NAME

       tetrafile - Tetrahedral Microphone Processor

SYNOPSIS

       tetrafile <options> <config file> <input file(s)> <output file>

TetraProc

       is  a  microphone  processor, which converts the A-format signals from a tetrahedral Ambisonic microphone
       into B-format signals ready for recording.  TetraProc consists of two parts: the A/B  converter  and  the
       metering and monitoring.  Tetrafile only has the A/B conversion part which is otherwise identical.

       When using tetrafile, make sure to include the high pass filter option with a reasonable cutoff frequency
       - without it some mics (in particular Core Sound's) are very sensitive to LF noise.

       The  default  output  file  type  for  Tetrafile  is  '.amb',  which  is a WAVEX file with a special GUID
       identifying it as Ambisonic.  Not all tools can read this, use either .caf or .wav in those  cases.  Note
       that the file type is set using the command line options and does not depend on the filename extension.
