The Mode control lets you specify the method by which the Stereo Width plug-in will create the artificial stereo field. Choices include the following:
Adjusts the existing stereo width of the signal by M-S encoding, equalizing the S component 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”).
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 frequencies to the left and others to the right.
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.
The Process controls boost or cut the Low, Mid and High-frequency bands of the generated stereo signal.
The Trim controls adjust the perceived center/source of the generated stereo signal.
The Pan control sets the position left-to-right of the perceived center of the stereo signal
