Hi Paul--
I'm not sure how closely my method resembles Blumlein's patch, bus as
Greg describes, I use EQ inserted between two MS plugs. I first
insert 18dB shelving EQ to the sides boosting from 0 Hz to around
250Hz even as high as 500Hz. I adjust the level to make the low
content on the sides quite obvious. Then I attenuate the exaggerated
frequencies on the sides with 2-5 narrow bands of parametric EQ. Then
I re-adjust the shelf blend to taste. Together, with prior parametric
notching of the exaggerated lower mid frequencies in the middle of
the field, the lowest octaves can sound more even across the stereo
field. A subtle, breathing quality can sometimes be coaxed out too.
As David pointed out a while back, there's an MS mode option with
APEQ that might allow one do what Greg is doing with iZotope.
I'd be happy to try my method on a sample file.
Enjoyed your recordings! The character of the energy feels so
different from the habitats I know well in North America. There
seems to be very different "air" qualities in the two recordings.
Have any ideas about what accounts for this? Rob D.
