Re: [Sursound] Looking for a very, very old thread - mics pointing inwards?

2013-03-04 Thread Eero Aro

I'd be interested if you do turn up a reference.


The setup is used by some people I know. It works, if used carefully and
properly. Sorry, no references to point to.


maybe it was in Resolution
magazine.  I thought I'd kept the article, but I can/t find it in my file,
and there doesn't seem to be anything on the web.  Maybe that's what you're
thinking of?


There have been some articles in Sound On Sound about somewhat similar
subjects. However, these are not what I am looking for.

I'm still confused as to what is being described.  Could it possibly be this?

Sorry Eric. I have never seen that article before.

Originally I was looking for a possible follow-up to this short thread,
that was started by Etienne in Nov 2002: You can find it in Sursound
Archives.

The idea is a live performance in surround, where the performer is a
mouse in a shoe box. The box is made of some resonant material.

The mic / speaker layout is inverted ... i.e. the mics are just
outside the box, pointing in, through little holes.  The listener is
aurally inside the box hearing the mouse walk around them..
 just straight mic channel to speaker ..with 6 or 8 standard
cardiod mics / speakers.

Etienne only got two replies to his post. Maybe that was it.
I suggest we move on to something completely different.

Yes, I also found that post, but it isn't quite what I was
looking for. Maybe my imagination is just making up things.

Hi

Are you thinking of the arrangement that one of the audiophile record
companies use? Near coincident fig 8's plus an omni pointing in.

Every Blessing

No. I am writing an article about an un-orthodox stereo recording setup,
common acoustical point. Two cardioids with a reasonably long spacing,
pointing towards a single source, so that the on axis directions cross.

The setup works and has some advantages compared to mono miking and
it works well with single instruments and in a reasonably anechoic recording
space. But as you see, it isn't a stereo recording setup as such. It's more
like a twin mono miking setup. You need to be careful not to create comb
filtering.

The setup reminded me of a discussion of a similar type surround recording
setup. Four or several mics on a circle around the source would capture a
LOT more time and phase differences between the channels than a stereo
setup.

Hi

Not come across that one!  I often use ORTF stereo set-ups, especially if I
don't want the pin point accuracy of Blumhein.  I'd be interested if you do
turn up a reference.  I've used the Faulkner array of spaced figure of
eights with some success.  I did read that he'd more recently added further
mics - I can't remember/find the ref. now - maybe it was in Resolution
magazine.  I thought I'd kept the article, but I can/t find it in my file,
and there doesn't seem to be anything on the web.  Maybe that's what you're

[Sursound] Looking for a very, very old thread - mics pointing inwards?

2013-03-01 Thread Eero Aro

Hi All

I have been spending some time looking for a thread that I think
we had ages ago about a surround sound microphone setup,
in which the microphones would not be pointing outwards from a
point, but inwards.

Is there  anyone who would remember that thread? I only found three
posts of a short thread started by Etienne on Nov 14 2002.

Somehow I feel like there has also been another more lively
discussion about a similar subject. Maybe I just don't find the right
words for my search in the Archive.

interesting. i would have stacked them, for perfect horizontal coincidence.
if used like this, does the array require correction filters?
and isn't it a problem that frontal sound hits the front microphone
after the rear ones, or can it be corrected?
if it can be corrected, why aren't we all using four schoeps or b+k
cardioids in an inverted tetrahedron, i.e. pointing inwards?

Perhaps not old enough ...
