Many audio synthesis and recording packages are in use or in development on Linux. These work in many different ways. LADSPA provides a standard way for `plugin' audio processors to be used with a wide range of these packages.
For instance, this allows a developer to make a reverb program and bundle it into a LADSPA `plugin library.' Ordinary users can then use this reverb within any LADSPA-friendly audio application.
