BV512 VOCODER572
Introduction
The BV512 is an advanced vocoder device with a variable number of filter bands. It also has a unique 1024-point
FFT vocoding mode (equivalent of 512-band vocoding) for very precise and high quality vocoded speech. By con-
necting the BV512 to two instrument devices, you can produce anything from vocoded speech, singing or drums to
weird special effects.
Even if you have worked with a vocoder before, please read the following section. Knowing the basic terms and pro-
cesses will make it much easier to get started with the BV512!
! Please, note that this device is not available in Reason Intro Rack Plugin.
How does a vocoder work?
Carrier and modulator
A vocoder accepts two different input signals, a “carrier” and a “modulator”. It analyzes the modulator signal, applies
its frequency characteristics to the carrier signal and outputs the resulting “modulated” carrier signal.
In the most typical case, the carrier signal is a string or pad sound and the modulator signal is speech or vocals - the
result will be a talking or singing synth sound. The modulator could also be drums or percussion (for rhythmically
modulated sounds and effects) or any sound with changing frequency content.
Filter bands
Technically, a vocoder works in the following way: The modulator signal is divided into a number of frequency bands
by means of bandpass filters (called the “modulator filters” or “analyzing filters”). The signal in each of these bands is
sent to a separate envelope follower (which continuously analyzes the level of the signal). The carrier signal is sent
through the same number of bandpass filters (the “carrier filters”), with the same frequency ranges as the filters for
the modulator signal. The gain of each bandpass filter is controlled by the level from the corresponding envelope fol-
lower, and the filtered signals are combined and sent to the vocoder’s output.
In this way, the carrier is filtered to have roughly the same frequency characteristics as the modulator. If the modula-
tor signal has a lot of energy in one of the frequency bands, the gain of the corresponding filter band for the carrier
signal will be high as well, emphasizing those frequencies in the output signal. If there is no signal at all within a fre-
quency band in the modulator signal, the corresponding band in the output signal will be silent (as the gain will be
zero for that filter).
There are several factors determining the quality of the vocoder sound, but the most important is the number of filter
bands. The larger the number of filter bands, the closer will the output signal follow the modulator’s frequency char-
acteristics. The BV512 offers 4, 8, 16 or 32-band vocoding.
q Even if a high number of bands will make the sound more precise and intelligible, this isn’t always what’s de-
sired! Vocoding with a lower number of bands can give results that sound different, fit better in a musical con-
text, etc.
FFT vocoding
The BV512 has an additional FFT mode, in which the vocoding process isn’t based on bandpass filters as described
above. Instead, FFT (Fast Fourier Transform) analysis and processing is used. This equals 512 “conventional” fre-
quency bands and results in a very precise and detailed vocoder sound. Note:
