Hi Brian, Aaron,=0D

I hope /expect the underneath to be to-topic:=0D
=0D
Although not able to confer head-motion dynamics as ambiosonics promises, =
in my experience, employing properly recorded environmental sounds (so with=
the right ITDs and ILDs recorded (eg pinnaeless dummy heads, jecklin disks=
et cet)), when combined with the Ambiophonics Institute=92s (Not Ambisonic=
s!) (google) or BACCH cross-talk elimination of the replay end of things (=
speakers), brings truly believable (you are there) sound reproduction with=
in the realm of current hobbyists/sound recordists and music lovers workflo=
ws.=0D
Especially when (front-rear) baffled spaced stereo miking set-ups are used.=
And combined with 2-frontal and two-rear speaker replay systems. So 4-tra=
ck recording & replay. So if enjoying real-life (3D) natural sound reproduc=
tion (and recordings) is what you are after, have Google at Ambiophonics.=
=0D
Truly remarkable stuf.=0D
You (all) should try.=0D
Apart four-track recorder (not strictly needed but much nicer than=94just=
=94 2-channel capture) and a little adaptation of speaker arrangement (and/=
or an extra rear set) and some free software or minor hardware investment, =
will get you going.=0D
I think you will be satisfied. And intrigued by the amazing revelation of =
the space information that is contained in proper stereo recordings (inclu=
ding your music libraries!). Cross-talk of speakers in stereo set-ups or th=
e elimination of your pinnae in the hearing experience during headphone-l=
istening cripples our auditory ear-brain system in its abillity to reconsti=
tue a proper soundstage.=0D
=0D
It=92s =93discovery=94 and implementation has transformed my sound recordin=
g approach and hightened my listening enjoyment no end.=0D
=0D
Hope this addresses your question somewhat.=0D
Ok?=0D

Hi Brian,=0D
=0D
I got excited at the prospect of taking an Ambisonics mic into the field to=
do the kind of 'anthropogenic'-centric soundscape recording I've done lots=
of using near-binaural mics (and some Blumlein and M/S and spaced omni).=
=0D
=0D
The tantalizing prospect was to take composed immersive sound to the next l=
evel, allowing and playing with, as you say, listener head position=96espec=
ially since platforms like YouTube and Facebook support headset decode and =
have some rudimentary HRTF synthesis...=0D
=0D
....long story short, my enthusiasm cooled significantly when I played with=
live-decode from recordings made with second-generation tetrahedral ambiso=
nics, because for people used to 'rich' stereo with a lot of subtle cues fo=
r e.g. depth and focused localization, the stereo image produced felt very =
vague and flat=96more like an uneven flat sphere than a three dimensional s=
pace, as it were.=0D
=0D
>From what I understand higher-order Ambisonics fills in the 'holes' and giv=
es more, but IMO what's going to be really necessary for the technique to w=
ork as I want is to somehow capture, and be able to "remove in post" the ti=
ming and maybe to some extent frequency variation characteristic of HRTF, a=
nd synthesize more accurately those differences for the realtime-rendered h=
ead position.=0D
=0D
I have vague ideas of how one might in theory attempt this, there should be=
enough information in a tetrahedral array=96and there should be ways of e.=
g. using a nested double tetrahedral array at controlled spacing, maybe wit=
h the inner set serving as an occluding baffle...=0D
=0D
....but that would require a lot of computation if it worked at all...=0D
=0D
....and I'm too lazy personally to take it on. So far.=0D
=0D
But absent some kind of next-generation step up, I am myself waiting for mo=
re to be there before jumping... :/=0D

Hi all,=0D
=0D
Is anyone experimenting or working with ambisonic audio?=0D
=0D
I see new VR microphones out there, Zoom just released a 360 mic for around=
$350=0D
=0D
I=92ve always been a fan of and recorded ambient, but I really love the ide=
a of putting on headphones and as the you move your head, the audio moves a=
ccordingly so it=92s as though you were really there=0D
=0D
=0D
I just haven=92t seen much in the way of standalone ambisonic audio or head=
phones for that purposes.=0D
