0001 If you want to write a new effect that should be usable from you Phonon
0002 application, I encourage you to use LADSPA. This plugin API was designed
0003 especially to make the effect usable for as many audio
0004 libraries/frameworks/applications as possible. The result is that your plugin
0005 can then be used by more than only one backend.

0007 It is not coincidence, that the effects API of Phonon is modeled after LADSPA,
0008 since those are the cross-framework plugins...
