I bet they'll sell a ton of these, though I doubt many tapers will be buying them.

I always thought of the H2N as "a mic that records" but in this case, there is no other way of describing it.  The whole point of the device is the mic array and the processing behind it.  So, it will sink or swim according to the quality of those mics.  The device has no point if the mics are not adequate.  Right now I am not seeing any info about the specs of the mics.  It's very likely that we will know nothing about them till the reviews are in.  So personally I wouldn't dream of pre-ordering.

What gives me cause for optimism is that they could use capsules with some deficiences but remedy those deficiences in the following electronics, given that the capsules are going to be used with the device and nothing else.

On the other hand, for myself, I don't hear a significant difference in built in mic quality between the H1N, H2, and H2N.  Will the H3 use H1N capsules, but just twice as many, or something completely new?  Lack of any mention in the blurb (that I have read) about mic quality makes me wonder.  It would have been nice to have read something about "newly developed mic capsules" or the like.

Well said. I agree (read: FINGERS CROSSED).

My point exactly - without specs relating to actual mic quality, the rest is of academic interest.  We simply don't know whether this will be crap or amazing.

I expect it will be amazingly crappy.   
honestly,  I bet it will be cool sounding in terms of what you can "carve" out of a recording, but the sonic characteristics will be that of typical cheap china caps.   brassy and shrill.

I'm with Nick in that I don't think the quality of the microphones is the main thing of importance here, and see that as rather quite secondary, as it must be to keep the cost reasonable. The "all in one", simple to use nature of the device is its primary feature and the main attraction.  The key is the array being directly linked to the recorder and it's built-in ambisonic processing.  This opens up ambisonics to a new and much larger audience than recording geeks, acousticians, and academics.

The primary value here is that all the PITA ambisonic stuff is taken care of internally, relieving the recordist of the biggest burdens of recording ambisonically.  No 4ch wiring harnesses or clunky power supplies for each capsule. No need to match gains perfectly across all channels on a multichannel recorder and maintain that match while changing gain during a recording session.  No need to correctly sequence the resulting files when importing them into a format conversion app.  No need for an app at all to get usable output, although that functionality is available for greater flexibility and post manipulation than what one can do direct out of the device.

Because of all that, I see this particular move to "all in one" as a far bigger deal for ambisonics than the "all in one" shift away from external preamps and ADC's in the taping world a decade ago.  That was mostly about increased convenience, simplicity, and weight without taking too big a hit on quality.  This is about tapping into a new customer market entirely.  Serious users will likely stick with other ambisonic mics for now, but this type of implementation is the future IMO.

What gives me cause for optimism is that they could use capsules with some deficiencies but remedy those deficiences in the following electronics, given that the capsules are going to be used with the device and nothing else.

Yes.  That's one advantage the TetraMic has over its competition- the use of corrective filtering specific to the particular microphone.  Presumably other A-format output ambisonic mics also do correction specific to the capsule configuration geometry within their A-format conversion apps, but the TetraMic is the only one I'm aware of which also corrects for the specific response of each capsule, using a correction file linked the microphone's serial number.

All that could be employed within this device, but I doubt it.  We won't be privy to all that secret sauce, but my suspicion is that this device will correct generically but not specifically- that is to say, I think they will optimize for the dimensions of the tetrahedral configuration and apply average response corrections for the microphone capsules used, but will not correct for specific response variations between individual capsules.  That would be too costly to do for each mic at this price point.

This does address the biggest hassles I have running TetraMic though.  For years I've been thinking of having a small custom 4-channel mic-power-supply/ganged-preamp built so that I could attach the TetraMic, preamp and a DR2d together as a single compact unit.  This recognizes that impulse and implements it nicely.
