produces a chorus effect, lower the Overlapping percentage. Doing so, however, can produce a choppy sound. Simply
adjust Overlapping to strike a balance between choppiness and chorusing. Overlapping can be as high as 400%, but
you should use this value only for very high speed increases (200% or more).

Multitrack effects
Envelope Follower effect (Multitrack View only)
The Multitrack > 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.

Apply the Envelope Follower effect
1
In separate tracks, position two audio clips so that the sections you want to process together overlap.
2 Select the Hybrid tool or the Time Selection tool .
3 In the Main panel, select the range you want to process.
4 Ctrl-click both audio clips.
Note: If you select a range by dragging across a clip, that clip is selected by default; if you Ctrl-click the clip, you will
deselect it.
5 Choose Effects > Envelope Follower, and set the desired options.
Envelope Follower options
Analysis Wave Specifies which waveform to use as the analysis wave. In other words, it provides the amplitude
envelope. You can choose any waveform in the session window.
Process Wave Specifies which waveform to apply the analysis waveform to. You can choose any waveform in the
session window.
Output To Specifies which track to output the resulting waveform to. The default setting is the next available track.
