.SH NAME
tetrafile \- Tetrahedral Microphone Processor
.SH SYNOPSIS
.B tetrafile
\fI<options> <config file> <input file(s)> <output file>\fR
.SH TetraProc
is a microphone processor, which converts the A-format signals from
a tetrahedral Ambisonic microphone into B-format signals ready for
recording.
.B TetraProc
consists of two parts: the A/B converter and the
metering and monitoring.
.B Tetrafile
only has the A/B conversion
part which is otherwise identical.
.PP
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.
.PP
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.
