AutoLPC is not a real-time interface, but merely formats parameters and sends them out to the LPC analysis package included in RTcmix.
Most of the fields are described in the lpc documentation online. The 'link' buttons allow you to use the interface to automate cross-synthesis or not.
Usage:
autolpc
Problems / Bugs:
The LPC analysis instruments are by nature buggy, and always have artifacts. A port of the NeXTStep LPCView application is in order so you can actually edit the datasets.
