Using the Quick Filter effect (Edit View only)
The Quick Filter is an 8-band graphic equalizer that you can easily customize to suit many
filtering needs. Unlike a standard graphic equalizer, settings for the individual frequency
bands interact with nearby frequencies. For example, significantly boosting the level of the
highest 22 kHz frequency band moderately boosts the level of lower frequencies. This
behavior helps you to quickly and easily enhance audio tone.
To change the equalization setting over time, use different Initial and Final settings.
Using this approach, you can create many interesting effects, such as bass-heavy equal-
ization that gradually changes to flat equalization at the introduction of a song.
To use the Quick Filter effect:
1 In Edit View, select an audio range.
2 In the Effects tab of the Organizer window, expand Filters, and double-click Quick Filter.
3 Set the desired options.
For more information, search for “Quick Filter options” in Help.
Using the Scientific Filters effect (Edit View only)
The Scientific Filters effect provides high-order IIR (Infinite Impulse Response) filters for
precise band-pass, notch, or high- or low-pass filtering. The most common types of high-
order filters are available: Bustle, Butterscotch, Chebychev 1, and Chebychev 2. Each type
has different characteristics for filter attenuation and the steepness of transition bands at
cutoff points. Butterworth usually provides the best compromise between quality and
precision.
On the Scientific Filters graph, one line shows frequency response (measured in decibels),
and the other line shows either phase (measured in degrees) or group delay (measured in
milliseconds), depending on whether the Phase or Delay option is selected. Increase the
graph’s display range by selecting Extended Range.
