ComfyUI Node: KfSinusoidalGetFrequency

KfSinusoidalGetFrequency:

The KfSinusoidalGetFrequency node is designed to extract the frequency value from a given sinusoidal curve. This node is particularly useful when you need to analyze or manipulate the frequency component of a sinusoidal waveform within your AI art projects. By providing a straightforward method to retrieve the frequency, it allows you to seamlessly integrate this information into your creative workflows, enabling more dynamic and responsive designs. The node calculates the frequency by taking the reciprocal of the curve's wavelength, ensuring accurate and reliable results.

KfSinusoidalGetFrequency Input Parameters:

curve

The curve parameter is a required input that expects a sinusoidal curve object. This parameter represents the sinusoidal waveform from which the frequency will be extracted. The curve must be of the type SINUSOIDAL_CURVE, and it is essential to provide this input to ensure the node functions correctly. The forceInput attribute is set to True, meaning that this input must be explicitly provided for the node to execute.

KfSinusoidalGetFrequency Output Parameters:

FLOAT

The output of the KfSinusoidalGetFrequency node is a single floating-point number representing the frequency of the provided sinusoidal curve. This value is derived by taking the reciprocal of the curve's wavelength, giving you a precise measure of how many cycles the waveform completes in a unit of time. This output is crucial for applications where understanding or modifying the frequency of a sinusoidal signal is necessary.

KfSinusoidalGetFrequency Usage Tips:

• Ensure that the input curve is a valid SINUSOIDAL_CURVE object to avoid execution errors.
• Use this node in conjunction with other sinusoidal nodes to create complex waveforms and animations.
• The frequency value can be used to synchronize other elements in your project, such as timing animations or modulating other parameters.

KfSinusoidalGetFrequency Common Errors and Solutions:

Invalid curve input

• Explanation: The provided curve is not of type SINUSOIDAL_CURVE.
• Solution: Ensure that the input curve is correctly generated and is of the type SINUSOIDAL_CURVE.

Division by zero

• Explanation: The wavelength of the curve is zero, leading to a division by zero error when calculating the frequency.
• Solution: Verify that the input curve has a non-zero wavelength before passing it to the node. Adjust the curve parameters if necessary to avoid a zero wavelength.
