A primary specification and constraint of any tetrahedral arrangement ambisonic microphone is how close together the capsules are, measured by the radius of an imaginary sphere tangential to all  four capsule diaphragm faces.

The closer together the diaphragms, the better the microphone will behave at high frequencies.  Above a threshold defined by that dimension (corresponding to frequency wavelength) the matrixing breaks down and the virtual polar patterns go wonky and get pretty ugly.

I don't see that specified for the H3-VR, but it will be sure to be checked and reported in any truly serious review.  That said, given the market target I mostly expect more superficial reviews that basically report on how easy it is to use and how ambisonics is cool, and expect most of those reviewers to be completely unaware of this important specification and it's implications.

All in all, its a a very cool device at an attractive price.  Kudos Zoom.

One of these and a chin strap and you are stealthing VR goodness FOB ...



Seriously though I may get one of these. For the price it would be cool just to play around with and if I don't like it I can give it to the Marketing Manager at work so he can create VR content for our website. I work at a university so anything we can do that's cool and trendy makes us look better. Seems from a brief look that it can be vertically or end address? I thought one of the selling points of ambisonics is that you can point it any direction later...

Also this - "Staying out of the shot can be tricky when recording a 360-degree video, which is why the H3 Control App lets you remotely access transport controls, level settings, and metadata notes right from your iOS device.*

Part of the all-in-one simplifying innovation of the thing is that it incorporates a "which way is up" sensor. It knows how the device is oriented and allows it to automatically accommodate for vertical right-side-up or vertical inverted, or end-address right-side-up or end-address inverted. 

Beyond that, yes, with full-sphere ambisonics you can manually re-orient the virtual orientation however you like.

But simply automatically reconfiguring the matrixing to accommodate for mic orientation and making that invisible to the user represents a significant reduction in complexity and user error.

I agree with everything you say, Gutbucket, and bow deeply to your knowledg of the subject - personally I never got beyond MS stereo in terms of complexity!  However, I still feel that the device will sink or swim based on capsule quality - indeed we have to remember the price point but, apart from everything else on offer, the truly unique aspect of this device compared with every other compact recorder on the market is that it has no inputs of any sort.  (In the nature of the thing, that's inevitable).

Almost everyone here seems to regard the built in mics of the devices we discuss as being something to be used when all else fails - we have our own favourite external mic rigs to use with our recorders - but this time, it's the internals or nothing.

It's advertised here in Australia for pre-order - I'm really hoping the reviews will be positive because I need a really, really good excuse to invest in one of these given that I have no particular use case, these days!  But I want one....

At risk of posting what everyone already knows....

Got mine today.  I hope to try out the mics Friday just to see how they sound on piano, the ambisonics stuff will have to wait.  The Zoom Ambisonics player can only be downloaded for Mac now, I got an answer back fast from Zoom on that:

"The Zoom Ambisonics Player will be available for Windows this month (November). Unfortunately we do not currently have a more specific timeline."


There is a Quick Start guide, but you have to print out your own operator manual from the Zoom website (119 pages), same for the Ambisonic Player software manual (27 pages).  This may be an inexpensive device, but the price per ounce is rather high, this is a comically small package (that's good).

If you can save the files onto your computer in B format you could use pretty much any ambisonic software/plugin to process it.

Rveryone who wants to know about how to stealth tape — you put this on the top of your head and try to act natural. That’s all you need right there!

Noted one placed mid-orchestra about a month ago at a late-night syphonic event were audience seating was removed so that the patrons could wander freely about the hall, including around a semi-circular path through the orchestra.

I bought one to play with but haven't really put it through it's paces yet. I got a decent discount and it came with a dead rat windscreen that is meant to be used with the factory foam windscreen. For me it is basically a toy.

Has anyone here used one of these to record a show? I'm considering getting one to just plop on a table, shelf or stagelip when I don't feel like setting up my actual rig. The internals on my PMD620 aren't terrible but they aren't very good either.

Any links to a show recording or actual field experience with loud music (as opposed to chamber music or nature sounds) would be very much apreciated!

Ok, so I pulled the trigger.   Found a very reasonably priced one on eBay.    And while I don't record concerts much any more, I do still record my bands and practices..., so I'm expecting really good things from this in that small setting w/the instruments placed all around it.
I'll post some samples in a couple weeks once I have it, learn how to use it...and actually employ it.

Proper scope.   I'm a small guy and have hands slightly larger than Trumps.
sort of makes you revisit that funny hat idea.   >:D
