lposcilsa2 — 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, 2 = an octave up). Only integers are allowed
kloop -- start loop point (in samples)
kend -- end loop point (in samples)
lposcilsa2 is the same as lposcilsa, but no interpolation is implemented and only works with integer kfreqratio values. Much faster than lposcilsa, it is mainly intended to be used with kfreqratio = 1, being in this case a fast substitute of soundin, since the soundfile must be entirely loaded in memory.
