Vocoder
The vocoder principle: Carrier material (e.g. a surface sound or a synth chord) is affected by a
modulator (e.g. language or singing) so that one gets the impression that it is speaking or singing.
Rhythmic surface sounds can also be developed if modulated with a drum loop.
This is done via the transmission of the frequency characteristics of the modulator (speech) on the carrier
(chord).
Carrier input
Here you have to select the desired carrier sample. Some special carrier samples that have been loaded
automatically from the "Vocoder" directory are listed.
Use the "Carrier sample" check box to load any number of
samples of the current project or predefined carrier sample.
Here you can play the carrier on its own for test purposes.
Noise:
This controller lets you add noise to the carrier sample. This makes sense if the carrier material can not
be modulated sufficiently or is irregular. It's good for "filling" drum loops which have too many pauses
between the beats.
Material containing all frequencies in equal amounts are particularly suitable, such as strings, orchestra
chords, broad synthesizer pads, hissing, or wind noise.
Filter
Dynam:
Influences the dynamics of the modulator signal to reduce the modulation depth of the vocoder.
This prevents two often undesired side effects of modulation. On the one hand, the volume change of the
modulator signal is added to the output signal in a slightly more moderate form which may improve the
power of the vocoder voice. On the other, the low-level share of the modulator signal is ignored in order
to prevent modulation of the carrier by breathing or noise.
Smooth:
Affects the speed at which the vocoder adjusts to the modulator spectrum. The greater the value, the
"lazier" the vocoder follows the modulator and the "smoother" the sound changes in the carrier sound.
Filter graphic
Any frequency characteristic can be drawn in to optimize the results of the vocoder. For example, simple
disturbing bass frequencies can be eliminated as the curve is corrected downwards to the left. Similarly,
weak highs can be strengthened as the curve is raised to the right.
Mixer
In the mixer you can also mix parts of the carrier and modulator signal to the vocoder output signal
("Out").
If the output signal of a track is used as a carrier in the vocoder, this track will be muted first, and then
you can make it audible again in the vocoder mixer.
