Eric,
I'd definitely be interested in reading your papers.
I recently bought an Mkh-30, as well as a 20, and am doing research
on possible surround recording with only 3 mics in Double M/S
configuration before I purchase a 3rd.
what little I've read about Double M/S suggested
using a single figure 8 for Side, along with a forward facing Mid,
plus a rear facing Mid. the suggestion is to use the same Side
signal to decode both the Front and Rear "Mids" into Front and Rear
L-R Stereo.
a Logical next microphone purchase (for general recording purposes)
would be a 40 or 50, but I'm not sure whether either will work
out well in a Double M/S with my existing mics, thus my questions.
another 20 would allow me to experiment with spaced Omnis, and
another 30 would allow Blumlein configuration, as well as your
approach suggested above.
thanks for your response,
and please do let me know how I can get copies of your papers.
