The VOCODER ANALYSIS and VOCODER SYNTHESIS modules form a basic modular vocoder.
The vocoder needs two input signals: a voice element which serves as the raw material for the tonal shaping, and is patched into the analysis section (VOCODER ANALYSIS module);
and a carrier signal, which is patched via the instrument input into the synthesis section (VOCODER SYNTHESIS module).
The speech signal is chopped up and analyzed in the VOCODER ANALYSIS module, and then combined with the carrier signal in the VOCODER SYNTHESIS module synthesis section.
As a result of this procedure, the carrier signal assumes the tonal character of the speech signal, but with its own pitch maintained.
There’s also the possibility of connecting the frequency bands of the analysis and synthesis sections arbitrarily, so that, for instance,
a low frequency band in the speech signal can control a high frequency band in the carrier signal.
Env. Pol. control knob allows you to change incoming signals polarity for the internal VCAs.
Out Level control knob acts as attenuator when CV In inserted.
