Hello Paul, Hello Alls,

Some more precisions. The shellacs was digitized with a stereo cartridge, =
et nominal speed. A precision: we have no option to select the better =
shellac, we have only relocated the three we have digitized.

The digitized signal was processed as follows:

- Reduction to mono selecting the best canal, not mixing the two canals.
- Manual declicking (with pencil) for the stronger events.

The I have a copy semi-declicked to work with.

The tests I've made for whole declicking process is good. The one for =
decrackling is  just standard on two of the three shellacs.

The tests for surface noises and rumble are the worst. The tests was made =
with the manual hard events declicking made.

I refresh our memory reminding that tests have been made with a CEDAR 3000 =
system without significative results...

Regards.
