Thanks Jim,

From the subject I initially thought you were offering Mensa memberships
:-)

Afraid I am a member of Densa. The organisation for those *not* in Mensa.

Must admit one of the reasons I liked the 'IQ Test' label was that I think
this approach is cleverer (more general) than the 'J Test'. But it was
mainly named because it is an application of IQ modulation/demodulation.

I'd also write Mac and Windows versions, but since I don't use either very
much it isn't on my worksheet. If anyone else wants to do so, please do.
The only person I know who writes audio software for Windows doesn't use
'C', [1] so we lack a common language. :-)

FWIW I'm also wondering if there an optimum way to apply this to LP
for accurate wow and flutter measurements. Alas, since ye old 'quadrophonic'
have passed test discs these days don't seem to have 'IQ like' test
tracks. But there may well be a decent way to mimic this using the usual
3k-ish tone on a test LP.

Slainte,

Jim
