CHAPTER 6
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
Meyer Sound MAPP Online — a powerful online acousti-
cal prediction tool — and the SIM audio analyzer, a robust
instrumentation package for system measurement, analysis,
and more.
MEYER SOUND MAPP ONLINE
MAPP Online (Figure 6.1) is a powerful, cross-platform,
Java-based application for accurately predicting the cover-
age pattern, frequency response, impulse response, and
maximum SPL output of single or arrayed Meyer Sound
loudspeakers.
Figure 6.1. MAPP Online is an intuitive, powerful system design tool.
MAPP Online facilitates configuring arrays of a wide variety
of Meyer Sound products and, optionally, defines the
environment in which they will operate, including air tem-
perature, pressure, and humidity, as well as the location and
composition of walls. You can find MAPP Online at:
www.meyersound.com/products/software/mapponline
NOTE: In order to use MAPP Online, you will
need to register by clicking “Apply for MAPP
Online” on the Web site listed above. After registra-
tion and upon approval, an e-mail will be sent to
you with a user name and password along with the
address for the Web site where you can download
MAPP Online. Online instructions will guide you
through the download and setup process.
As its name indicates, MAPP Online is an online applica-
tion: 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 MAPP Online, you can:
■ Plan an entire portable or fixed loudspeaker system and
determine delay settings for fill loudspeakers.
■ Clearly see interactions among loudspeakers and mini-
mize destructive interference.
■ Place microphones anywhere in
the sound field and predict the
frequency response, impulse re-
sponse, and sound pressure level
at the microphone position using
MAPP Online’s Virtual SIM feature.
■ Refine your system design to
provide the best coverage of the
intended audience area.
■ Use a virtual VX-1 program equal-
izer to predetermine the correct
control settings for best system
response.
■ Gain valuable load information
about the array to determine rig-
ging capacities.
MAPP Online enables you to come
to an installation prepared with a
wealth of information that ensures
the system will satisfy your require-
ments “out of the box” – including
basic system delay and equalization settings. Its accurate,
high-resolution predictions eliminate unexpected on site
adjustments and coverage problems. With MAPP Online,
every sound system installation has a maximum chance of
success.
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 above lists
additional system requirements and recommendations.
