Once again, I suggest ecasound and LADSPA. To me it seems tailor-made for what
you want to do.

Download the ladspa sdk from www.ladspa.org, build and install it.
Then download ecasound from www.eca.cx, build it, install it, skim the manual.
(To use double-precision audio data you'll have to change the two typedefs I
mentioned in my previous mail.)

Then your entire framework consists of a simple shell command:

ecasound -i:your_input_device -o:your_output_device \
         -el:some_ladspa_plugin,parameter1,parameter2,...

You could use any of the example plugins with the LADSPA SDK as your "dummy
routine.
"
