Chapter 72: AIR Stereo Width
AIR Stereo Width is an RTAS plug-in that you
can use to create a wider stereo presence for
mono audio signals.
Stereo Width Controls
The Stereo Width plug-in provides a variety of
controls for adjusting plug-in parameters.
Mode
The Mode control lets you specify the method by
which the Stereo Width plug-in will create the
artificial stereo field. Choices include the fol-
lowing:
Adjust Adjusts the existing stereo width of the
signal by M-S encoding, equalizing the S compo-
nent with the Low/Mid/High controls and
boosting/attenuating it with the Width control,
then M-S decoding back to stereo. The Delay
control delays the right signal relative to the left
for an additional widening effect (known as
“Haas panning”).
Comb Adds artificial width to the signal by M-S
encoding then adding a delayed version of the M
component to the S component. This creates a
comb filtering effect that shifts some frequen-
cies to the left and others to the right.
Phase In this mode the Low/Mid/High controls
set the centre frequencies of 3 phase shifters
which shift the relative phase of the left and
right channels, giving a much more subtle effect
than Comb mode.
Delay
The Delay control lets you specify the duration
of delay used in Phase mode (0–8 ms)
Width
The Width control sets the final width of the
generated stereo field.
Process Section Controls
The Process controls boost or cut the Low, Mid
and High-frequency bands of the generated ste-
reo signal.
Stereo Width Trim Section Controls
The Trim controls adjust the perceived cen-
ter/source of the generated stereo signal.
Level The Level control sets the volume of the
perceived center of the stereo signal.
Pan The Pan control sets the position left-to-
right of the perceived center of the stereo signal
