Hi! This is possible. You have a simple choice: applyplugin, which comes with the ladspa_sdk - I think. This is really very simplistic. Another choice would be ecasound http://www.eca.cx/ecasound. Then there is still the ardour-KSI console interface, but that is not maintained, at the moment, again not 100% sure. Ecasound would be a good choice for a start, it support different file-formats (vai libsndfile) and different outputs jack, alsa, oss... Hope that helps!
