System Design and Integration Tools
MAPP System Design Tool
MAPP is a powerful, cross-platform application for accurately predicting the coverage pattern, frequency response, phase response, impulse response, and SPL capability of single or arrayed Meyer Sound loudspeakers.
MAPP System Design Tool
Whether planning for fixed installations or for tours with multiple venues, you can use MAPP to accurately predict the appropriate loudspeaker deployment for each job, complete with coverage data, system delay and equalization settings, rigging information, and detailed design illustrations. MAPP’s accurate, high-resolution predictions ensure that systems will perform as expected, thereby eliminating unexpected coverage problems and minimizing onsite adjustments.
The key to the accuracy of MAPP’s predictions is Meyer Sound’s exhaustive database of loudspeaker measurements. Performance predictions for each loudspeaker are based on 720 1/48th-octave-band measurements taken with a SIM audio analyzer in the Meyer Sound anechoic chamber. The extraordinary consistency between Meyer Sound loudspeakers guarantees that predictions from MAPP will closely match their actual performance.
MAPP client software lets you configure Meyer Sound loudspeaker systems and define the environment in which they operate, including air temperature, pressure, humidity, and even the location and composition of surfaces. You can also import CAD (.DXF) files containing detailed venue information to act as a visual aid.
MAPP prediction requests are sent by the client software to Meyer Sound servers, where complex, high-resolution (magnitude and phase) polar data is processed with sophisticated acoustical prediction algorithms. The resulting predictions are then displayed in the MAPP client software.
With MAPP, you can:
Simulate different loudspeaker configurations to refine system design and determine the best coverage for intended audience areas
Monitor loudspeaker interactions to locate constructive and destructive interferences so that loudspeakers can be re-aimed and repositioned as necessary
Place microphones anywhere in the sound field and predict loudspeaker frequency response, phase response, and sound pressure levels as measured at each microphone position
Determine delay settings for fill loudspeakers using the Inverse Fast Fourier Transform feature
Preview the results of Galileo or Galileo Callisto processing to determine optimum settings for the best system response
Automatically calculate load information for arrays to determine rigging capacity, front-to-back weight distribution, and center of gravity location
Generate and export system images and full-system PDF reports for client presentations

Sim Measurement System
The SIM audio analyzer is a high-resolution audio measurement system comprising software, hardware, microphones, and accessory cables. SIM presents measured audio frequencies at a resolution of 48 points per octave, where the 48 points per octave are arranged in even frequency increments in each octave group, equal to the total frequencies in that octave divided by 48. This resolution allows application of precise corrections to balance system response using frequency and phase domain information.
Source Independent Measurement Technique
The SIM 3 audio analyzer implements Meyer Sound's source independent measurement technique, a dual-channel method that accommodates statistically unpredictable excitation signals. Any excitation signal within a desired frequency range can be used to obtain highly accurate measurements for acoustical or electronic systems.
For example, during a performance, both the input signal and the measured output of the loudspeaker system can be captured and used as a SIM test signal, so you can:
View measurement data as amplitude versus time (impulse response) or amplitude and phase versus frequency (frequency response)
Utilize a single-channel spectrum mode
View frequency domain data with a logarithmic frequency axis
Determine and internally compensate for propagation delays using the SIM 3 Delay Finder
SIM Applications
SIM's main applications are testing and aligning loudspeaker systems, which entails:
Measuring propagation delays between subsystems to determine appropriate polarities and delay time
Verifying correct polarity
Measuring variations in frequency response caused by the acoustical environment and the placement and interaction of the loudspeakers to determine corrective equalization
Optimizing subwoofer integration
Optimizing loudspeaker arrays
The SIM audio analyzer can also be used in the following applications:
Microphone calibration and equalization
Transducer evaluation and correction
Echo detection and analysis
Vibration analysis
