I spent the week-end going through my collection of 70's and 80's
compilation albums of old jazz records remastered by John R.T. Davies and
Robert Parker.


I must say I am a bit impressed by the way they were able to suppress noise
and especially the crackle form the old 78's they used.


May anybody remember (or know) how they did that and what kind of machines
they used back in the analogue days?


All the best
