On the road, reliability always triumphs over perceived
convenience. While it may seem the easiest approach to install
a software-only tool on a laptop computer, the well-known reality
is that general-purpose systems such as personal computers are
a Pandora’s box of problems with compatibility, stability,
operating system and security updates, and the computational demands
of serious acoustical audio analysis.
The embedded operating system in the SIM-3022 audio
analzyer is much smaller than commercial operating systems, meaning
and a lean, mean system without extraneous software to steal processor
cycles or cause instability. The SIM 3 analzyer’s dedicated
processor hardware is built to exacting Meyer Sound standards for
software stability, using ruggedized industrial format PC boards
to ensure survival day after day in the field.
The roadworthy rack mount package is compact and
highly portable and the only moving parts in the entire unit are
onboard CD-RW drive; the operating system and application are stored
in a 1 GB Fast Flash Disk, which is faster and more robust than
conventional hard disks, so that important software components
are secure and protected at all times.
The software is bulletproof and 100% compatible with
other units: In the event that your SIM 3 rig should become damaged
or lost in transit, all that is needed for recovery is to obtain
another unit and load data saved onto CD-RW. Since each processor
unit is identical, there are no software configuration or hardware
compatibility issues to address and the user interface and connections
will always be the same.
The SIM 3 audio analyzer system is more
than a sound system alignment tool – it can be used to
typify the effects of any system. For example, by comparing
of a lavalier microphone and a reference microphone, SIM 3
can show the correction necessary to match the sound of the
lavalier to the reference in seconds. The extreme precision
and wide-ranging analytical capabilities of the SIM 3 analzyer
can be applied to an electronic device to see its actual performance
such as latency, distortion products, impulse response, phase,
stereo operation (left/right channel comparisons), noise, simple
gain, and clip points.
SIM 3 can verify the performance of a piece of equipment
in rental inventory by comparing the device’s transfer
function with a reference measurement made on the same device
when it was first put into service, or determine the actual
signal level that causes clipping at a device’s input,
output or even within its internal signal path, regardless
of what the device’s metering or user interface might
say. Latency in a digital processor or equalizer at different
settings can be quantified easily, as can ringing or phase
shift in a filter.
