[sndtools] rt_lpc and formant spectrum estimation

Hi -

I'd like to use rt_lpc to estimate formant positions in a voice signal. 
It looks straightforward to get the LPC coefficients from the rt_lpc 
main library, but AFAIK there isn't a routine in rt_lpc to go from there 
to an estimated spectrum. Could anyone give me a hint about how to make 
that transformation?

Thanks in advance -
Dan
