Region Gain and Automation
Region Gain envelopes are often used for repair work, such as reducing unwanted breaths, accentuating syllables, or reducing noise. The “region gain envelope” is part of the audio region, and is applied before any other processing is applied in the mixer strip. Region Gain only adjusts the volume (level) of the region across time.

Processor Automation is often used for creative changes such as fading elements in and out during a song. Automation can be applied to many different mixing parameters including the input trim, fader, panning, muting, or plug-in parameters.
