[PD] polynomial pairs in lpc filter

hi list,

this is more of a general DSP question...

i am working on an LPC playback and mangling system for axoloti. i have
most of it working and i am now trying to shift formants in the filter to
change voice character. i found functions to convert reflection
coefficients into polynomial pairs and presumably i should be able to shift
filter frequencies in this representation of the data. unfortunately i have
no clue how to do that. any hints, papers, code snippets etc. are very
welcome.

or if someone wants to take the time to explain, you are of course more
then welcome

thanks for any suggestions
