Hello all,
Seems to be really dead this whole liquidsoap-thing doesn't it? Anyway,
if there's anybody who can help me in integrating my
sidechain-compressor into my liquidsoap-script to do what i described in
my previous mail here's what i get when i type:
hserver:~# liquidsoap -h ladspa.sidechaincompressor
