Dan & all,

On a Mac using Peak LE, I tried using the crossfade/ linear blend
method via Preferences, Blending, 30 ms.  It didn't work.  And nor
did a setting using zero crossings.  Then I tried randomly chopping
out some bits from a half minute audio track in Peak, lots of clicks
at the cuts.

Then opened this clicky file in Izotope RX and used the Declicker
function, just selected the whole track and applied the declicker and
like magic all the clicks disappeared!
