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.
