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 command 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-Malham, nor the 4.8dB gain on XYZ for the normalised one).
