saw~

Antialiased sawtooth oscillator

Description

saw~ generates a sawtooth wave whose component frequencies are resistant to aliasing.

Arguments

Name	Type	Opt	Description
initial-frequency (Hz)	int or float	opt	Sets the initial frequency of the oscillator. The default is 0.

Messages

int	frequency (Hz) [int]	In left inlet: Sets the frequency of the oscillator.
float	frequency (Hz) [float]	In left inlet: Sets the frequency of the oscillator.
signal		In left inlet: Sets the frequency of the oscillator. In right inlet: (optional) A sync signal. When the control signal crosses from below 0.5 to above 0.5, the oscillator resets itself. A phasor~ object works well for this purpose. The classic use is to set this control signal to your fundamental frequency and "sweep" the left frequency input in a range somewhere several octaves higher than the fundamental.
synctrig	trigger-value [float]	Sets the value which an input signal crosses at which the oscillator will reset itself.

Output

signal: An antialiased sawtooth waveform. An ideal, straight-line sawtooth wave generated in a computer contains aliased frequencies that can sound irritating. saw~ produces a nice, analog-esque output waveform.
