<h1>LADSPA Plugin Manuals</h1>
<p>
This section contains detailed information, benchmarks and usage tips
for each available LADSPA plugin. It is intended to serve as a
reference manual for the TAP-plugins package.
</p>
<p>
If you are new to TAP-plugins, please read through the plugin manuals
to gain some basic understanding of these plugins. Some plugin
settings can be rather tricky and you may not achieve the desired
effect easily if you have not at least skimmed through the manuals, or
you are not an experienced audio engineer. You have been warned.
</p>
<p>
For every plugin, some general information is provided in a table. The
<b>Unique ID</b> is an identification number that each and every
LADSPA plugin must uniquely have. See the <a
href="http://www.ladspa.org">LADSPA homepage</a> for details. <b>I/O
ports</b> describes the number of input and output audio ports. A
plugin is mono if it has 1 input and 1 output, and it is stereo if it
has 2 inputs and 2 outputs. The <b>CPU usage</b> measures were
explained in <a href="general.html#metrics">a previous section</a>.
</p>
<p>
A plugin qualifies as <b>hard RT capable</b> (suitable for use in hard
realtime environments) if it satisfies all of the following:
</p>
<ul>
<li>it does not use <code>malloc()</code>, <code>free()</code> or
other heap management within its buffer processing functions;</li>
<li>does not call any library functions (except for functions in the
ANSI standard C and C math libraries);</li>
<li>does not access files, devices, pipes, sockets, IPC or any
other mechanism that might result in process or thread blocking;</li>
<li>the time needed to process a buffer can be approximated in
the form (A+B*SampleCount) where A and B depend on the machine and
host in use -- the time may not depend on input signals and plugin
state.</li>
</ul>
<p>
A plugin is capable of <b>in-place operation</b> if it does not get
confused when it is asked to use the same memory buffer for both input
and output sample data. Finally, the <b>run_adding() function</b> is
an optional buffer processing function described in the LADSPA
specification. When provided, this may make life of some hosts easier.
