Description

High precision oscillators. poscil3 and lposcil3 use cubic interpolation.

Initialization

ifn - function table number

iphs(optional) - initial phase (in samples)

Performance

ar - output signal

kamp - amplitude

kcps - frequency

poscil (precise oscillator) is the same as oscili,but allows much more precise frequency control, especially when using long tables and low frequency values. It uses floating-point table indexing, instead of integer math, like oscil and oscili. It is only a bit slower than oscili.
