-/* 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).
-
-   For audio it is generally assumed that 1.0f is the `0dB' reference
-   amplitude and is a `normal' signal level. */

-
-   (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. */

-/* Plugin Port Range Hints:
-
-   The host may wish to provide a representation of data entering or
-   leaving a plugin (e.g. to generate a GUI automatically). To make
-   this more meaningful, the plugin should provide `hints' to the host
-   describing the usual values taken by the data.
-
-   Note that these are only hints. The host may ignore them and the
-   plugin must not assume that data supplied to it is meaningful. If
-   the plugin receives invalid input data it is expected to continue
-   to run without failure and, where possible, produce a sensible
-   output (e.g. a high-pass filter given a negative cutoff frequency
-   might switch to an all-pass mode).
-
-   Hints are meaningful for all input and output ports but hints for
-   input control ports are expected to be particularly useful.

-/* Accessing a Plugin: */
-
-/* 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. */
