LADSPA effects are supported in realtime and rendered mode for audio. The LADSPA plugins you get from the internet vary in quality. Most can not be tweeked in realtime very easily and work better when rendered. Some crash and some can only be applied to one track due to a lack of re-entrancy. Although Cinelerra implements the LADSPA interface as accurately as possible, multiple tracks of realtime, simultaneous processing go beyond the majority of LADSPA users. LADSPA effects appear in the audio folder as the hammer and screwdriver, to signify that they are Plugins for GNU/Linux Audio Developers.

LADSPA Effects are enabled merely by setting the “LADSPA_PATH” environment variable to the location of your LADSPA plugins:
or putting them in the “`/usr/lib/cinelerra’” directory.
If you use Debian, you can get a lot of plugins using apt:
“apt-cache search ladspa”
“apt-get install jack-rack cmt blop swh-plugins”
