Using the Envelope Follower effect (Multitrack View only)
The Envelope Follower effect varies the output level of one waveform based on the input
level of another. The amplitude map, or envelope, of one waveform (the analysis wave) is
applied to the material of a second waveform (the process wave), resulting in the second
waveform taking on the amplitude characteristics of the first. This effect lets you, for
example, have a bass guitar line that sounds only when a drum is hit. In this example, the
drum waveform is the Analysis wave, and the bass guitar waveform is the Process wave.
In addition to applying an amplitude envelope to a waveform, you can alter the dynamic
properties of the resulting signal with a variety of settings to otherwise expand, gate,
compress, or limit it.
To use the Envelope Follower effect:
1 In Multitrack View, position the wave clips so that the sections you want to process
together are aligned.
2 Select the Hybrid tool or the Time Selection tool .
3 In the track display, select the range you want to process.
4 Ctrl-click the wave clips you want to process.
Note: If you select a range by dragging across a clip, that clip is selected by default; if you Ctrl-
click the clip, you deselect it.
5 In the Effects tab of the Organizer window, expand Multitrack, and double-click
Envelope Follower.
6 Set the desired options.
For more information, search for “Envelope Follower options” in Help.
Using the Frequency Band Splitter effect (Multitrack View only)
The Frequency Band Splitter lets you take a selected waveform clip (or a highlighted
section thereof) and make up to eight copies of it, with each copy assuming a different
frequency range of the original. Split points are determined by the crossover frequencies
you specify. Each copy of the waveform is placed in its own track in the session window.
You can then edit or apply effects to each band separately.
