Cutting at zero crossings should solve the problem... But, do you just
check for zero crossings, or for zero crossings in one direction? I mean,
if you do one cut at a zero crossing where the signal goes from negative
to positive, and the other one where the signal goes from positive to
negative, then you can get a strong transient in a rejoined file: the
signal will "bounce" from the zero line.

If this does not help, about a short (1-3 ms) crossfade - unless it
interferes with your purpose.
