Basically, right now there is lv2_jack_host, which is good for real time plugin hosting, but doesn't allow you to change the parameters of the plugin.

You also might be interested in lv2file, a CLI app I wrote to apply LV2 effects to files.  You can control plugin parameters and channel routing from the command line.  Right now it only supports audio+control input and audio output, but it might be a useful tool in your CLI suite for applying "effects" in the strictest sense to audio files.  Anyway, you can take a look at it here: http://jeremysalwen.github.com/lv2file/

Hope that helps!

Evening, all,

All this talk about LV2 has got me wondering. Is there any mechanism
planned to make LV2 plugins accessible to the CLI or via some kind of
API? Speaking as a blind CLI audio apps user, I find the move to ever
increasingly integrated GUIs (as opposed to, say, LADSPA) scary for the
prospect of accessibility, or even scriptability, for that matter. What
are your thoughts on the subject?

Cheers,
S.M.
