Algorithm List
Vocoder
The vocoder creates "talking instrument" effects. To use Vocoder, input an instrumental sound into the left
channel and a vocal sound into the right channel. The instrumental sound is split into ten frequency bands to be
processed according to its frequency components.
Input R (MIc)
Output L
Output R

Instrumental sounds are input into the L-channel side of the effect. Therefore, it is required to insert and connect
"Lch" of the effect to the channel handling instrumental sounds. Similarly, vocal sounds are input into the R-
channel side of the effect. Insert and connect "Rch" of the effect to the channel handling vocal sounds.
Tips for using Vocoder
It is a good idea to choose instrumental sounds containing a lot of overtones. Recommended .sounds include those
with saw-tooth waveforms such as strings and distorted guitar sounds.
