A few days ago I found a module called module-ladspa-sink ,
and it can be enabled by adding the following code to the
/etc/pulse/default.pa file:

.ifexists module-ladspa-sink.so
.nofail
load-module module-ladspa-sink sink_name=compressor plugin=sc4m_1916 label=sc4m control=1,1.5,401,-30,20,5,12
.fail
.endif

It works, but I was trying to figure out what exactly
control=1,1.5,401,-30,20,5,12 means. There's a link
(http://plugin.org.uk/ladspa-swh/docs/ladspa-swh.html#tth_sEc2.92),
where you can find some documentation on the sc4m_1916 plugin,
but actually I don't really know which of the values corresponds
to the specific options. In the link, there's 9 parameters,
and in the code above, there's 7 I think.

Is there someone who could cast a little light on the control numbers?
