5.10.10 Vocoder
A high quality 34 band Vocoder. It uses the audio input of REAKTOR or REAKTOR PLAY
ER as 'modulator': It analysis the amplitude of 35 frequency bands of the incoming signal
and imprints these amplitudes on the oscillator mix. The oscillator mix is the 'carrier' of
the vocoder. It's not possible to use an audio signal as 'carrier'. Please read also the para
graph 'How to get RAZORS Vocoder to work' at the end of this manual.
Use the COLOR Control of the oscillator to increase the speech intelligibility when using a
voice as modulator or to equalize the vocoder sound.
Use the Filter Smoother at the left hand side of the filter to alter the vocoding effect.

▪
FORMANT: Amount of formant shift (semitones) of the filter. Can be used to get a 'mickey
mouse' effect if a voice is used as modulator.
▪
STRETCH
: Stretches the filter curve of the vocoder along the frequency axis.
5.10.11 Formant
Offers several filter presets. The 'Formant Waves' oscillator type shares the same presets.
Some of them have lots of narrow spectral notches. In this case formant shifting can result
in fast amplitude jumps for gritty sounds.
To smooth these fast amplitude jumps use the ATT, DEC, DAMP controls of the 'Filter
Smoother' on the left hand side of the filter.
To learn the functionality of the CENTER parameter modulate the STRETCH parameter with
an LFO and turn the CENTER knob and see how the filter curve on the spectral display (set to
filter 1) is changing.
