Similarly, what does a SoundField mic output? A/B format. Now
translate that into 5.1. That's what's a realistic production flow.
and it does not work very well. nobody who is producing 5.1 the usual
way (i.e. without using a soundfield) will buy what you get out of this
process, and ambisonic lovers who have heard really good renderings of a
soundfield microphone won't be too impressed, either.
on the other hand, if you have a third or even fourth order signal
available, you can apply bruce wiggins' steering magic and get a really
nice 5.1 rendering out of it.
can the FOA fans please stop crying wolf whenever there is talk about
HOA? if you want to listen on FOA systems, that's totally fine with me,
and the music that i record will work ok on such systems.
but if you want to bring ambisonics into the industry, it's either HOA
or go into a quiet corner to die. the argument that any talk of HOA will
be detrimental to ambisonics uptake is sentimental BS. HOA is no black
magic, and six speakers aren't that expensive, either. go try the stuff,
then come back to whine about it.
People are not going to have Eigenmics or stuff like that, and only
some things will be synthesized sounds that can be generated in HOA.
99.999999% of all stereo recordings out on the market are pan-potted
mono with some ambience thrown in, either synthesized or captured with
stereo room mics. this very same production technique can be used with
HOA, drop-in, no questions asked.
with some extra work and a few hoops to jump through, you can do
classical recordings that will combine the advantages of the soundfield
mike with HOA stability. it's no messier than 5.1 or other surround
techniques that are in the market today.
please, guys, HOA is not exclusively owned by the contemporary
electro-acoustic bogeyman that is trying to eat your mahler.
nor does working in HOA imply you have to throw your beloved integrexes
and meridians out. there's a very nice way down from HOA recordings to
FOA rigs, but no real way from FOA productions to HOA rigs (with the
very notable exception of the harpex renderer, which i love, but it's no
excuse for us to keep sitting on our tetrahedral first-order asses for
the next 30 years).
So again, realistic sources and production is going to be B-Format
base, mostly even tossing the Z-axis.
And that's good enough for now.
which is demonstrated most eloquently by the glaring success of
first-order ambisonics, which has been dominating the audio market for
years, as we all know.
ronald, go out there, talk to people in the industry, demonstrate your
FOA systems, get some real-world feedback. been there, done that. try
it, it's very enlightening.
1st OA is something that can be grasped by the average engineer,
recording band member, etc. 1 channel for the mono sound, plus three
differential channels for the X, Y and Z axes. That's about as
intuitive as it gets without being totally wrong. Now try to explain
HOA to your average musician. Haha! You really think HOA is going to
take off if the average garage band member can't wrap their head
around it?
it's not really any more difficult. any recording hobbyist who can grasp
M/S stereo can grasp arbitrary order ambisonics, at least on the same
level that your average sound engineer has an understanding of how
stereo works.
this is no longer an argument, this is xenophobia.
i have written HOA tutorials so simplistic that i fear some
mathematicians are crying for blood.
So if the Ambi-Snobs could come back from their space mission and set
foot on the ground for a while, then 1stOA actually would have a
chance.
yeah, right. we screwed up :)
Once 1st OA is as widely used as stereo is today, THEN it's time to
push further. One doesn't feed a baby with a steak!
hmmm. the problem is that your baby has wrinkles and whitish whiskers
(plus, it seems, a stiff upper lip), so maybe it's time to acquaint it
with ale and beef.
there's a time in life when breast-feeding, for all its evident joys and
advantages, does become kind of awkward. at the age of 35, i'm happy to
have moved on :)
