Title: Quadraphonic Sound
Post by: coryjiboo on January 08, 2007, 12:19:10 PM
The Disco Biscuits just played NYE in quadraphonic sound.  What would be the best source to capture the show.  Effects would have to come after the soundboard so a sbd copy would not capture everything right?  Would five mics pointing in each corner of the room sound better.  Also would a file that is in 5.1 be a huge file(DVD) or could you mix it to a normal size?  Any help would be appreciated.

the easiest would be to get a quad mic ..the cheapest i've seen is the line audio qm12 www.lineaudio.com

you need at least 4 raw tracks, and mixer for post production. >:D

if you notice at the bottom of the 2 channel mix on archive it says they are working on the 5.1 version, but it might take a while

Schoeps double MS

-small
-easy
-3 tracks
-expensive

But, if you already have 2 cards (or hypers), all you need is an 8, 3 tracks to record on with pre's and a matrix in post.

I wonder if there is a way to set up my c34 to do quadraphonic recording since it has 4 capsules....?

technically, especially with a fixed stereo mic

its picking up front and rear lobes :)

I would think so anyway

a more stereophonic approach would be what george did and split the mics up a bit, the front stereo is like a DIN with a center channel and the rear pickups are facing the back of his stand, in a DIN/ORTF whatever setup he used :)

That makes sense, for some reason I thought quadraphonic referred to 4 channels in a surround config.  I guess Blumlein is just that 4 tracks already phased down to the two.

Exactly what I plan to do in the future - two stereo arrays, 1 forward, 1 back > SD744 - create a 4.0 mix (or 4.1) in Vegas and be off and running. I think quad is the way to go (no need for a center channel - plenty of image from the stereo arrays) - it should be pretty representative of the room you are in (I think)

edit: two m/s arrays would probably be the best bet for mixing in post - more control over the image is never a bad thing

Listen up folks.
All you need to do is add a figure 8 to 2 cards and record on three channels.
You don't need 2 MS or 4 mics or 4 channels or 4 pres, etc.
This is called double MS and it works great.
See above link.....

You could do a 5.1 DVD-A mix.  There's also a way to encode 5.1 as DTS WAV.  It burns to a regular CD-R, just like a regular audio CD.  Just you can't play it in a regular CD player -- it needs a DTS-capable player (generally a DVD player).  My DVD player does DTS audio, but it can't do DVD-A... and DTS WAV sounds just fine :)

I'd like to hear this - thanks george for this effort on a night I couldn't have possibly been able to tape.
