dssiaudio — Processes audio using a LADSPA or DSSI plugin.

[Note] Note
plugin: Requires dssi4cs plugin


[aout1, aout2, ..., aout9] dssiaudio ihandle, [ain1, ain2, ..., ain9]


Plugin opcode in dssi4cs.

dssiaudio generates audio by processing an input signal through a LADSPA plugin.


ihandle - handle for the plugin returned by dssiinit


aout1, aout2, etc - Audio ouput generated by the plugin

ain1, ain2, etc - Audio provided to the plugin for processing

dssiaudio runs a plugin on the provided audio and produces audio output. Currently upto four inputs and outputs are provided. You should provide signal for all the plugins audio inputs, otherwise unpredictable results may occur. If the plugin doesn't have any input (e.g Noise generator) you must still provide at least one input variable, which will be ignored with a message.

Only one dssiaudio should be executed once per plugin, or strange results may occur.


Here is an example of the dssiaudio opcode. It uses the file dssiaudio.csd.
