Attack Time Screen
Clicking on the Attack tab opens up the attack adjustment screen.
The attack time of a limiter is a measure of how fast it responds to an audio peak
when­an­audio­peak­exceeds­the­limiter­threshold.­Shorter­attack­times­cause­the­
limiter to respond to audio peaks quicker, affording more accurate peak control, but
­excessively­short­attack­times,­while­creating­“perfect”­peak­control,­can­literally­suck­
the life out of musical material.
At­the­other­extreme,­excessively­long­attack­times­can­allow­audio­peaks­to­escape­
the­limiters­largely­unmanaged,­leaving­them­to­be­controlled­solely­by­the­final­look­
ahead output limiter.
The­ attack­ times­ for­ each­ band­ are­ adjustable­ from­ 0.1­ milliseconds­
(100­microseconds)­to­100­milliseconds.­As­explained­above,­faster­attack­times­exert­
more control over audio peaks, while slower attack times allow peaks to escape the
limiter section with less control.
Attack­times­are­generally­adjusted­to­taste,­keeping­in­mind­that­the­slower­the­
attack­time­the­more­work­the­limiter­must­do,­while­conversely­the­faster­the­attack­
time­the­fewer­short­term­dynamics­the­program­material­will­have.
Generally,­lower­frequencies­require­slower­attack­times­and­higher­frequencies­
require faster attack times for a given amount of control.
The­attack­times­of­each­band­may­be­individually­or­collectively­modified­using­
the­GUI­operating­instructions­provided­earlier.

settings - what sounds right and works right in the specific application is right!”
