Spectral comparison of tri~ and an ideal triangular wave
Antialiased triangular oscillator
| Name | Type | Opt | Description |
|---|---|---|---|
| initial-frequency (Hz) | int or float | First argument sets the initial frequency of the oscillator. The default is 0. Second argument sets the duty cycle. The default is 0.5. |
| int | frequency (Hz) [int] |
In left inlet: Sets the frequency of the oscillator. In middle inlet: Sets the duty cycle of the oscillator. Signal is wrapped into the range 0-1. A value of 0.5 will produce a triangular wave that spends equal amounts of time sloping positively and negatively. |
| float | frequency (Hz) [float] |
In left inlet: Sets the frequency of the oscillator. In middle inlet: Sets the duty cycle of the oscillator. Signal is wrapped into the range 0-1. A value of 0.5 will produce a triangular wave that spends equal amounts of time sloping positively and negatively. |
| signal | In left inlet: Sets the frequency of the oscillator. In middle inlet: Sets the duty cycle of the oscillator. Signal is wrapped into the range 0-1. A value of 0.5 will produce a triangular wave that spends equal amounts of time sloping positively and negatively. 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 "sweep" this control signal in a frequency range somewhere at least three or four octaves higher than the fundamental frequency. |
