First VVTetraVST converts the mic signals to B-Format. I write the Windows and Mac software for the TetraMic. Of course, depending on your application, budget, etc. The Core TetraMic, is frankly, dirt cheap, a real bargain, however, most of my work is critical classical and any noise is unacceptable, regardless of how nice it may or may not sound, hence I would elect to spend the extra money on a full blown Soundfield. I made inquiries about the Holophone mic and was sent a demo DVD, to be frank, it wasn't great and some of the samples had distortion so I wouldn't recommend that from my experience. He is now using the DPA which he is very impressed with. Mike Skeet, who is a friend of mine used the ST350 and found that to be excellent, however, he had issues with the gain structure of the control box. I've also heard a Soundfield demo recorded at a football match which was to say the least impressive. I've used a newer Soundfield mic with the surround processor and can honestly say that it was impressive. The originals had a reputation for being slightly noisy (as far as I am aware they used the same capsules that the original calrec stick mic's, which were not, IMHO, the greatest mic's of their type around at the time). I've used several Calrec/AMS/Soundfield systems over the years.

I'm not dissing the TetraMic, for those wanting to experience the remarkable possibilities of Ambisonic's, surround from a single point microphone/microphone system it's a bargain.Ī few points I'd like to make as to where I stand on the issues. I think my comments have been a little miss-interpreted.

Some of the other comments may also interest you. You might have a look at what Richard Lee, one of the original Calrec Soundfield designers, had to say about TetraMic on the user comment page:
