Re: [Sursound] [allowed] Re: A-format to B-format Conversion and Calibration Files
It works! The User Interface is not as slick as VVEncode, but it works in Reaper. Likewise, Visual Virtual Mic (VST) and ATK FOA Decode Stereo (JS) both worked in place of VVDecode.

Re: [Sursound] [allowed] Re: A-format to B-format Conversion and Calibration Files
Hi David, I'm not really the right person to answer your question, but maybe this page: http://www.angelofarina.it/Public/B-format/A2B-conversion/A2B-Xvolver.htm and some of the links off it will help. The "virtual microphone" paper referenced about a third of the way down gives more detail.

Re: [Sursound] Open-source Spatial Audio VST library - SPARTA
Thank you Leo! For some reason the link to the Binauraliser zip (OSX) returns 404... Everything else seems to be working though. Cheers!

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

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