[linux-audio-user] Vocoder

Hi everybody! I've found a software Linux vocoder (http://www.sirlab.de/linux/download_vocoder.html) which is available both as a LADSPA plugin and a standalone program. I've got an old Pentium 166MMX with 64MB RAM which is unused, and i'd like to use it as a live vocoder. It would be cool to bring it on the stage, plug a keyboard and a microphone in its audio board(s), turn it on without any display, mouse or keyboard and have it already working as a vocoder. Unfortunately I have no idea of how to make it. I don't know how to make the vocoder (plugin or standalone) start and work automatically after the boot, possibly without having to start a graphical interface (which would be heavy for the poor P166 and totally unuseful, since there's no display). Any idea about how to realise such a thing? Bye, Lorenzo
