40-Band Vocoder
A vocoder uses two sets of band-pass filters (filter banks) to impart the
characteristics of one sound source onto another. The analysis filter
bank determines the level of the input at several different frequencies.
These levels are used to modulate the output levels of the corresponding
frequencies of the synthesis filter bank. The most common use of this
is to send a synthesizer signal into the synthesis input and a voice
(recorded or live via a microphone) into the analysis input to get a
"talking synthesizer" effect.
A . Analysis Sensitivity
This adjusts the gain of the input to the analysis filter bank.
Range:
-100% - +100%
B . Sibilance Boost
This adjusts the level of a high-pass shelving filter at the input to the
analysis filter bank. This will increase or decrease the sibilant
frequencies (consonant sounds) to improve intelligibility or change
the tonality of the vocoder.
Range:
-100% - +100%
C . Decay
This adjusts how quickly the synthesis filters will react to the input
signal. A faster response (lower setting) will usually be more
intelligible, but slower decay times (higher setting) can be more
musical.
Range:
0 - 100%
D . Band Shift
This shifts the frequencies of the Synthesis filter bank, relative to the
analysis filters. The result is a pseudo pitch-shift effect.
Range:
-100% - +100%
E . Synthesis Signal
This selects which signal is sent to the synthesis filter bank.
Range:
Effects Send, Aux Bus, Ext In Left, Ext In Stereo
F . Analysis Signal
This selects which signal is sent to the analysis filter bank.
Range:
Effects Send, Aux Bus, Ext In Right, Ext In Stereo
G . Analysis Mix
This adjusts how much of the analysis signal is mixed into the
output.
Range:
0 - 100%
