Hi,
I'm batch processing about 120 old masters in WAVLAB, recorded years
ago, before I knew anything about recording, at least relative to what I
know now.
It's been suggested that I should use the "Free Filter" to roll off
everything below 50k, since it's inaudible, although it still adds to
the overall volume. Fine.

My question is concerning the highs. Where should I apply the roll off
highs that won't affect the program material to the listener ? Or
doesn't it matter with the highs as much as on the lowest frequencies.
Is it okay to use the Free Filter on those also?

Thanks,
al
