Thank heavens we don't have to do it that way any more - if you look at the film you will see four splices go past in a second at one point. The length of excised material is about 4mm per click - that's about 1% of a second at 15 ips, or a 4% shift in tempo. Add to that the propensity for some sounds to "bump" over the edit and my nostalgia has faded to zero.

John RT Davies developed a system of blanking clicks by scraping oxide off the tape at exactly the peak of the click, and taught it to me. It worked well, although it could be laborious, but its cardinal virtue was that it left the timebase unchanged.

When I went over to digital editing, I was forced to return to cut-and-shut techniques initially, but these could be made much less invasive by the ability to both see the click and match the waveform so that the edit did not bump - this meant that less material was lost. Eventually, CEDAR manual declick and dethump enabled disturbances to be removed so well that there is no sign of their having been there in the first place, and without losing wanted material.
