DESCRIPTION

TetraMic allows the recording of an accurate sound field, recording four channels of audio in “A” format, which are then transformed using software into “B” format (W, X, Y and Z). Format B can then be interpreted via the four channels to essentially any single-point configuration of microphones. The apparent orientation of the sound field can be rotated, tilted, tumbled or zoomed post-recording.

The four channels of “B” format can also be interpreted into almost any playback format, including:

  • mono (without “sum to mono” phase cancellation issues)
  • stereo
  • binaural, using HRTF information
  • four speakers arranged as a square or rectangle
  • six speakers arranged as a regular or irregular hexagon
  • 5.1 (ITU)
  • 7.1
