-/* Overview:
-
- There is a large number of synthesis packages in use or development
- on the Linux platform at this time. This API (`The Linux Audio
- Developer's Simple Plugin API') attempts to give programmers the
- ability to write simple `plugin' audio processors in C/C++ and link
- them dynamically (`plug') into a range of these packages (`hosts').
- It should be possible for any host and any plugin to communicate
- completely through this interface.
-
- This API is deliberately short and simple. To achieve compatibility
- with a range of promising Linux sound synthesis packages it
- attempts to find the `greatest common divisor' in their logical
- behaviour. Having said this, certain limiting decisions are
- implicit, notably the use of a fixed type (LADSPA_Data) for all
- data transfer and absence of a parameterised `initialisation'
- phase. See below for the LADSPA_Data typedef.
-
- Plugins are expected to distinguish between control and audio
- data. Plugins have `ports' that are inputs or outputs for audio or
- control data and each plugin is `run' for a `block' corresponding
- to a short time interval measured in samples. Audio data is
- communicated using arrays of LADSPA_Data, allowing a block of audio
- to be processed by the plugin in a single pass. Control data is
- communicated using single LADSPA_Data values. Control data has a
- single value at the start of a call to the `run()' or `run_adding()'
- function, and may be considered to remain this value for its
- duration. The plugin may assume that all its input and output ports
- have been connected to the relevant data location (see the
- `connect_port()' function below) before it is asked to run.
-
- Plugins will reside in shared object files suitable for dynamic
- linking by dlopen() and family. The file will provide a number of
- `plugin types' that can be used to instantiate actual plugins
- (sometimes known as `plugin instances') that can be connected
- together to perform tasks.
-
- This API contains very limited error-handling. */

-/* Fundamental data type passed in and out of plugin. This data type
- is used to communicate audio samples and control values. It is
- assumed that the plugin will work sensibly given any numeric input
- value although it may have a preferred range (see hints below).

- amplitude and is a `normal' signal level. */

- satisfy all of the following:
-
- (1) The plugin must not use malloc(), free() or other heap memory
- management within its run() or run_adding() functions. All new
- memory used in run() must be managed via the stack. These
- restrictions only apply to the run() function.
-
- (2) The plugin will not attempt to make use of any library
- functions with the exceptions of functions in the ANSI standard C
- and C maths libraries, which the host is expected to provide.
-
- (3) The plugin will not access files, devices, pipes, sockets, IPC
- or any other mechanism that might result in process or thread
- blocking.
-
- (4) The plugin will take an amount of time to execute a run() or
- run_adding() call approximately of form (A+B*SampleCount) where A
- and B depend on the machine and host in use. This amount of time
- may not depend on input signals or plugin state. The host is left
- the responsibility to perform timings to estimate upper bounds for
- A and B. */

- the plugin receives invalid input data it is expected to continue

- might switch to an all-pass mode).

-/* The exact mechanism by which plugins are loaded is host-dependent,
- however all most hosts will need to know is the name of shared
- object file containing the plugin types. To allow multiple hosts to
- share plugin types, hosts may wish to check for environment
- variable LADSPA_PATH. If present, this should contain a
- colon-separated path indicating directories that should be searched
- (in order) when loading plugin types.
-
- A plugin programmer must include a function called
- "ladspa_descriptor" with the following function prototype within
- the shared object file. This function will have C-style linkage (if
- you are using C++ this is taken care of by the `extern "C"' clause
- at the top of the file).
-
- A host will find the plugin shared object file by one means or
- another, find the ladspa_descriptor() function, call it, and
- proceed from there.
-
- Plugin types are accessed by index (not ID) using values from 0
- upwards. Out of range indexes must result in this function
- returning NULL, so the plugin count can be determined by checking
- for the least index that results in NULL being returned. */
