PSP stereoController2 can be used in various situations:
unbalanced stereo image due to level difference between channels, e.g. in dual microphone stereo recordings

slight time alignment shift between channels

a track’s stereo image is too narrow or too wide for the mix

when the center instrument seems to be shifted to one side

virtually emulating an instrument’s location in the soundfield via combined level and delay panning

one or both channels have reversed polarity, or the channels are swapped

decoding a Mid-Side (M-S) encoded track into L/R stereo

reducing the stereo width of low frequencies, or making them mono, for proper speaker or subwoofer replay or for reliably cutting vinyl

widening stereo width of high frequencies for more ‘airy’ harmonics and spaciousness

fine adjustment of stereo imaging during the mastering process

A witch said,
* iLok License Manager isn't required to run.
* Our release loads faster and uses less memory than legit version.
