Increasing Density/Loudness - Omnia ONE Installation And Operation Manual

The Omnia.ONE AM is definitely capable of generating moment-to-moment loudness; it has the muscle. It also
maintains that famous Omnia clarity sought after by top programmers all over the world.
Omnia.ONE AM is designed to minimize the impact of the quality vs. loudness trade-off.
If you believe that you're in a loudness war and you feel a need to react, we can provide some suggestions that
should help. Conversely, if you have the luxury to strive for increased sound quality, we've got suggestions for you
too!
Omnia.ONE AM has been designed to minimize the trade-offs between quality and loudness, and we recommend
that before starting the process of cranking it up, try to determine beforehand what sonic characteristics might be
lacking.
In many cases it's not just about increasing the drive to the limiters. Instead, it can be as non-intuitive as creating the
illusion of greater loudness by changing something simple – like a time constant. Sometimes the old adage of less is
more really applies!
Please give the following content some thought as it may assist you in developing an overall fine-tuning plan if you
feel changes beyond our factory presets are justified.
The trade-off between quality and loudness is primarily determined by how you choose to use the limiting and
clipping sections. While each function alone will generate "dial presence," they each have different advantages, as
well as side effects.
When excessive limiting is used, intermodulation distortion is increased, making the audio sound "mushy", and
"smeared." The added short-term density can also cause the audio to be "tight", "squashed", or "dense." The
dynamics" artifacts caused by excessive limiting might sound like "pumping," "breathing." The rule for limiting is
"a little goes a long way!"
When excessive clipping is used, harmonic distortion is increased. The audio level is in effect "running into the
brick wall." Too much clipping can cause the audio to sound "broken-up," "torn," "rough," or "edgy." As might be
expected, the harder the limiters and clippers are driven, the louder the perceived audio. However, you are also
much more likely to encounter increased intermodulation and/or harmonic distortion.
The following sections are provided to assist you in designing the personality of your sound. As we said earlier,
there is no precise recipe for setting up audio processing because each application is different. However there are a
few basics that we can share with you that can help get you to where you want to go. Setting up processing for the
absolute best end product usually requires a concerted effort, some extended periods of critical listening, and making
a few intelligently chosen and subtle changes over time. It will be time and effort well spent, and all you need to
know up front is that you must:
 Know your goals (have a plan).
 Take your time.
 Always adjust deliberately and methodically.
 Listen critically before making more adjustments.

Increasing Density/Loudness

Try to resist the temptation to crank up the aggressive processing sections. They will definitely add loudness but
usually at the cost of quality and intelligibility. Many times, just building a bit more RMS energy in the AGC
sections will do the trick.
The following are some suggestions on where to begin to make changes. For best results you should try them in the
order we have listed below.
Increasing loudness can be accomplished in five ways:
