SIM 3

The Power of Real-Time Acoustic Analysis

The SIM Story

Meyer Sound’s award-winning Source Independent Measurement (SIM) system is widely recognized as the world's most accurate acoustical audio analysis tool for studios, live performance spaces, and permanent installations. SIM 3 takes advantage of more than three decades of research and development to perform powerful computer-based analysis of a sound system, component, or acoustic space and offer solutions for optimizing audio performance. SIM 3 provides a detailed snapshot of system behavior, decomposing complex audio information to identify acoustic anomalies and determine corrective steps. Unlike other analyzers that require impulse or noise references for the best accuracy, SIM 3 can use music as a source—even music that’s compromised by environmental factors like excessive reverberation or noise.

Inside the System

SIM 3 is an integrated hardware and software system that can analyze program material such as music to calculate the transfer function of a sound system or space, by measuring and comparing input and output signals of each component in the system. Characteristics such as polarity, distortion, dynamic range, and radiation patterns are measured, and components can be precisely aligned using SIM to guide setting of crossover parameters, delay times, equalization, levels, and speaker positions. And since SIM is multichannel, your time can be spent measuring instead of setting up or patching over and over again.

Power, Speed, and Accuracy

Real-time data acquisition is crucial for accurate spectral analysis. SIM 3 processes audio data more accurately than any comparable tool, acquiring data in real time and processing information at 32-bit floating-point resolution. The system performs more than 2,000 FFTs per second, returning results at high resolution in less than one second. Audio is measured from 8 Hz to 22 kHz at 1/48-octave resolution, with amplitude accuracy within 0.1 dB.

Total Versatility

SIM is about so much more than sound system alignment. Use SIM to determine the actual level that causes clipping at a device’s input, output, or even within its internal signal path, regardless of the device’s meter readout. Easily quantify latency in a digital processor or equalizer at different settings, or measure ringing or phase shift in a filter. Measure microphone signatures: By comparing the outputs of a lavalier microphone and a reference microphone, for example, SIM 3 can determine corrections necessary to match the sound of the lavalier to the reference in seconds. Verify the performance of equipment in your rental inventory by comparing the device’s transfer function with a reference measurement made when that device was first put into service.


A Comprehensive System Approach

Sophisticated Software

SIM 3’s software makes accessing and understanding system data easy, featuring intuitive, comparative trace graphs that display multiple transform functions at once. The software offers views of pertinent frequency spectra, impulse response, and frequency response at key points in the system.

The Audio Analyzer

The 3022 Audio Analyzer is the nerve center of the SIM system. This rackmount hardware unit features two line inputs, two microphone inputs with phantom power and instrumentation-grade preamps, 24-bit converters, and a lab-quality, multifunction digital signal generator. Expand with specialized multichannel line and microphone switchers for even more flexibility.

Line and Mic Switchers

For large-scale or sophisticated system analysis, add optional line-level and microphone switchers to monitor multiple points in the chain. Patch in the SIM-3088 16-channel analog line-level switcher and you’ll be able to measure any point in the system without ever touching a patch cable. The SIM-3081 8-input mic-level switcher enables measurements in several zones by using multiple mics. Meyer Sound Galileo GALAXY products integrate as 16-channel line switchers when used with SIM 3; selectable probe points are available for measurement within the GALAXY output stage.

Power and Accessories

A host of accessories let you customize your SIM 3 system for your unique needs. The SIM-3044 Remote Power Supply powers additional line and mic switchers; other accessories include cable bundles, D-Sub extension panel, cases, racks, mic switcher mounting tray, mic switcher boot, and rear rack rail kit.
