Core Sound TetraMic:tm: 1st-order Ambisonic Microphone In Stock Now

The first portable, single point, stereo & surround sound Ambisonic sound field microphone to be available for under $900 fully configured for most multi-track recorders and audio interfaces. Individually calibrated, each TetraMic is the finest performing microphone of its type in the world.

Each and every TetraMic is individually calibrated and comes with its own calibration files. All other first-order ambisonic mic from major manufacturers use a single generic calibration file for all of their microphones.

Based on the principles of Ambisonic recording developed by Michael Gerzon and Peter Craven during the 1970's, TetraMic allows you to place a single exceedingly accurate tetrahedral microphone in a sound field, record four channels of audio in "A" format, transform them using software into "B" format (W, X, Y and Z), and later interpret those four channels to essentially any single-point configuration of microphones:

• Omni
• Sub-cardioid
• Cardioid
• Super-cardioid
• Hyper-cardioid
• Figure-8

Multiple combinations of those including:

• Blumlein (two crossed figure-8 microphones in the azimuth plane))
• Height-enabled Blumlein (three orthogonal figure-8 microphones)
  
• M/S (Mid/Side)
  
• XY (two crossed cardioids) separated by any arbitrary angle
  
• Binaural, using HRTF information
  
• Three hypercardioids facing forward and two cardioids facing rearward (for 5.1 surround)
  
• Any combination and arrangement of microphones for surround sound or other effects
