Parent

PyoObject

Args
pitch: float or PyoObject, optional

Controls the speed, in the range 0 -> 1, of the variations. With values below 0.2, this object can be used as a low frequency oscillator (LFO) and above 0.2, it will generate a broad spectrum noise with harmonic peaks. Defaults to 0.25.

chaos: float or PyoObject, optional

Controls the chaotic behavior, in the range 0 -> 1, of the oscillator. 0 means nearly periodic while 1 is totally chaotic. Defaults to 0.5

stereo, boolean, optional

If True, 2 streams will be generated, one with the X variable signal of the algorithm and a second composed of the Y variable signal of the algorithm. These two signal are strongly related in their frequency spectrum but the Y signal is slightly out-of-phase. Useful to create alternating LFOs. Available at initialization only. Defaults to False.

FastSine

class FastSine(freq=1000, initphase=0.0, quality=1, mul=1, add=0)[source]

A fast sine wave approximation using the formula of a parabola.

This object implements two sin approximations that are even faster than a linearly interpolated table lookup. With quality set to 1, the approximation is more accurate but also more expensive on the CPU (still cheaper than a Sine object). With quality = 0, the algorithm gives a worse approximation of the sin function but it is very fast (and well suitable for generating LFO).

SumOsc

class SumOsc(freq=100, ratio=0.5, index=0.5, mul=1, add=0)[source]

Discrete summation formulae to produce complex spectra.

This object implements a discrete summation formulae taken from the paper ‘The synthesis of complex audio spectra by means of discrete summation formulae’ by James A. Moorer. The formulae used is of this form:

(sin(theta) - a * sin(theta - beta)) / (1 + a**2 - 2 * a * cos(beta))

where ‘theta’ and ‘beta’ are periodic functions and ‘a’ is the modulation index, providing control over the damping of the partials.

The resulting sound is related to the family of modulation techniques but this formulae express ‘one-sided’ spectra, useful to avoid aliasing from the negative frequencies.

Args
freq: float or PyoObject, optional

index: float or PyoObject, optional
