Flange & Chorus effect (Pro only)
The Flange & Chorus effect lets you adjust both the flange and chorus. Chorus is commonly used to add depth and
character to audio footage that contains a single instrument or voice. Chorus makes one voice sound like many
voices.
Flange applies a copy of the sound that is detuned, or played at a frequency slightly offset from the original. By exper-
imenting with the voice separation time and the modulation depth, you can create a wavy, rushing sound. The
default settings apply to flange alone.
