First a small remark: the type="nofade"/"fade" does not seem to be used in your script. Liquidsoap doesn't recognize anything like that: all it does is reacting to the liq_fade_* and liq_start_next metadata. > def crossfade(~start_next,~fade_in,~fade_out,s) > s = fade.in(duration=fade_in,s) > s = fade.out(duration=fade_out,s) > fader = fun (a,b) -> add(normalize=false,[b,a]) > cross(fader,s) > end You made a good point about this function taken from our wiki: the start_next parameter is unused. In normal times I'd have advised you to fix it on our wiki, but now we're moving to another system for documentation, soon online. I'll fix it there. As you correctly said, the last line should be cross(duration=liq_start_next,fader,s). > Now, at first impression, liq_fade_out is not correct. In almost all > cases, some 4-5 seconds overlap i hear. The overlap is controlled by start_next, not fade_out. Cross_fade is only the duration of the fading, that is re-shaping of the enveloppe of an end of track. > If i add "liq_start_next" parameter to META (annotate), all is ok. That makes sense. In the end, you understood the problem quite well, I'm just confirming everything you said :) > Problem TWO > if i use function > radio = crossfade(start_next=1., fade_in=0., fade_out=0., radio) > this is response from liquidsoap console log: > ... Waiting for "[EMAIL PROTECTED]" to be ready... > ... Waiting for "[EMAIL PROTECTED]" to be ready... > etc Thanks a lot. You spotted a bug. The fade.out() operator fails to declare itself as ready when its duration is zero. I've fixed it on SVN. If you don't want to rebuild from SVN, you can safely use fade.out=0.0001 -- smaller than that may result in a rounding to 0.
