1
3D Virtual Microphone System employing an High Order Ambisonics Microphone Array
2
The origin of a new multichannel shooting and recording system
  • The project was started by Rai Research Centre and Advanced Industrial Design in Acoustic (A.I.D.A.), spin-off of the University of Parma, in 2009


  • It resulted in the patent of an innovative system for live shooting and recording, called 3D Virtual Microphone System


  • Starting from a sperical microphone probe, the system can synthesize up to 7 virtual microphones, which can be moved in realtime, with variable directivity (zooming) capability
