The '''Linux Audio Developer's Simple Plugin API (LADSPA''') is an application programming interface (API) standard for handling audio filters and audio signal processing effects, licensed under LGPL-2.1-or-later. Originally designed through consensus on the Linux Audio Developers mailing list, it now works on a variety of platforms. It is used in many free audio software projects, and there is a wide range of LADSPA plug-ins available.
