Hi! I'm trying to get some tests with lpc done with csound5. The problem I have is: my csound5 doesn't have it's own lpanal, so I used lpanal of csound4.23.something. it runs fine and outputs its analysis-frames. But when I run a simple test, it only outputs to cracks with a lot of silence in between. My orchestra looks something like: [header] instr 1 ktim line 0, p3, p3 a1 buzz 15000, 110, 64, 1 ; function 1 is a sine GEN09 krmsr, krmso, kerr, kcps lpread ktim, "voice.lpc" aout lpreson a1 out aout endin The audio-material, which I analysed was simple speech. Am I doing something wrong? Should I be sure to use one of lpanal's options to get good input for lpread/lpreson?
