Re: arsclist Thoughts on a "dream" manual declicker/deglitcher for 78 restoration (Windows-based software)

Well, yes and no and maybe. <laugh/>

Pristine Sounds 2000 illustrates how the manual declicking tool I
envision would work like from the end-user's point-of-view. But PS
2000 has two problems, the second one being fatal:

1) Its visualization interface could be improved. It is very easy to
   "miss the target" because the window is so damn small. Thus it
   takes a little longer than necessary to aim the cross-hairs on top
   of a click, and even here sometimes a miss occurs (Jaco illustrates
   how this interface could be greatly improved.)

2) Under-the-hood, the algorithm which PS 2000 uses to remove the
   click is based on frequency space editing and thus is no good for
   78 restoration as I've previously noted why.

   What should be done instead, when a click is selected in the
   frequency space window, this will simply flag the exact time where
   the click occurs and pass that time on to an underlying waveform
   editor algorithm which I have previously spec'ed.

   In essence, then, the frequency space map is simply used as a
   visualizer to help the end-user to quickly locate all the clicks
   and to quickly and easily pass the time locations of these clicks
   on to the robust internal waveform editor. No editing is actually
   done in the frequency domain.


Hope this helps to clarify things.
