Duet
is a double-tracking/harmonizer effect developed to enhance
vocals or instruments, such as guitars, by thickening the sound and
adding a rich glossy sheen to the audio material.
Duet works
by independently pitch-shifting the left and right inputs using a novel
synchronous overlap and add technique, allowing pitch to be manipulated
in real-time, while still maintaining the time duration of the audio.
By
also delaying the re-pitched audio and altering its pan position, Duet
can accurately create the illusion of multiple voices and add a
luscious texture to your music.
Traditional modulation
effects such as flangers and phasers modulate time duration as well as
pitch so can sound synthetic but by de-coupling pitch from time, Duet
creates natural sounding results and can turn a single voice into a
choir.
