Re: [ARSCLIST] Preservation media WAS: Cataloguing still :-)
So far, no AME tapes have crossed the transum here.
Do you have any estimate as to how many AME machines were used, or how many master tapes made with
AME exist? AME was used for duplicator masters starting with the Ampex 3200D/3300 for quarter-inch
duped at 60IPS. I don't know if AME survived into the 8-track duping era. Quarter-track masters were
made on 1/2" 4-track tapes, with AME. At Fine Recording, masters were made at 7.5IPS (same speed as
the dupes would be) and duplicating was done at 30IPS (4x) and later 60IPS (8x). Some places would
master at 15IPS and play master at 60IPS and record dupes at 30IPS.
One man's opinion here -- the only really good-sounding mass-duped reels were the early 2-tracks
that were duped at 2x.

Hi Richard:
I don't even know if this is possible, but did you ever try "de-NAB'ing" that CD and then AME'ing
it? Could you do that in Samplitude? I'd think you might want to make an analog transfer, 24-bits,
at a relatively low peak level. Then reverse-NAB it. Then AME it, then normalize for peak value.
Result better or worse?

Better but not perfect with AME added -- they tried to de-AME it with mastering EQ, I think, so
it's very variable, but the de-AME filter in Samplitude (that I made in an equalizer helped a lot.
Remember, AME is a curve on TOP of NAB-15.
I have designed an AME filter with contemporary components and it matches the two AME equalizers I
could model and Jay McKnight's published curve pretty well. I have a set of three and I sold one
to another engineer and a third engineer built a set from my plans which are on my Web
site...somewhere. Search the Tips and Notes Blog for AME is probably fastest.
Cheers,
