Hi John,
The PR for the crossfade rewrite is pending here:
https://github.com/savonet/liquidsoap/pull/705
I'm a bit reluctant to merge it right away because it's a significant chunk
of change and I haven't played with it for a while. However, last I checked
it was looking pretty good.
Perhaps you could give it a try? Essentially, the only thing you should
have to change is that the simple `crossfade` is removed and
`smart_crossfade` is renamed `crossfade`.
