Oddball microphone technique (OMT) - part 2
Gutbucket:
Continuation from the original thread here- http://taperssection.com/index.php?topic=96009.msg1279052#msg1279052
DANG! OMT with the sideways supercards angled forward +/-45 degrees most certainly works in a small club (a good sounding one at least) as long as you can manage to shoe-horn it in there and keep everyone happy. So good in fact I plan to play with angling those sideways facing supers forward outdoors to see if it works equally well everywhere. I'll definitely be revising the OMT suggestion for small rooms (crappy ones remain to be tested, but I'm not overly motivated to explore that front). Listening today to last night's recording directly off the DR-680 via headphones using the 680's internal monitoring mixer I prefer not doing the Mid/Side mixing thing with the rear facing channel when the spaced +/-45 degree supercards are also in use, but rather just bringing it channel up with the appropriate level, panned to center. Played back in surround with all six channels feeding their own speakers (no mixing, just mult'ing the single rear-facing microphone channel to two back speakers, omnis routed to the side surrounds and sub) the way it handles audience chatter and room sound is really impressive. All that is there, more of it in fact compared to the 2ch stereo mix, but the separation of it from the main stuff in front actually improves clarity of the vocalist and on-stage stuff and makes it easier to hear around the elements which would otherwise be distracting and cluttering. I'll certainly be exploring this angle more.

I provided an audio patch out to the music club's regular video taper this past weekend while trying out 6ch OMT in a small club. Below are links to a couple YouTube clips he's posted which will give some idea of baseline performance in this kind of situation.
Caveats!- Audio here is a raw 6ch>2ch monitor mix made on-the-fly out of the DR-680. No listening was done, much less proper balancing, EQ or any other post production. Balance, mix levels and panning of the 6 OMT microphone channels were simply a best guess. Deep omni bass content overloads the input of the small video recorder at times. Subjected to video recorder's file compression and of course YouTube data compression, yada, yada & hand-waving.. At least it's something to give you all a taste of what OMT can do in a small club. Unfortunately the video taper didn't run for Mingo Fishtrap which was the best sounding set of the weekend after Bettye LaVette, and of an entirely different genre (full NOLA-ish band with funky organ & horn section). Recording location was from the same column the video cam is mounted to. It's hard to tell from the video, but that's basically the far left side of the room, in-line with the left PA, about 15' away from the stage.

Thanks a lot for sending your recordings. Rocksuitcase, it is great to have your OMT and Kindms's single pair for comparison. Overall I prefer the OMT version, there is great sense of space. And I like the warm sound on Kindms recording. But maybe that is possible to tune it on OMT by an equalizer.
Gutbucket, you have my big respect for a 6ch on-the-fly mix. It is a very pleasant listening. I'm surprised that it sounds so spatially even when you were close to the left PA. How much did you space supercards?

The kicker about the comparison is the room itself is typically difficult to get good vocals on an AUD recording. Toad's place is basically a rectangular width room with the stage in the middle against one long wall with the soundbooth, hence mic stand location being about 40 feet from the stacks, again centered in the rectangle. When I would run with Blues Traveler's permission, I would run up in the crows nest, which is where Matt set up his official streaming/recording cameras along with the SBD feed into them. So, to read that the OMT has "great sense of space" makes me truly smile as this is the characteristic most missing from other recordings in there. Also, when you like the warmth of the ck1x recording, that tells me those mics worked well with his SD pre-amp. I agree with your assessment as well, the OMT is more "realistic" while the ck1x has nice warmth if maybe a bit boomy in the low frequencies.
