Multimeter
This plug-in consists of a collection of professional gauge and analysis tools, namely;
a 1/3 octave Analyzer
a Goniometer for judging the phase coherency in the stereo sound field
a Correlation Meter to spot mono phase compatibility
an integrated Level Meter
The control panel to the left of the display allows you to switch between the Analyzer
and Goniometer, and contains parameter controls for the Multimeter.
The Stereo level and Phase Correlation meter is always displayed.
1/3 Octave Spectrum Analyzer
This tool analyses the level of 31 independent frequency bands. Each frequency band
represents one third of an octave. The Analyzer complies with the specifications
outlined by lEC document 1260.
Analyzer Button
The Analyzer button activates the Analyzer (and deactivates the Goniometer). The four
buttons below determine the portion of the Input signal that the Analyzer displays.
You can choose to view the Left or Right channel independently.
LR max shows the maximum Band levels of either channel, while Mono displays the
levels of the stereo signal as a summed mono entry.
View
The View options determine the level represented by the top line of the scale shown in
the display (Top; range:40 to
+
20 dB) and the overall dynamic range of the Analyzer
(range; range: 20 to 80 dB).
These two parameters can also be set directly in the bar graph. To do so, click-hold and
drag on the bar graph to move the top line of the display. Click-holding and dragging
directly on the dB scale allows you to compress or expand the range of the scale.
