Hi, i´m using liqidesoap since some weeks and i like the reliability and encoding quality.
Now i play with crossfade settings.
current i use following settings:
("crossfade", "8"),
   ("crossfade_fadein", "1"),
   ("crossfade_fadeout", "1"),
   ("crossfade_mode", "normal"),
   ("replay_gain", "1"),
If i use "smart", no really good crossfade as result.

Do you use the crossfade features and which settings you use?
