[Icecast] how to have fade in/out?

[simone dal maso]

Hello!
I use icecast2 and deefuzzer for my streaming. do you know how can I
obtain an automatic fade of a song when it ends with a silence? if the
mp3 finish with 3 4 seconds of silence, is it possible to remove it
automatically?
deefuzzer is not able to do it, can icecast2 make this? some ideas?
thank you!
