poscil3

poscil3 — High precision oscillator with cubic interpolation.

Description

High precision oscillator with cubic interpolation.

Syntax

ares poscil3 kamp, kcps, ifn [, iphs]
kres poscil3 kamp, kcps, ifn [, iphs]

Initialization

ifn -- function table number

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

Performance

ares -- 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 file poscil3.csd.
