Sound looping 'pop' (sugarcube 2.11.0)

Yes, I realised I've asked this before, but it was one part of a double question and never really got discussed much.

I can't be the only one who uses loops on their audio tracks so I'm putting this out to anyone who's discovered a way to mask the little 'pop' noise you hear when the sound clip ends, then starts its next loop.

I use Audacity to create my sound files and did try fading out the clip, but this only accentuates the split.

Any ideas appreciated.
