Umm - fun? Historical interest, as I'd never heard the original? Insufficient
other things to do? :-)
For those interested, the original paper describing the newer process is "Signal Processing for
Simulating Realistic Stereo Images" preprint 3423 of the 93rd AES Convention October 1992 (San
Francisco)...at some point I'll get round to doing an Ambisonic version of that, too - but it is
covered by a current patent US 5671287 <http://www.google.com/patents/US5671287> so there could be
problems releasing something based on the technology.

That's interesting - it kind of chimes with some experiments I have been
doing recently with digital
recreations of Gerzon's spreaders, which used phase shift based processing.
Although technically
they are doing what is described in MAG's original hand written reports, the
way they sound doesn't
really correspond very closely to description of how they should sound in
the same report.
Er ... why are you recreating Gerzon's
*analogue* spreaders when you can look at
Gerzon's *digital* spreader. This is called the
PS22 Stereo Maker plug-in from Waves Audio.
This is only a stereo spreader, but that is
actually a minor detail.
The screen shot on Page 21 of their manual
(page 22 in the PDF file) should give you the
idea; visit:
