Not that my opinion should hold any weight...

For Wav Composer Not Toilet's sampler module, I created a zero-crossing
"detector" which would look N samples either side of loop points etc
for the nearest sample to zero. It never really worked as well as I
expected, always always needed x-fades as well...

then there was bi-directional looping which you could specify N samples
to jump hopefully to prefent than phase mirroring which is even worse.

I think the only time zero-crossings are any good is in hand-crafted
cutting of (very) simple waveforms.
