Agree, and Audacity has a linear cross-fade function precisely for
this. Zero crossing cuts will not remove a DC component across the
join unless the preceding half wavelength is exactly matched and
opposite to the following half wavelength.

This problem takes me all the way back to the origins of tape editing
with editing blocks which had an angled cutting slot. Even further
back, with editing optical film tracks which could only be spliced at
right angles, the cut would have to be "blooped" with blooping ink.
Magnetic film tracks would need blooping by softening the mag surface
with spicing cement. "Blooping" now means taking out naughty words,
but that's the origin of the term. Interesting to see how old problems
still remain with the latest technology.
