Additional EQ Types

EQ types

New EQ types have been added.

Band Pass

This familiar filter type cuts the low and high frequencies.
It gives the sound a distinctive radio-like character.

Tilt Shelf

Tilt Shelf

Choose a pivot point, and the filter boosts one side while cutting the other.
This is a relatively unusual EQ type.

EQ slopes

More EQ slope options are available as well.

Auto Gain

  • Left red box: Gain and Q are linked to prevent extreme volume changes.
  • Right red box: The level is adjusted automatically when an EQ point is boosted or cut.
