3.4.3.6 Microphone Simulation Tool (MST) – User Pan Mode
As a further sophistication of the VSP system, a Microphone Simulation Tool
(MST) has been created. This allows the mix engineer to create his/her own
multi-channel panning law, by simulating the placement of microphones in
a virtual space.
Overview
A user can define how the VSP varies the delays and amplitudes of the direct
sound when panning between speakers. To instruct the VSP how to generate
these signals, commonly known microphone symbols are used. Each symbol
represents the signal that will be sent to one speaker.
For example, if five omni microphones are set up at the same position, no pan-
ning effect will be achieved. Five omni microphones at certain distances will
only create time differences when panning between speakers. Five shotgun
microphones positioned in one location will only generate amplitude diffe-
rences. And five directional microphones positioned in different locations will
generate both amplitude and time differences between the speakers (based on
the placement of the ‘microphones’).

Simulated Microphone Placement
Virtual Room
The dry signal within a VSP channel is now placed to an imaginary position
based on the panner positioning within the channel. You can now imagine
that, if each speaker (in your monitoring environment) is fed the signal based
on the placement of the ‘microphones’ in the simulation (including the reflec-
tions), that a realistic sound space could be achieved. This is a simplification
of what happens within the VSP system.
Each of the Panner modes (ORTF, AMP, AB, etc.) simulates a different place-
ment of the microphones, and therefore yields a different acoustic scene.
