TransientControl is a plug-in that allows you to modify dynamics in ways that aren't possible with traditional compressors. You can directly change the transient ("attack") and sustain of your audio; this allows you to make your tracks more punchy, or smooth them out so they sit in a mix. TransientControl features a UI with 3 views: Basic: Provides access to the Transient, Sustain and Gain controls as well as the input meter. Basic w/Process Meter: As above, with the addition of a meter that allows you to see the activity of the plug-in. Advanced w/Process Meter: This view adds access to the advanced controls of the transient and sustain detectors.
