Actually I've managed to find a picture of a Mercury capsule complete with astronaut. I rest my case.

I think you'll find that if you reset the LUFS to -15, switch off the HPF and then normalize to -0.5dB all will be well....

Morning chaps!

Just FYI, I've been in touch with Zoom about getting the H3-VR in for review. Will report back when I hear more...

Thank you young sir!

A request: Whoever reviews can they can the measurement tools out to establish things like noise-floor, freq response. end-end S/N ratio etc?

I thenk yew!

If I understand correctly, in a typical stereo music application, outside the VR/surround, the signal can be decoded as any number of mono/stereo mics in any coincident configuration, pointing in any direction.

Taking a familiar scenario of a singing guitarist, you could place the mic in a suitable position, take the signals and decode them as a mono cardioid (or hyper, or fig8 or whatever you want) spot mic pointing at the guitar. You could then take another copy of the signals and decode them as another cardioid (or whatever) mic pointing at the singer's mouth. As the signal originate from the same point in space, phase issues will be minimal - you couldn't really achieve that coincidence between guitar and vocal spot mic any other way (this does of course depend on finding an optimal single position for the mic)


You can apply this to any scenario - from a single NT-SF1 you could decode a main stereo array as well as any number of mono spot mics pointing in any direction.


That's my understanding anyway, and I have to say it is appealing, especially for the singing guitarist scenario. I may well have it all wrong, of course.

That's my understanding too, and it's appealing to me for recording choirs, sessions and the like where I can decode into, say, a stereo track for the ensemble and separate mono tracks focussed on soloists etc. The surround sound possibilities aren't of interest to me now but who knows what might come down the line once I have the capability.

Bear in mind that all these separately decoded and aimed soloist mics you're envisaging are inherently coincident with the main stereo pair. So while you can narrow the polar patterns of these 'soloist' mics to improve (slightly) the selectivity and reduce spill, they aren't physically any closer to the sources so the direct/reflected balance doesn't change as much and the focussing effect isn't quite the same as a more conventional accent or spot mic placed in close. It's a useful facility, certainly, but rather different to what you might be used to.

OK, fair comment. You don't get anything for free. I'll bear it in mind. In the sort of context I'm thinking of I think t should still give me what I want as a way of emphasising, shall we say, an area containing a particular soloist that I can then use in the final mix. Anyway, we shall see.

In the meantime here's a review from someone on Amazon called Mr C (nothing to do with me, I hasten to add) who sounds as if they know what they're talking about:

(3 stars) Don't expect miracles

On the face of it, this item was a dream - a combination of the ambisonic microphone, the recorder and the ability to produce output files in several formats. In reality it leaves quite a bit to be desired. (This shouldn't come as a surprise given the price point). I have several other Zoom products, and I've always found build quality to be excellent. Not so with this device unfortunately. Plastic feels cheap, controls are fiddly (as the device is a lot smaller than it looks on photos) and the overall feeling is that this has been produced a price - which I suppose, in fairness, it has.

I could live with all of this, but the audio quality was not what I had expected. My desired use was to produce 5.1 output to use with video. Fed the ambisonic A format file through Zoom's desktop software and sure enough, a 6 channel wav emerged. However, it was very poor quality in comparison to what I recorded at the same time using an on camera 4 channel microphone setup (this was built into an old Sony camera, not an external attachment). Output sounded very vague in terms of direction (which is bizarre given that this is an ambisonic device) and high frequency response was just plain dire.

I think if you were using this for recording a VR soundtrack it might be ok - if you're expecting good quality 5.1 from it as the end result, you'll be disappointed.

On the plus side, battery life was excellent - just using plain alkalines.

I think half the problem is that I am used to Zoom producing products which punch significantly over their weight - and this one, for once, just doesn't.....
