| Just tested lpc herein csound5. While it's not working well, it works.
The lpanal utility is producing lpc analysis files.
lpreson is working OK. However, the pitch tracking output
of lpread (kcps) does not seem to be working well.
If you just use the bank of filters and ignore the rest, it
works.
The pole storage method of analysis is not working well,
use the default (filter coefficient method)
Here's an example
analysis:
csound -U lpanal pianoc2.wav pianoc2.lpc
CSD:
sr=44100
kr=4410
ksmps=10
nchnls=1
instr 1
ktim line 0, p3, p3
krmsr,krmso,kerr,kcps lpread ktim,"pianoc2.lpc"
asig buzz 100, 200, 30, 1
afil lpreson asig
out afil
endin
f1 0 16384 10 1
