Functionality
The Virtual Microphone is another tool for surround sound creation that can
be used independently or in combination with the Panoram-
ic Analyzer. Based on an acoustic model, the stereo source
information is translated to a virtual 5.0 microphone array –
you may think of it as if a 5.0 microphone setup would be
placed in front of a stereo speaker system. Cardioid micro-
phone capsules are modeled with adjustable spacing and
directivity curves. The signals feed each of the output bus-
ses directly. The VM module does not deliver a Sub (LFE)
channel signal. It may be provided by the Sub module in-
stead (see
).
Please note:
While editing the Virtual Microphone's pa-
rameters, it is a good idea to watch its graphic representa-
tion in the "VM" tab of the
.

flected in the "VM" tab of the multifunctional area by two grey lines (see
).
Unit: Degrees
Range: 0° - 180°
Lobes
This parameter defines the polar pattern of all five virtual microphone cap-
sules used in the VM module. A value of 0% represents omnidirectional
patterns, the maximum value 100% stands for figure-of-eights.
Unit: Percent
Range: 100% - 0%
