Re: [Savonet-users] LADSPA howto?

Hi,

Indeed, I don't remember having a good page about ladspa in our doc.
We should fix that. It's simple:

The LIQ_LADSPA variable is only useful for disabling ladspa, it's
enabled by default. The PATH variable is also only useful if the
default path is not enough for you.

With my liquidsoap compiled with ladspa, I can simply do "liquidsoap
--list-plugins | less" and I find there lots of ladspa.* operators:
ladspa.amp_mono, ... ladspa.artificial_latency, etc and also
ladspa.fastlookaheadlimiter.

The --list-plugins is useful to avoid guessing the operators' names.
Notice however that the ladspa.* operators are omitted from the
reference in the doc because there are too many of them.

Have fun!
