> Do you mean that you want a single repair covering the entire region, or something else?
1. I select a region in the recording, say 1sec.
2. I ask VS to make a series of contiguous small repairs to that region
My experiments show that a series of relatively small repair regions fit the overall shape of the waveform really well, don't significantly clip peaks, or otherwise mess with the recording. But they do remove those very small peaks that make up this sort of noise. The wider the repair the poorer the fit to the waveform hence wanting a series of contiguous small repairs.
But, obviously, even for a single second, this could be a lot of repairs. At 10 samples per repair @ 192kHz it's ~18k repairs and I can see this would be disruptive for the VS UI as it stands and would pretty much destroy the corrections list. I guess it means inventing a completely new class of repair...
I think what I'm asking for is the equivalent of very fine sandpaper. The sort we use to smooth a rough surface but without changing its shape in any way. I'm sure there are curve fitting algorithms that do this to remove sample noise, but it's not my field.
If I've still not explained myself properly, I apologise. I could provide an album where I've made a short section of these repairs by hand...
