The only docs I could find about this is

<http://alsa.opensrc.org/Ladspa_%28plugin%29>

which provides an example:

pcm.ladspa {
    type ladspa
    slave.pcm "plughw:0,0";
    path "/usr/lib/ladspa";
    plugins [{
        label delay_5s
        input {
            controls [ 0.8 0.3 ]
        }
    }]
}

It's not clear at all from the syntax where the plugin is
supposed to go: capture, playback or both (!). Given the
context of the example it will be in at least the playback
path, maybe in both. 

<rant> This is one more example showing that the 
asoundrc syntax despite its baroque qualities is
missing its target. </rant>

Ciao,
