Done this before with Davinci Resolve.

Go into Davinci Resolve and select the 6th tab at the bottom called "Fairlight". It is a audio editor. Then there is volume controls on the bottom right that say audio 1, audio 2 and bus 1. Select the volume control on audio 1 and increase it. Go to the last tab in Davinci Resolve and select "Delivery". Then name the file. Select "add to render queue" at the bottom of where you saved the file name or right hand side at bottom of Davinci Resolve. Then select "render all" in upper right hand corner of Davinci Resolve. Done!

If you have problems PM me and will figure it out.

Here, at last, is my YouTube review, which includes a range of audio samples.  My YouTube channel is not monetized so including this link doesn't make me any money - sadly!

As for audio surveillance - it is actually large compared with most wireless mics.  But for discreet recording of music events, it's indeed the smallest 32 bit float stereo multi-mic recording device.  In the video I did include some ambient recordings in a takeaway cafe and in a supermarket, but nothing the mic heard would not be heard by anyone else there.

Obviously there are many factors involved but in the video I did comment that compared to the Instamic, the Mic Pro does record 32 bit float stereo, has twice the memory, and twice the battery - and costs half the price.  But I don't think it's waterproof!

I'm not sure if this was posted before but Panasonic released the zs300! 15 times zoom 1 inch cencor. If this thing can be hacked to film continuously like the zs100 can, it will be perfect for concerts!

Thanks. I'll try resolve....

Thanks for these reports Peter.  These little devices and others like them are quite interesting and promising.  Especially interesting to me at a fundamental level is how they enable modification of pickup pattern and stereo recording.  I'm interested in finding out how well they are able to do those things such as how accurate the shape of the derived sensitivity patterns across a wide frequency range.

- According to AI search, this device uses MEMS mics and associated techniques to obtain stereo recording from closely spaced omni mics.  I can't find where AI might be getting that info from, but the features of the mic do strongly suggest that it is indeed a MEMS device.

- If the device is set to record 32 bit float stereo internally, then you can't record it with any of the built in 'effects'.  It's just the pure stereo thing, which is fine.  If you set it to mono, and ask it to record that with processing, then you can set the mic array to record internally as if it was omni, cardioid, fig of 8, or narrow.  I've tried cardioid so far, and it certainly rejects the sides and back.  Now whether these settings would allow a pair of these to be used as a pair of cardioids or omnis instead of just one for single point stereo I'm not sure, in terms of how good the result would be.  But it's possible on the face of it.  Maybe one could even create an MS pair with one set to cardioid and the other to fig of 8.

I am almost certain that the mic array is actually the same as that on the Instamic.  The front facing mic aperture is quite wide, allowing space for more than one of those little MEMS devices.  The supplied windshield covers those mics and not the side ones, probably because if the side mics supply the stereo content, those using the mic just for transmitting audio to the receiver do not need to use those side mics.  They only come into place for recording 32 bit float stereo.  But the front mic, or mics, is used for creating various polar patterns, which I believe is what you can do with (say) 4 MEMS capsules.  So it really is a direct competitor with the Instamic.

As far as I'm aware, all individual MEMS elements are omnidirectional monophonic devices, and it's the combination of more than one of them in a single device along with sum/difference/phase-processing provides potential for lower noise and/or control of polar pattern. That implies that our discussion about using a pair of miniature omnis to produce a fig-8 sensitivity pattern (for use as a Side channel) or other patterns as speculated about a year ago in the Omnis to figure of eight thread may have somewhat more merit than originally received.  I've put off the experiments I intended to do with two closely spaced / somewhat baffled omnis in combination with phase-rotation processing afterward, but am now thinking of returning it it.
