Wavetable

Superclass: FloatArray

A Wavetable is a FloatArray in a special format used by SuperCollider's interpolating

oscillators. Wavetables cannot be created by new.

Creation

*sineFill(size, amplitudes, phases)

Fill a Wavetable of the given size with a sum of sines at the given amplitudes and phases.

The Wavetable will be normalized.

size - must be a power of 2.

amplitudes - an Array of amplitudes for each harmonic beginning with the fundamental.

phases - an Array of phases in radians for each harmonic beginning with the fundamental.

Wavetable.sineFill(512, 1.0/[1,2,3,4,5,6]).plot;

*chebyFill(size, amplitudes, phases)

Fill a Wavetable of the given size with a sum of Chebyshev polynomials at the given amplitudes

for use in waveshaping by the Shaper ugen.

The Wavetable will be normalized.

size - must be a power of 2.

amplitudes - an Array of amplitudes for each Chebyshev polynomial beginning with order 1.

Wavetable.chebyFill(512, [0, 0, 1]).plot;

Wavetable.chebyFill(512, [0.3, -0.8, 1.1]).plot;

Instance Methods

plot(name, bounds)

Plot the Wavetable in a window. The arguments are not required and if not given defaults will be used.

name - a String, the name of the window.

bounds - a Rect giving the bounds of the window.

Wavetable.sineFill(512, [1]).plot;

Wavetable.sineFill(512, [1]).plot("Table 1", Rect.newBy(50, 50, 150, 450));

play(name)

Plays the Wavetable in a Mixer channel.

name - a Symbol or String giving the name of the mixer channel.

Wavetable.sineFill(512, [1]).play;

Wavetable.sineFill(512, [1]).play("Table 1");

asSignal

Convert the Wavetable into a Signal.

Wavetable.sineFill(512, [1]).asSignal.plot;
