DISPLAY AND METER OPTIONS
Loudness Matched A/B Menu
The ability to compare the sound of the input audio to the processed output audio is valuable when adjusting your
processing. Because the human ear often misinterprets “louder” as “better” for the first few seconds after it hears a
new sound, making sure the average levels of the input and output audio closely match eliminates that distraction
so that your ear can concentrate on the other changes the processor is making to the texture, dynamics, and spectral
balance of the audio.
It is possible to manually adjust these levels in the Monitor Output Menu as you switch back and forth between
patch points, but because input levels vary so much within and between songs, this can get tricky (or just plain
annoying), throws your ear for a momentary loop, and takes your mind off the careful study of the changes you’re
making to your processing.
To make A/B comparisons easier, Omnia.7 can apply automatic leveling to several key input patch points and
makes those available here in the Meter Options Menu (for display purposes) as well as in each of the Monitor
Outputs menus.
Note:
This leveling function affects ONLY the audio available at the patch point. It has NO effect on the
on-air processing.
♦
The
Integration Time
setting controls the integration time of the two ITU BS.1770 loudness meters that
form the basis for the loudness comparison. The loudness is equalized by a ramping gain to account for
the difference between the two loudness meters. The default time is 1 second; 3 seconds is optional. The
1 second integration time will cause the leveler to respond to differences in level more quickly, providing
more consistent levels between A and B, while the 3 second time will allow more level variation and
reduces the likelihood of audible pumping.
♦
The
Source
control allows you to choose the audio source for the Loudness Matching patch point.
Available options are Program Input and Post Multiband.
♦
The
Match
control allows you to choose which audio source will be loudness matched.
