I am restoring a collection of 1200 LPs and am trying to understand how to configure WL to complete the task. Before I allow the needle to touch the surface of the record, I noticed that the VU meters are jumping around in the ‘Recording’ window in the sub- (-30db) range. There appears to be two other bars steady at about -39db. My desire is to reduced this rumble/hum (probably from both the turntable and pre-amp) to the -39db level.
I recorded/rendered a few minutes worth of this to play with. I’m assuming I should do this before I focus on the click/pop/crackle clean up of the LP.
When I do a 3D spectrum analysis I see a huge peak at 60Hz, so I assume I have AC hum issues. Sadly, the 3D analysis does not have a graticule for the Z plane, so it is rather difficult to determine quantitatively the amount of attenuation required.
Should I be using EQ to kill this, and how can I tell if it is ‘enough’ and not too much without the actual sound material/music rendered?
I toyed with DeBuzzer, but matching the pitch is somewhat subjective and it is unclear to me what the sequence for adjusting the various dials should be on the tool (how high before freezing, when is it ‘enough’).
Any help would be appreciated.
