Linear Acoustic Mobilizer Settings

Linear Acoustic CrowdControl technology isolates and protects important dialogue infor-
mation and pre-corrects for downstream phase and equalization "enhancements" offered
by default on many television sets. Used by the leading sports broadcast networks and local
stations, CrowdControl enables broadcasters to protect their valuable assets against so-
called "hyper-surround" systems that provide interesting albeit uncontrolled effects with
some content but dialogue intelligibility problems with other content.
Mobile DTV standards are very new, but research into the devices that would eventually
reproduce the audio and video content was well underway. So too was a modern under-
standing of how human auditory perception performs in noisy environments. Just like
chocolate and peanut butter, or spaghetti and meatballs, the two were naturally destined to
compliment each other.
The work done to create CrowdControl auspiciously provides a stable foundation for what
is necessary with mobile audio. While aggressive traditional processing does allow more au-
dio fit into a smaller box, it is all the wrong audio. Think about the common situation of
having a conversation in a noisy environment- the last thing you want to do is to turn down
the loudest parts and turn up the softest parts of everything. Then you end up with fore-
ground and background noise at the same level and the intelligibility of your conversation
decreases. This is exactly what traditional wideband, single band or multiband audio pro-
cessors do. In fact, it is also what the processing section of other Linear Acoustic AERO
processors do.
What is necessary then is the ability to only affect the important foreground material and
do so in a way that enhances intelligibility. Mobilizer does just this. Controls are named in
a way that makes simples sense, and many will have an immediate audible result, however
some are controlling aspects of the processing that may only become active under certain
conditions.
These controls will be described below. They are applied prior to the processing presets,
but work in tandem with the factory settings.
MB Type
Described in detail in Chapter 2, this simply selects the signal routing for the two possible
Mobilizer processing engines.
Clarity Enhance
As in CrowdControl, Clarity Enhance adjust the level of the audio that is coherent in level
and phase between the two input channels. Increasing this essentially boosts level of dia-
logue. Default Setting: 3.00 dB
