George, please let me dispel any rumors!

This is exactly what I was describing; originally I did this with the CEDAR
AZ-1, but now I use CEDAR Cambridge Phase Corrector module. CEDAR have
renamed the process, since 'azimuth correction' was not as accurate as
'phase correction'.

All of the processes I described previously are the ones I now use in CEDAR
Cambridge (with optional modules). Note that I find it helpful to
auto-balance L-R levels as part of the processing chain, prior to summing.

And now that we have gone brand-specific, perhaps we'll hear from others
using Cube-Tec, etc.
