PROGRAM:
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.
