process_sample()

double MayaFlux::Nodes::Generator::Phasor::process_sample ( double  input = 0. )

overridevirtual

Processes a single input sample and generates a phasor sample.

Parameters

input

Input sample (used for modulation when modulators are connected)

Returns

Generated phasor sample (ramp from 0 to amplitude)

This method advances the generator's phase and computes the next sample of the phasor ramp, applying any modulation from connected nodes.

Implements MayaFlux::Nodes::Node.
