There is a large number of synthesis packages in use or development on the Linux platform at this time. The Linux Audio Developer's Simple Plugin API (LADSPA) attempts to give programmers the ability to write simple `plugin' audio processors in C/C++ and link them dynamically against a range of host applications.
Definitive technical documentation on LADSPA plugins for both host
and plugin writers is contained within copious comments in the ladspa.h
header file.
This SDK provides:
LADSPA_PATH
for LADSPA plugins. This program may be used
as the basis for further development.
