Quick update, I messed up one of the Declipper settings which makes a big difference...
I am using the Californication song by Red Hot Chili Peppers, as it is really easy to hear the distortion and leftover grain from incorrect settings with the Lakes or North plugin. The settings I used are as follows:
[Declipper]
Amount of peak samples to remove - long term=0.310000002
Amount of peak samples to remove - short term=0.620000005
Analog input=0
Clipped if below short term margin=0.270000011
Clipped if below short term margin Enabled=0
Clipping straight line margin=0.449999988
Declip if (type)=3
Declip if type 4 long term margin=0.920000017
Definitely clipped if below (relative)=0.970000029
Do not allow restored peaks to be lower than clipped signal=0
Do not reconstruct if reconstructed signal resembles original - texture threshold=0.029999999
Do not reconstruct if reconstructed signal resembles original - threshold=0.029999999
Dynamically increase maybe clipped level=1
Dynamically increase probably clipped level=1
Enabled=1
MP3 input=1
MP3 margin=0.925000012
MP3 number of samples=1
Maximum expected distortion level=1
Maximum restored peak=4
Maybe clipped if below (relative)=0.670000017
Not clipped if below (absolute)=2040
Only declip if clipping histogram spike is symmetrical=0
Only declip if tilt can be determined=1
Probably clipped if below (relative)=0.800000012
Quality=100
Reduction precision=0.99
Tilt default level=0
Tilt level detection enabled=1
Tilt maximum adjustment per measurement=0.027777778
Tilt maximum level=0.25
Tilt minimum level=-0.25
Veil after spike down speed (dB/ms)=1.159999967
Veil margin=0.899999976
Veil normal down speed (dB/ms)=0.439999998
Veil speed drop time reduction time after spike (ms)=1.620000005
