I tried to use the implemented lpread-lpreson pair but the audio quality
is very bad also when using a high sampling rate. Actually it is not
usable for music. At the end of 80s I used an MS-DOS real mode version
of csound adapted by MTU which was able to give a very good synthesis at
low sr too. I'm asking why.

Here is a simple orc/sco example:

;****** lp.orc

        sr = 20000
        kr = 2000
 ksmps = 10

 instr 1
ktime line 0, p3, p3
krmsr,krmso,kerr,kcps   lpread  ktime, p4
avoice buzz krmso, kcps, int(sr/880), 1
aunvoc rand krmso
asig = (kerr < .3 ? avoice : aunvoc)
aout lpreson asig
        out     aout*.35
        endin
;-------------------------------

;*********** lp.sco

f1 0 8193 10 1
i1 0 1 1
i1 + . 2
i1 + . 3
e

;-------------------------

p4 chooses the analisis file number. The analisis files must be named
lp.
for example
lp.1
lp.2
lp.3
etc.
