It appears that sometimes, when switching tracks, Volume Leveling now "hangs" sometimes:
When switching tracks, a small part at the beginning of the next track is being played at a louder volume, then very soon the playback volume "normalizes" again. I cannot reliably reproduce this, but when I wait long enough, I will notice it on some switches. It sounds like Volume Leveling is simply disengaged during the track switch, and the re-engaged. This fits with my observation that a small amount of time will pass between ticking Volume Leveling in the DSP Studio and the volume adjusting.
This happens to me too....
