NJ where some eight different Ambiiophonics systems can be auditioned. Like stereo, Ambio can be implemented in lots of different ways, tweaks, and costs. All members of this list are welcome.
Both RACE and BACCH are examples of recursive crosstalk cancellation. You can read about the slight differences between them at
www.ambiophonics.org. Chesky uses mostly BACCH because he thinks audiophiles will not move their speakers closer together to achieve greater perfection. Both RACE and BACCH do work better at what they do if the speakers are about one third the angle used in most stereo systems. RACE is easily adjustable by the end listener for speaker angles and recordings, while the Chesky versiion of BACCH is fixed for the 60 degree angle and cannot be tweaked for non Chesky (or Chesky) recordings. Unfortunately for confirmed stereophiles, the 60 degree angle induces pinna direction finding pattern errors that not even RACE or BACCH can correct. So if you want perfection, think postiviely about moving your speakers closer together.
The Ambiophonics web page has just been updated and there are some really great pictures, tesimonials from new users in Europe, and a whole bunch of new products, mostly free, that allow you to play your existing library of LPs, CDs, and DVDs. the loudspeaker binaural way. It is just not true that you need purpose made binuaral recordings made with a dummy head to get a fantastic result by switching from the 60 degree loudspeaker triangle to the Ambiodipole. I am always amazed by how much ILD and ITD data is on the exisiting discs just waiting to be auralized. I know this stuff is technical and hard to believe but read the papers and tutorials and then try some of the demos or downloads. If you are well heeled there are the pioneering TacT Audio components or the little miniambio processor from Hong Kong!
