DISPLAY AND METER OPTIONS
Instrumentation Menu > RTA
Choosing the
RTA
menu provides spectral analysis from various patch points within Omnia.7. The horizontal scale
along the bottom of the RTA screen shows frequencies from 20 to 20,000Hz. The vertical scale along the left side
shows the amplitude of the audio in decibels.
The
Category, Patch Point,
and
Audio Channel
sub-menus are used to select the specific source audio. The specific
patch points will change depending upon the category. Categories include
I/O, Undo, Physical Inputs, Parametric
EQ Preview, Sidechains, Multiband,
and
Monitor Out.
When the RTA is selected as the current type of instrumentation, controls for adjusting its display are provided in
the Display Options menu. It may be necessary to scroll down to view these controls.
♦
The
Delay
control works the same here as it does previous and subsequent display sections.
♦
The
RTA Resolution
control lets you choose between a 1/3 and 1/6 octave display.
♦
The
Averages
control can be used to slow down or speed up the RTA’s display response. A lower average
setting (faster meter response) might be more useful for peak monitoring; while a higher average setting
(slower meter response) might be more useful for calibrating speakers. Higher averages are also useful
for adjusting lower frequencies. The recommended setting for speaker calibration is 100. Regardless of
how the Averages control is set, the RTA maintains a history “buffer” of 1,000 frames. Advancing the
control to 1,000 will immediately display the average of the last 1,000 frames.
