lposcilsa — Read stereo sampled sound from a table with looping and high precision.
ar1, ar2 -- output signal
aamp -- amplitude
kfreqratio -- multiply factor of table frequency (for example: 1 = original frequency, 1.5 = a fifth up , .5 = an octave down)
kloop -- start loop point (in samples)
kend -- end loop point (in samples)
lposcilsa is the same as lposcila, but works with stereo files loaded with GEN01.
