About

VVAudio

VVAudio started around 2001 when David McGriffy recorded the Reno Air Races with a SoundField microphone and went looking for software for processing the results. Angelo Farina had a bit of Fortran code on his web site for deriving virtual microphones from B-format. David rewrote it in C++, added a visual interface and Visual Virtual Mic was born. Thus VVAudio was in the ambisonic decoder business.

Then in 2007, Core Sound began developing its TetraMic and looking for software to support it. VVAudio worked with Len Moskowitz and Richard Lee to develop a calibration process and a signal chain to implement the results. Thus VVAudio got into the encoder business.

Over the last several years, VVAudio has been investigating higher order ambisonics and parametric techniques. While HOA is clearly starting to be a useful tool, it also became clear that we haven't nearly done first order right yet. At a minimum, we believe that this means encode, decode, rotate, and pan available for all the important platforms. VVEncode is the first release towards this end.

Here's a timeline of VVAudio's releases

  • 2001 - Visual Virtual Mic
  • 2005 - VVMicVST
  • 2007 - VVMic for TetraMic
  • 2008 - VVTetraVST
  • 2009 - parametric and HOA
  • 2013 - VVSDK
  • 2015 - VVEncode

David McGriffy

David McGriffy is VVAudio's principle inventor, programmer, and just about everything else. He has been recording music since he could press the record button on his father's stereo and been programming computers nearly as long. Add a degree in math, stir well, and you have ambisonics. While working on audio code, David has also held many varied jobs in the computer industry, from startups to government and natural foods to oil rigs, this last leading to a patent for a vibration analysis system.
