Description:

DSSI (pronounced "dizzy") is an API for audio processing plugins,
particularly useful for software synthesis plugins with user
interfaces.

DSSI is an open and well-documented specification developed for
use in Linux audio applications, although portable to other
platforms. It may be thought of as LADSPA-for-instruments,
or something comparable to VSTi.

DSSI consists of a C language API for use by plugins and hosts,
based on the LADSPA API, and an OSC (Open Sound Control) API for
use in user interface to host communications. The DSSI
specification consists of an RFC which describes the background
for the proposal and defines the OSC part of the specification,
and a documented header file which defines the C API.

DSSI is Free Software. The DSSI header file is provided under
