LADCCA stands for Linux Audio Developer's Configuration and Connection API.
It is a session management system for audio applications on GNU/Linux. It
understands the JACK low latency audio API and the ALSA MIDI sequencer
interface. The system is comprised of a server program, @command{ladccad},
an application library, libladcca, and a command line control program,
@command{laddca_control}. The server and clients communicate over TCP
sockets. There are three kinds of clients: normal clients (audio
applications), user interfaces for the server, and connection patchbays.
In order to describe the system, we should introduce some terminology. First of all, the server is the @command{ladccad} server program, an omni-present marshaller and database for storing arbitrary application data. The library is the `libladcca' shared library. It contains all the functions that an application uses to communicate with the server and take part in the system. Such an application is called a client.
The server deals with things in terms of collections of clients, called projects. A project has a unique string name, a current directory and a list of clients that are in that project. The server can have one client that is a server interface that allows the user to control the server. There is one server interface included with the system, the @command{ladcca_control} program.
