While I agree that the zero crossing approach to editing involves an unnece=
ssary waste of time & effort, I have in fact made crossfade-less edits at t=
he zero crossing of true sine waves & there were no pops. That said, I ofte=
n make hundreds or even thousands of music edits a day & I would never in a=
million years subject myself to that amount of drudgery if I had to make t=
hem all at zero crossings. Life is way too short. The crossfade not only ma=
kes zooming in to near sample level unnecessary it also allows for a lot of=
useful creative or corrective edits. I find the equal power crossfade (log=
arithmic) smoother & more musical than the equal gain fade (linear) slope.
