ladspar is a Ruby module for using LADSPA plugins. Here's a short
example: 

---

require 'ladspa'
require 'narray'

# load the CMT library
cmt = LADSPA.load_library('cmt')

# get an instance of the amp_mono plugin
amp_mono = cmt.plugins.find {|p| p.label == 'amp_mono'}.instantiate(44100)

# The ports are Gain, Input, and Output.
amp_mono.ports[0].connect_port(1.5) # gain

input = NArray.sfloat(44100)
amp_mono.ports[1].connect_port(input)

output = NArray.sfloat(44100)
amp_mono.ports[2].connect_port(output)

amp_mono.activate if amp_mono.has_activate

# prep the input data ...

amp_mono.run

amp_mono.deactivate if amp_mono.has_deactivate
amp_mono.cleanup

This is the first release of ladspar; I consider it beta quality. I have
put it through its paces (more test code than swig code), but I am the
only one to have tested it. Nevertheless I think it is usable, and I am
eager to fix any bugs you may find.

Go grab it at http://rubyforge.org/projects/ladspar
