NAME

       tetraproc - Tetrahedral Microphone Processor

DESCRIPTION

       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.

       Both  TetraProc	and  TetraFile	will normally use the Furse-Malham form of B-format in which the W signal is attenuated by 3dB w.r.t.  the
       first order ones. Both can also use the 'normalised' and 'semi- normalised' forms if required. For safety, this can be changed on the  com-
       mand  line  only, and Tetraproc will show the current setting in its metering window. Note that the coefficients shown in the config window
       are independent of this - they are _always_ in the semi-normalised form (i.e. they do not include the 3dB attenuation on W  for	Furse-Mal-
       ham, nor the 4.8dB gain on XYZ for the normalised one).

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.
