%description
rt_lpc is a light-weight application that performs real-time
LPC analysis and synthesis. It features the following:

- real-time LPC analysis
- real-time LPC synthesis
- visualization of original, predicted, and error waveforms
- visualization of vocal tract shape from LPC coefficients
- adjustable LPC analysis order
- adjustable synthesis pitch shift
- MIDI controlled pitch (hit 'm')
- lots of other choices (pitch pulse source selection, emphasis filter)
- STFT plot
- modular LPC library
