CHECK

KERN Check has become a crucial part of my final mastering chain because it goes far beyond a basic mono‑compatibility check. I use it to verify the integrity of my mix before printing the master, and it consistently gives me confidence that everything is translating as intended. The ability to isolate and confirm the side information is especially valuable — switching to the side channel lets me instantly confirm that my wide‑field elements, from ambience to spatial effects and stereo textures, are all present and behaving exactly as I mixed them.
