poscil3

poscil3 --  High precision oscillator with cubic interpolation.

Description

High precision oscillator with cubic interpolation.

Syntax

ar poscil3 kamp, kcps, ifn [, iphs]

kr poscil3 kamp, kcps, ifn [, iphs]

Initialization

ifn -- function table number

iphs (optional, default=0) -- initial phase (in samples)

Performance

ar -- output signal

kamp -- the amplitude of the output signal.

kcps -- the frequency of the output signal in cycles per second.

poscil3 uses cubic interpolation.

Examples

Here is an example of the poscil3 opcode. It uses the files poscil3.orc and poscil3.sco.
