I picked up the elements package, and I have tried the de-clip function on some of my first digital recordings from my early taping days back in '93. Back then I did not even have internet (I don't know if DATheads was even started back then), so I didn't know how to do stuff. I used a crappy Sony microphone with my Denon DTR-80P, and unfortunately I used the high setting for the mic preamp on the recorder. So those recordings are all brickwalled like crazy...
So, long story short, these recordings are of course never going to sound great, but the de-clip function works great to recreate the dynamics of the recordings. I never though I would ever listen to them again, but now they sound pretty decent considering my equipment.
I am pretty amazed that it is possible to do this after 25 years... If you do do have brickwalled recordings, I would definitely recommend trying it
