Delay Sets the delay time between the original
signal and the delayed signal. The higher the
setting, the longer the delay. This control is ad-
justable from 0–1500 milliseconds (1.5 sec-
onds).
Low-Pass Filter Controls the cutoff frequency of
the Low-Pass Filter. Use this to attenuate the
high frequency content of the feedback signal.
The lower the setting, the more high frequen-
cies are removed from the feedback signal.
The range of the Low-Pass Filter is 20 Hz to
19.86 kHz, with a maximum value of Off (which
effectively means bypass).
Feedback Controls the amount of feedback ap-
plied from the output of the delay into its input.
It also controls the number of repetitions of the
delayed signal.
Cross-Feedback Cross-Feedback feeds the de-
layed signals to their opposite channel: The left
channel delay is fed to the right channel input
and vice-versa. The result is a stereo echo that
ping-pongs back and forth between the right
and left channels.
Selecting Audio for Delay Processing
Because Ping-Pong Delay adds additional mate-
rial (a delay tap) to the end of selected audio,
make a selection that is longer than the original
source material to allow the delay tap to be writ-
ten into the end of the audio file.
Selecting only the original material, without
leaving additional space at the end, will cause
delay taps that occur after the end of the region
to be cut off.
Invert
The Invert plug-in reverses the polarity of se-
lected audio. Positive sample amplitude values
are made negative, and all negative amplitudes
are made positive.
This process is useful for altering the phase or
polarity relationship of tracks. The Invert plug-in
is useful during mixing for modifying frequency
response between source tracks recorded with
multiple microphones. You can also use it to
correct audio recorded out of phase with an in-
correctly wired cable.
