Hello,
sorry for the late reply, but due to a hack of my server (an ftp account),
I was a bit buzy.
I wish to thank others people helping me, but David's solution
look more easy for the newbie I'am.
Unfortunately something is not clear for me.
(let me know if i'm wrong)
- "cross" can make transition only between 2 differents tracks of the same
source ?
- to make transition between 2 differents sources I'have to use "transition"
function ?
(in my case it's transition between 2 differents sources)
You propose to replace my "crossfade", ok
but what's happen to my "transition" definition ?
Do i need it ? because your "def crossfade" seems usable "as is". (??)
YOUR CROSSFADE
mixin_jingle = single(...)
def crossfade(a,b)
sequence([ fade.final(duration=8.,a),
mixin_jingle,
fade.initial(duration=7.,b) ])
end
MY TRANSITION
def transition(j,a,b)
add(normalize=false,
[ fade.initial(b),
sequence(merge=true,
[blank(duration=1.),j,fallback([])]),
fade.final(a) ])
end
How to rewrite my "radio" definition?
radio = fallback(track_sensitive=false,
transitions=[ crossfade, transition(????????) ],
[ tracks, tracksmix ])
I hope you understand my twisted questions.
Ton of Thanks
Fred
