 S channel allows me to increase the level of the S signal at low frequenci=
es only. The end result is that I have widened the image at low frequencies=
 but not at high frequencies. For many recordings made with coincident pair=
s, that's all that is needed to re-align the fundamental and lower harmonic=
s of a sound source with its higher harmonics.

Perhaps a formula could be devised to specify the optimal bass shuffling cr=
ossover frequency and shelf amplitude for stereo arrays, depending on the m=
ic spacing?
