Here is the comparison of the piano stem extracted from
Who Are You. The top two tracks were extracted last night using "Cassiopeia." The lower two tracks were extracted this afternoon using "Phoenix." The Phoenix extraction is visibly cleaner than the Cassiopeia extraction and has more dynamics. Phoenix also sounds cleaner than Cassiopeia in isolation.
I don't know how great a difference it will make when all of the stems are put back together, but I am definitely glad to have the cleaner piano stem with which to work. Note that I had cleaned up some artifacts in the Cassiopeia extraction last night. What you see below includes my cleanup work on Cassiopeia. (Looks like I missed some 'junk' in the middle there.) The Phoenix extraction is untouched as received from LALAL.AI.
