Thanks Gerard
I thought I would wait for the discussion to complete before I piped in, as the builder of “Brahma-in-Zoom” microphone. Zoom provides firmware which creates a B format signal from their microphones, without height. But my issue has always been the odd arrangement of the capsules – front pair is XY, and the rear is MS, with a figure of eight sideways and a cardioid facing front. Brahma-in-Zoom removes the original capsules and replaces it with a true tetrahedral array of 14 mm capsules. The microphone is then calibrated to produce a set of filtermatrix files. All recordings have to be processed with this matrix (Using Brahmavolver, X-Volver or VVencode) to produce B format recordings. There is now also a version with an array of 25 mm capsules mounted on top of the Zoom H2N and I am pleased with the results. This too is sold with calibration files. In fact, none of the microphones I sell are without calibration. There are a couple of second order designs I have built, but I am waiting on good and reliable calibration systems. Next week I will complete an all digital second order microphone, outputting to USB. umashankar Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10 ________________________________ From: Sursound <sursound-boun...@music.vt.edu> on behalf of Gerard Lardner <glard...@iol.ie> Sent: Tuesday, April 10, 2018 5:01:07 AM To: sursound@music.vt.edu Subject: Re: [Sursound] [allowed] Re: ***UNCHECKED*** Zoom H2N - thoughts?
