dsp::simple_oscillator Struct Reference

#include <osc.h>

Inheritance diagram for dsp::simple_oscillator:

Public Member Functions
void	reset ()
	Reset oscillator phase to zero.
void	set_freq (float freq, float sr)
	Set phase delta based on oscillator frequency and sample rate.
void	set_freq_odsr (float freq, double odsr)
	Set phase delta based on oscillator frequency and inverse of sample rate.
void	step ()
	Make one phase increment.
float	get ()
	Make one phase increment and return a value from -0.5 to 0.5.

Public Attributes
uint32_t	phase
	Phase (from 0 to 0xFFFFFFFF).
uint32_t	phasedelta
	Per-sample phase delta (phase increment), equal to 2^32*freq/sr.

Detailed Description

Very simple, non-bandlimited saw oscillator. Should not be used for anything else than testing/prototyping. Unless get() function is replaced with something with "proper" oscillator code, as the frequency setting function is fine.
