TetraProc converts the A-format signals from a tetrahedral Ambisonic microphone into B-format signals ready for recording. Main features:

  • A-B conversion using a classic scalar matrix and minimum phase filters, or
  • A-B conversion using a 4 by 4 convolution matrix using measured or computed impulse responses, or a combination of both.
  • Individual microphone calibration facilities.
  • 24 dB/oct higpass filters.
  • Metering, monitoring and test facilities.
  • Virtual stereo mic for stereo monitoring or recording.
  • Unlimited number of stored configurations.
  • Jack client with graphical user interface.

TetraCal is the microphone calibration application for TetraProc. Given a number of impulse response measurements of a tetrahedral microphone (captured using Aliki) it computes the matching configuration file for TetraProc. Main features:

  • Automatic determination of gain and directivity errors of the A-format microphones.
  • Automatic computation of an A-B matrix compensating for those errors.
  • Frequency and phase response display of all A and B format signals.
  • Interactive adjustment of pre- and post matrix equalisers.
