High Pass

Socket § on the analysis section is the high pass
filter output
. Unlike the other sockets, this is an audio
output
, which sends out the part of the speech signal
which the high pass filter lets through. This is most
usually added to the vocoder output, to make the
modified carrier signal more speech-like still, by inclu-
ding these high frequency elements of the sound.

$

Instrument In

Socket $ on the synthesis section is where you patch
in the instrument that will provide the carrier signal
(see below).

P

Experiment with different sorts of sound for
the carrier signal, for instance

• sawtooth or square waves from a VCO,

• noise (A-118),

• digital noise (A-117).

H

With an A-129 /5 voiced / un-voiced detector
module, you can switch the carrier signal
depending on whether a speech signal is
present.

%

Low Pass • Band 1 • Band 13 • High Pass

The CV inputs % on the synthesis section are where
the control voltages from the analysis section are
patched in.

&

Vocoder Out

Output & on the synthesis section is the audio output
for the whole vocoder.
