Are you using VVEncode v1.1?  This fixed multiple problems which I
reported.

Also, for the Core Sound style of calibration using IIR files, there's
the older VVTetraVST - Again, you need to use the latest v1.8 which
fixed similar problems.

Re: [Sursound] A-format to B-format Conversion and Calibration Files

[David Pickett]

Pardon my ignorance, but may I ask, for information, about these 
calibration files in the form of IIRs? How do these relate to the 
A-format wavfiles of a first order microphone? Or are they used as a 
means of converting the raw capsule signals into A-format by some 
kind of concatenation, or other algorithm?  What is the relationship 
between IIR files and the .WAV format referred to in the last line below?


Perhaps, because of my ignorance, I am asking the wrong questions and 
maybe all this is written up somewhere; in which case, I should be 
glad to know where I can read about it.


Many thanks!

David

I know about VVEncode; but I am having some problems with it. I 
think these may be down to my PC rather than to VVEncode, which is 
why I would like to try an alternative.


The mic in question is a Brahma, but it was re-calibrated in VVMic format.

A second question: Is there any way to convert calibration files 
from IIR format (as used by VVMic) into .WAV format (as used by 
X-Volver or Brahmavolver) and vice versa?

As I said in the OP, I am experiencing some problems with VVEncode; I think 
these are related to my PC rather than to VVEncode, so i wanted to try an 
alternative. 
My calibration files are IIR files, as work with VVMic. Does X-Volver accept 
those? I assumed it worked only with the wav type calibration files.
Thanks,
Gerard
