bandwidth, you increase the overlap of the lter bands. A bandwidth of 100% is the most
accurate, but higher or lower settings can create interesting effects.
The Precise/Retro switch toggles between two types of lter behavior. In Precise mode,
all lters have the same gain and bandwidth. In Retro mode, bands become narrower and
louder at higher frequencies.
Gate sets a threshold for the lterbank. Any bands whose levels are below the threshold
will be silent.
The Level slider boosts or cuts Vocoder's output.
Depth sets how much of the modulator's amplitude envelope is applied to the carrier's
signal. At 0%, the modulator's envelope is discarded. At 200%, only high amplitude peaks
will be used. 100% results in classic vocoding.
The Attack and Release controls set how quickly Vocoder responds to amplitude changes
in the modulator signal. Very fast times preserve the transients of the modulator, but can
cause distortion artifacts.
The Mono/Stereo switches determine how many channels are used for the carrier and
modulator. In Mono mode, both the carrier and modulator are treated as mono sources.
Stereo uses a mono modulator but processes the carrier in stereo. L/R processes both the
carrier and modulator signals in stereo.
The frequencies of the carrier's lterbank can be shifted up or down via the Formant knob.
With voice as the modulator, small Formant changes can alter the apparent gender of the
source.
The Dry/Wet control adjusts the balance between the processed and dry signals.

Vocoder Tips
This section explains how to set up the most common Vocoder applications.
Singing Synthesizer
The classic vocoder application is the singing synthesizer. To set this up in Live:
