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 Gain
Also sometimes referred to as “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: 0% - 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 Input
This selects which signal is sent to the synthesis
filter bank.
