NAME

       ladspalist - find LADSPA plugins info for use by SuperCollider

SYNOPSIS

       ladspalist

USAGE

       ladspalist | less

DESCRIPTION

       The  LADSPA  UGen  lets  you run any LADSPA plugin inside SuperCollider.  Run the ladspalist utility in a
       shell to find the info about the plugin you want.

       For example, glame lowpass iir with ID 1891:

         # 1891 Glame Lowpass Filter
         > k: Cutoff Frequency (0.0001 to 0.45)
         > k: Stages(2 poles per stage) (1 to 10)
         > a: Input
         < a: Output

       The meaning of the first two characters for each port are:

         '>' - input
         '<' - output
         'k' - controlrate
         'a' - audiorate

       Use it in SuperCollider:

         play{
           LADSPA.ar(
             1, 1891,
             1000+LFNoise1.kr(10, 800),
             2, WhiteNoise.ar(1!2)
           )
         }

       Note that the first arg is the number of output audio channels, then the UniqueID, the rest  is  all  the
       inputs in the same order as shown in ladspalist.  Currently, controlrate outputs are ignored.

       If the plugin doesn't provide the requested number of channels, the extra channels will be silenced.

       If the plugin provides more than requested number of channels, the extra channels will be ignored.

WARNING

       Some LADSPA plugins might not be real-time safe, if they allocate memory at initialization.
