Thanks very much. You are so kind. I will have a try as your suggestion.

Do let us know with what results !
These type of problems are usually a
You can make a velocity microphone by subtracting two closely spaced omnis. I
saw a paper on making ambisonic recordings like this a couple of years ago:

The problems, though, are spatial aliasing at high frequencies and lack of
sensitivity at low

Without more details, it hard to speculate about problems, but I'll note
that subtracting the outputs of two omnis to get a fig-8 response will
result in a frequency response that rises 6dB/octave with a 90 degree phase
shift relative to the sum. Unless that is corrected, these signals are not
