ComfyUI Node: Pink Noise

Pink Noise:

The JDC_PinkNoise node is designed to generate pink noise, a type of noise with a frequency spectrum that falls off at higher frequencies, making it useful for various artistic and technical applications. Pink noise is often used in audio engineering, visual effects, and procedural texture generation due to its natural and aesthetically pleasing properties. This node allows you to create pink noise images with customizable parameters, enabling you to control the noise characteristics and achieve the desired visual effect. By adjusting the input parameters, you can fine-tune the noise to suit your specific needs, whether it's for creating backgrounds, textures, or other visual elements in your AI art projects.

Pink Noise Input Parameters:

width

The width parameter specifies the width of the generated noise image in pixels. It determines how wide the resulting image will be. The value should be a positive integer representing the number of pixels. Adjusting this parameter allows you to control the horizontal resolution of the noise image.

height

The height parameter specifies the height of the generated noise image in pixels. It determines how tall the resulting image will be. The value should be a positive integer representing the number of pixels. Adjusting this parameter allows you to control the vertical resolution of the noise image.

value_min

The value_min parameter sets the minimum value for the noise intensity. It controls the darkest possible value in the noise image. The value should be an integer between 0 and 255. Setting this parameter helps in defining the lower bound of the noise intensity range.

value_max

The value_max parameter sets the maximum value for the noise intensity. It controls the brightest possible value in the noise image. The value should be an integer between 0 and 255. Setting this parameter helps in defining the upper bound of the noise intensity range.

red_min

The red_min parameter sets the minimum value for the red channel in the noise image. It controls the darkest possible red value. The value should be an integer between 0 and 255. Adjusting this parameter allows you to control the lower bound of the red channel intensity.

red_max

The red_max parameter sets the maximum value for the red channel in the noise image. It controls the brightest possible red value. The value should be an integer between 0 and 255. Adjusting this parameter allows you to control the upper bound of the red channel intensity.

green_min

The green_min parameter sets the minimum value for the green channel in the noise image. It controls the darkest possible green value. The value should be an integer between 0 and 255. Adjusting this parameter allows you to control the lower bound of the green channel intensity.

green_max

The green_max parameter sets the maximum value for the green channel in the noise image. It controls the brightest possible green value. The value should be an integer between 0 and 255. Adjusting this parameter allows you to control the upper bound of the green channel intensity.

blue_min

The blue_min parameter sets the minimum value for the blue channel in the noise image. It controls the darkest possible blue value. The value should be an integer between 0 and 255. Adjusting this parameter allows you to control the lower bound of the blue channel intensity.

blue_max

The blue_max parameter sets the maximum value for the blue channel in the noise image. It controls the brightest possible blue value. The value should be an integer between 0 and 255. Adjusting this parameter allows you to control the upper bound of the blue channel intensity.

seed

The seed parameter is used to initialize the random number generator for noise generation. It ensures that the same noise pattern can be reproduced if the same seed value is used. The value should be an integer. Changing the seed value will result in a different noise pattern, providing variability in the generated noise images.

Pink Noise Output Parameters:

noise_image

The noise_image parameter is the output of the JDC_PinkNoise node. It represents the generated pink noise image based on the specified input parameters. The output is an image with the specified width and height, containing the pink noise pattern. This image can be used directly in your AI art projects or further processed to achieve the desired visual effects.

Pink Noise Usage Tips:

• Experiment with different seed values to generate a variety of pink noise patterns and find the one that best suits your project.
• Adjust the value_min and value_max parameters to control the overall contrast of the noise image, making it either more subtle or more pronounced.
• Use the red_min, red_max, green_min, green_max, blue_min, and blue_max parameters to create colored noise with specific color characteristics, adding a unique touch to your visual elements.
• Combine the pink noise image with other textures or images to create complex and interesting backgrounds or overlays.

Pink Noise Common Errors and Solutions:

"Invalid width or height value"

• Explanation: The width or height parameter is set to a non-positive integer.
• Solution: Ensure that both the width and height parameters are positive integers representing the desired dimensions of the noise image.

"Value out of range for value_min or value_max"

• Explanation: The value_min or value_max parameter is set outside the valid range of 0 to 255. - Solution: Adjust the value_min and value_max parameters to be within the range of 0 to 255.

"Value out of range for red_min, red_max, green_min, green_max, blue_min, or blue_max"

• Explanation: One of the color channel parameters is set outside the valid range of 0 to 255. - Solution: Ensure that all color channel parameters (red_min, red_max, green_min, green_max, blue_min, blue_max) are within the range of 0 to 255.

"Seed value is not an integer"

• Explanation: The seed parameter is set to a non-integer value.
• Solution: Make sure the seed parameter is an integer to ensure proper initialization of the random number generator.
