Not at all! You can decode an Ambisonic mic to a stereo array that has a 360-degree acceptance angle (back to back cardioids). Or you can decode it to multiple spot mics pointing at the individual musicians, and pan those as you like.

OK, I see. Thanks.

This was what I got from the article and what is making me seriously think about saving up some shekels. I really like the idea of this flexibility. Thanks for that, Sam.

It also allows you to virtually remove that one player with bad timing or an out-of tune instrument from the mix. ;)

Apart from the fact that I could never justify spending that sort of money on a microphone - huge fan that I am of Rode and their works - for my music recording work it would always be hugely compromised.

Most of my music work (ie 95%+) these days is location recording of live concerts with an audience present. I'm increasingly finding that more and more restrictions are being imposed on me - always in a friendly and polite way - about where mics and stand may be placed. In many cases simply having the mics in view is frowned upon. For all intents and purposes stands have to be invisible. On one occasion in the last year the last-minute demands on mic placement were so extreme that I had to simply pack-up and leave... no point wasting my time and energy attempting to produce a fatally-flawed recording.

So brilliant though the Rode would be I'd never be able to place it satisfactorily. I know it's only 'one' mic... but even a single stereo-pair is frowned on by some.... widely-spaced omnis is often the best deal that I can reach.

Yes. It's a hugely frustrating situation, often down to total misunderstandings of H&S requirements from people more interested in protecting their backs than understanding the law, or even applying common sense!

Yes, I've had that too. Told I had to set the mics up at the back of the church, so after patiently explaining the nonsense of that request and getting nowhere I packed up and came home.

On a slightly more amusing occasion I was told that "as it was such lovely weather they were going to do the concert outside instead". I did have a stab at that with a pair of spaced MKH20s omnis (being the mics with the lowest susceptibility to wind noise that I had with me), purely as an experiment and not expecting it to work...

...and lo, in the few sections where the inevitably horrendous wind noise wasn't obliterating the choir, the adjacent main road traffic noise was... And when I sent them the file out of courtesy they complained about the quality of my recording! :headbang: :x

The only way to overcome the mic-stand phobics is to fly the mics on catenary wires, like what the pros mostly do... but the cost of the appropriate hardware and the H&S requirements involved in that is massively worse, let alone the far greater rig/derig times. And that's assuming the building has appropriate and accessible mounting points anyway... which few do!

How quiet do drones get nowadays? And how much wind shielding would you need to protect from their own wind noise?
Asking from a purely hypothetical stance of course.

[EDIT - floral stands sounds a lot more practical!]

Hmmmmmm........ I wonder if the concept of "Dirigible mic stands" has legs (we'll probably not legs but you know what I mean) :thumbup:

The sadness is that these are genuinely pleasant people I'm dealing with. It's just that they have zero understanding of the recording process. I've also had it said that they've seen choirs on t'telly with no mics visible at all... not realising of course that what they saw and what they heard were in two different timeframes which had been overlaid...

Ho hum! :)

Of course, and there's no reason they should know about the recording process... but you'd think they'd listen to the advice of someone who does!

I've also had it said that they've seen choirs on t'telly with no mics visible at all... not realising of course that what they saw and what they heard were in two different timeframes which had been overlaid...

...or via slung mics carefully positioned out of shot. The slung Schoeps mics for The Proms at the RAH are almost invisible to the naked eye, let alone the cameras!

I am definitely interested in this mic for surround recordings (I typically use a pair of ORTFs), but I'm struggling to understand its usage as a stereo mic beyond simply muting a pair of capsules?

The idea is that you can create your own pattern microphone, you don't simply mute two mics. So you can bring the included area in tighter, or widen it after recording, whereas with a stereo pair, you are stuck with what you've got. Which if you are experienced, probably isn't a problem, but there may still be times when you might want to reduce the ambient/audience/background noise.

I still don't really get it. Maybe the subject of a one/two-pager in the mag, Hugh?
