Low Frequency Oscillators (_LFOs_) are an important piece in any digital audio workstation or synthesizer. Topos implements some basic waveforms you can play with to automatically modulate your paremeters.
- <ic>sine(freq: number = 1, times: number = 1, offset: number= 0): number</ic>: returns a sinusoïdal oscillation between <ic>-1</ic> and <ic>1</ic>.
- <ic>sine(freq: number = 1, phase: number = 0): number</ic>: returns a sinusoïdal oscillation between <ic>-1</ic> and <ic>1</ic>.
- <ic>freq</ic> : frequency in hertz.
- <ic>times</ic> : output value multiplier.
- <ic>offset</ic>: linear offset.
- <ic>usine(freq: number = 1, times: number = 1, offset: number= 0): number</ic>: returns a sinusoïdal oscillation between <ic>0</ic> and <ic>1</ic>. The <ic>u</ic> stands for _unipolar_.
- <ic>phase</ic> : phase amount (adds or substract from current time point).
- <ic>usine(freq: number = 1, phase: number = 0): number</ic>: returns a sinusoïdal oscillation between <ic>0</ic> and <ic>1</ic>. The <ic>u</ic> stands for _unipolar_.
