lposcilsa2

lposcilsa2 — Read stereo sampled sound from a table with looping and high precision.

Description

lposcilsa2 reads stereo sampled sound from a table with looping and high precision.

Syntax

ar1, ar2 lposcilsa2 aamp, kfreqratio, kloop, kend, ift [,iphs] 

Initialization

ift -- function table number

iphs -- initial phase (in samples)

Performance

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.
