Mickey Hart (Grateful Dead Drummer) is digitally restoring
old analog recordings (Wood Guthrie, Leadbelly, etc) for the
Smithsonian Folkways label (they then sell the cd version). 
This was shown on TV (show called "Inventions" or something like that).
The interesting thing is that they showed a MACintosh (or windows PC??)
program that let them edit the music digitally. That is, find a pop, or
click  and then the software can be directed to edit it out.

My question is : Who can tell me the name of that software package?
                 What hardware is used to interface to the computer? 
                 What was (or can be) the host computer?

Thanks,
