i could imagine way worse things than being called a MAG fanboy. there
has been very constructive discussion in the past about why
first-order works way better than it obviously should, and what its
limits are. this exchange however doesn't quite cut it in the
"constructive" department.
So how does this 'human energy-vector-detector" work then?
ok'ish.
ppps How are higher-order microphones coming aloing these days, or are
we still happy truncating the infinite series at one order above an
omni?
higher order microphones work in principle, but are nowhere near as
pleasant as simpler stereo microphones. in addition to coloration
problems, they suffer from noise problems due to the high gains required.
What you need is a 'virtual' high-order microphone.
the approach i'm exploring is this:
http://stackingdwarves.net/public_stuff/linux_audio/tmt10/TMT2010_J%c3%b6rn_Nettingsmeier-Higher_order_Ambisonics.pdf
skip the intro and jump to section 5.
i used to think that this kind of hack is not really conceptually
elegant (it isn't - nothing beats the simple beauty of a sound field
microphone). but then i learned about all the unholy hacks that are
routinely being employed by respected record labels to produce their
(very nice sounding) surround recordings. i have been very relaxed about
conceptual purity ever since.
but for my work, i still want to have a plausible theory first and then
see what can be done in practice. i dislike stuff that "sounds nice"
whose proponents can't really explain why :) but that's a personal
spleen of mine, not a snide remark at xtc in general.
best,
