1. Pitch Shift Controls
The mode control at the top left of Discord’s window chooses one of three modes of operation for Discord’s
pitch shifters. These modes are:
P1, Vintage: this mode is a careful reproduction of hardware pitch shifters from yesteryear. P1 is also
the pitch shifting algorithm used in previous versions of Discord.
P2, Clean: this mode is similar to P1 but usually produces a cleaner shifted sound than P1,
particularly at smaller shifting intervals. At larger intervals it can take on an interesting metallic
quality that is useful for special effects.
Gr, Granular: this mode is derived from a signal-processing technique called granular synthesis.
Granular synthesis involves chopping a sound into short segments, called grains, and playing them
back at different rates to vary the perceived pitch of the sound. Discord 3’s granular processors are
tailored for pitch-shifting applications but can create unusual effects ranging from a subtle tremolo to
a pointillist spattering of sound.
