CHAPTER 5
Meyer Sound offers two comprehensive tools to assist you
with the acoustical and functional requirements of system
design and optimization. This chapter introduces you to the
Meyer Sound MAPP Online acoustical prediction program,
and the SIM audio analyzer, a robust instrumentation
package for system measurement, analysis, and more.
MEYER SOUND MAPP ONLINE
The MAPP Online prediction program is a powerful, cross-
platform, Java-based application for accurately predicting
the coverage pattern, frequency response, impulse
response, and maximum SPL output of single or arrayed
Meyer Sound loudspeakers.
Figure 5.1. MAPP Online is an intuitive, powerful system design tool
Residing on your computer, the MAPP Online prediction
program facilitates conguring arrays of a wide variety
of Meyer Sound products and, optionally, denes the
environment in which they will operate, including air
temperature, pressure, and humidity, as well as the location
and composition of walls. You can nd the program at:

NOTE: In order to use the MAPP Online
prediction program, you will need to register
by clicking “Apply for MAPP Online” on the website
listed above. After registration and upon approval,
an e-mail will be sent to you with a user name and
password along with the address for the website
where you can download MAPP Online.
As its name indicates, the MAPP Online predition program
is an online application: When a prediction is requested,
data is sent over the Internet to a high-powered server at
Meyer Sound that runs a sophisticated acoustical prediction
algorithm using high-resolution, complex (magnitude and
phase) polar data. Predicted responses are returned over
the Internet and displayed on your computer in color.
With the MAPP Online prediction program, you can:
Plan an entire portable or xed loudspeaker system and
determine delay settings for ll loudspeakers.
Clearly see interactions among loudspeakers and
minimize destructive interference.
Place microphones anywhere in
the sound eld and predict the
frequency response, impulse
response, and sound pressure
level at the microphone position
using MAPP Online’s Virtual SIM
feature.
Rene your system design to
provide the best coverage of the
intended audience area.
Use a Virtual VX-1 program
equalizer to predetermine the
correct control settings for best
system response.
Gain valuable load information
about the array to determine
rigging capacities.
The MAPP Online prediction program
enables you to come to an installation
with a wealth of information that
ensures the system will satisfy your requirements “out of
the box” – including basic system delay and equalization
settings. Its accurate, high-resolution predictions eliminate
unexpected onsite adjustments and coverage problems.
MAPP Online is compatible with Windows, Linux®, Unix®,
and Apple® Macintosh® computers running Mac OS® X
version 10.1.2 or higher. The MAPP Online Web page lists
additional system requirements and recommendations.
