ComfyUI Node: Egregora ABX Judge

Egregora ABX Judge:

The ABX Judge node is designed to facilitate audio evaluation by determining the accuracy of a user's guess in an ABX test. This type of test is commonly used in audio processing to compare two audio samples, labeled as A and B, with a third sample X that is identical to either A or B. The primary goal of the ABX Judge is to assess whether the user's guess about which sample X matches (either A or B) is correct. This node is particularly useful for audio engineers and AI artists who need to evaluate the perceptual differences between audio samples, ensuring that enhancements or modifications in audio processing are perceptible and accurate. By providing a structured way to validate guesses, the ABX Judge helps in maintaining the integrity of audio evaluations and supports the development of high-quality audio processing techniques.

Egregora ABX Judge Input Parameters:

abx_meta

The abx_meta parameter is a dictionary that contains metadata about the ABX test, specifically indicating which sample (A or B) the X sample corresponds to. This metadata is crucial for the node to determine the correct answer in the ABX test. The x_is key within this dictionary holds the value 'A' or 'B', representing the correct match for the X sample. This parameter does not have a minimum or maximum value as it is a dictionary, but it must include the x_is key with a valid value.

guess

The guess parameter is a string input that represents the user's guess in the ABX test, indicating whether they believe the X sample matches sample A or B. The options for this parameter are limited to the strings "A" or "B". This input is case-insensitive, meaning the node will convert the guess to uppercase for comparison. The accuracy of the ABX test relies on this parameter, as it is used to compare against the correct answer provided in the abx_meta.

Egregora ABX Judge Output Parameters:

abx_result

The abx_result is a dictionary output that provides the results of the ABX test. It includes three key pieces of information: x_is, which reiterates the correct match for the X sample as provided in the abx_meta; guess, which reflects the user's input in uppercase; and correct, a boolean value indicating whether the user's guess was accurate. This output is essential for users to understand the outcome of their ABX test, providing clear feedback on their perceptual judgment.

Egregora ABX Judge Usage Tips:

• Ensure that the abx_meta parameter is correctly populated with the x_is key to avoid incorrect test results. This metadata is crucial for the node to function properly.
• Use the ABX Judge node in conjunction with the ABX Prepare node to streamline the process of setting up and evaluating ABX tests, ensuring consistency and accuracy in your audio evaluations.

Egregora ABX Judge Common Errors and Solutions:

Missing x_is in abx_meta

• Explanation: The abx_meta dictionary does not contain the required x_is key, which is necessary for determining the correct answer in the ABX test.
• Solution: Ensure that the abx_meta parameter includes the x_is key with a valid value of either 'A' or 'B' before executing the node.

Invalid guess value

• Explanation: The guess parameter contains a value other than "A" or "B", which are the only valid options for this input.
• Solution: Verify that the guess parameter is set to either "A" or "B", and ensure it is case-insensitive by converting it to uppercase if necessary.
