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.
