Thread Name: Tech: Removing hum from old tapes
Subject: RE: Tech: Removing hum from old tapes
The reafir thing I mentioned is an example of a subtractive process. You find a piece of tape which just has 'hum' in it and save that in the filter. You then subtract it from the whole.

It does a decent job.

I recorded something a few weeks ago and the result had a large amount of background hum. If you are interested I could probably do you a 'before' and 'after' to demonstrate.
