In many cases it can also be mixed into another composition. If mixing back into the same master, it is pretty transparent since the material missing that caused the phasing is in another stem. SpectraLayers (Pro) will also drill down two more levels of unmixing, but it is very dependent on the reverb usage in the master to get a pristine (or even suitable) track.

From that perspective, RX Standard would match that feature. Both of them took roughly 90 seconds to unmix stems from a song 7:30 in length. I did a quick test of this (RX 9 Advanced versus SpectraLayers Pro 9), and the unmix stem results were comparable on the same song using default presets. When you click "Separate" in the Rebalance window, it splits the audio into four stems vocal/bass/percussion/other as new tabs in the RX Editor. It is called "Music Rebalance" and you will find it referenced by same in the manual. I've only used RX 9 Standard for "fixing" problems (usually some kind of noise) in old recordings. I have not used the stem separator, other than to observe the function out of curiosity.
