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 par-
       ticular 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.

OPTIONS
       The default options are --fuma, --amb.

       --help Display this text.

       --stin Stereo input files.

       --hpf <frequency>
	      Highpass filter.

       --fuma, --sn3d, --n3d
	      B format standard.

       --invx, --invy, --invz
	      B format inversion.

       --endf Endfire mode.

       --amb, --caf, --wav
	      Output file type.
