OTHER SIMULATION TOOLS
• AniScape mode returns a direct sound response with the first
order (early) reflections missing (this is because AniScape
provides the first order reflections during a simulation).
• Static mode returns a sound response file which includes the
first order reflections of the simulated room, this means that
the sound object will appear to be “static” in the room (first
order reflections will always appear to come from the same
place).
It is possible to use AniScape mode sound response files with
MultiScape and Space Array. However, MultiScape and Space
Array do not add first order reflections during a simulation.
When producing a room response for a MultiScape or Space
Array simulation AniScape mode is preferred over the static
mode, as static impulse responses will not appear to move
through the Soundscape correctly (ie. the first order reflections
do not change locations while later reflections do).
When AniScape mode is selected the Make Room application
will produce a room geometry file (*.GEO). The *.GEO file is
a text file containing information on the room’s attributes used
to calculate first order responses during an AniScape
simulation.

There are three types of microphone simulated in the Make
Room application. Each microphone type mimics the
properties and produces signal files which mirror the signals
generated by their real life counterparts.
Most microphones (with the exception of B-format
microphones), have characteristic sensitivity lobes. These lobes
correspond to the sensitivity of the microphones in certain
directions. In the Make Room application this effect is
simulated by including a directivity factor for the microphone in
calculations.
The Directivity Factor which describes the characteristic sound
lobes of a Microphone are described in the table below.
The three types of microphone simulated in Make Room are
Mono, Stereo and B-format. Each type, their properties and
resultant responses are described below:
Mono Microphone: This setting allows the simulation of a
simple monophonic microphone. The microphone is
