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.

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

       --help Display this text.
