|
|
A set of tools for generating and altering sigmas in ComfyUI.
|
|

|
Nodes Description
|
|
|
|
SigmaWaveFormNode
|
|
The SigmaWaveFormNode generates a variety of waveforms with adjustable parameters such as
|
|
amplitude,
|
|
frequency,
|
|
damping factor,
|
|
and waveform type.
|
|
|
|
It supports multiple waveform types,
|
|
including sine,
|
|
sawtooth,
|
|
stepped,
|
|
square,
|
|
random,
|
|
triangle,
|
|
and rectangular waves.
|
|
|
|
The node also allows for optional Fourier transformation and uni-directional output.
|
|
|
|
Parameters:
|
|
|
|
steps: Number of steps in the waveform.
|
|
amplitude: Amplitude of the waveform.
|
|
frequency: Frequency of the waveform.
|
|
damping_factor: Damping factor applied to the waveform.
|
|
waveform_type: Type of waveform (sine, sawtooth, stepped, square, random, triangle, rectangular).
|
|
enable_damping: Boolean to toggle damping.
|
|
min_sigma: Minimum sigma value for the waveform.
|
|
apply_fourier: Boolean to toggle Fourier transformation.
|
|
horizontal_length: Proportion of each horizontal segment length in the stepped waveform.
|
|
enable_unidirectional: Boolean to toggle uni-directional transformation.
|
|
|
|
|
|
SigmaWaveFormNodeAdvanced
|
|
The SigmaWaveFormNodeAdvanced extends the functionality of the standard waveform generator by supporting the blending of two different waveforms.
|
|
It provides additional parameters for the second waveform and a blend factor to control the mixture of the two waveforms.
|
|
|
|
Parameters:
|
|
|
|
steps: Number of steps in the waveform.
|
|
amplitude1: Amplitude of the first waveform.
|
|
frequency1: Frequency of the first waveform.
|
|
waveform_type1: Type of the first waveform.
|
|
amplitude2: Amplitude of the second waveform.
|
|
frequency2: Frequency of the second waveform.
|
|
waveform_type2: Type of the second waveform.
|
|
blend_factor: Factor to blend the two waveforms.
|
|
damping_factor: Damping factor applied to the waveform.
|
|
enable_damping: Boolean to toggle damping.
|
|
min_sigma: Minimum sigma value for the waveform.
|
|
apply_fourier: Boolean to toggle Fourier transformation.
|
|
horizontal_length: Proportion of each horizontal segment length in the stepped waveform.
|
|
enable_unidirectional: Boolean to toggle uni-directional transformation.
|
|
|
|
|
|
FourierFilterNode
|
|
The FourierFilterNode processes an input sigma sequence using a Fourier transform, applies a frequency filter,
|
|
and optionally performs an inverse Fourier transform.
|
|
It supports various filter types, including lowpass, highpass, bandpass, and bandstop.
|
|
|
|
Parameters:
|
|
|
|
sigmas: Input sigma sequence.
|
|
filter_type: Type of frequency filter to apply
|
|
(lowpass, highpass, bandpass, bandstop).
|
|
cutoff_frequency: Cutoff frequency for the filter.
|
|
apply_inverse_fourier: Boolean to toggle inverse Fourier transform.
|
|
|
|
|
|
AttenuatorNode
|
|
The AttenuatorNode adjusts the amplitude of a sigma sequence by applying an attenuation factor.
|
|
This node is useful for fine-tuning the output of waveform generators or after applying a Fourier filter.
|
|
|
|
Parameters:
|
|
sigmas: Input sigma sequence.
|
|
attenuation_factor: Factor by which to attenuate the sigma sequence.
|
|
|
|
PhaseLockedLoopNode
|
|
The PhaseLockedLoopNode locks the phase of an input sigma sequence to a reference sigma sequence.
|
|
This node is useful for synchronization tasks where the phase of an output signal needs to match a reference signal.
|
|
|
|
Parameters:
|
|
|
|
input_sigmas: Input sigma sequence.
|
|
reference_sigmas: Reference sigma sequence to lock the phase to.
|
|
lock_factor: Factor by which to lock the phase.
|
|
frequency_range: Frequency range for the phase-locked loop.
