ComfyUI Node: Normalize Amplitude

Normalize Amplitude:

The NormalizeAmplitude node is designed to adjust the amplitude of an audio signal to a normalized scale, making it easier to work with and analyze. This node ensures that the amplitude values are scaled between 0 and 1, which can be particularly useful for subsequent processing steps that require a consistent amplitude range. Additionally, it offers an option to invert the normalized values, providing flexibility in how the normalized data is utilized. By normalizing the amplitude, you can achieve a more uniform representation of the audio signal, which can enhance the performance of various audio processing tasks.

Normalize Amplitude Input Parameters:

amplitude

This parameter represents the raw amplitude values of the audio signal that you want to normalize. The function of this parameter is to provide the input data that will be scaled to a normalized range. The impact of this parameter on the node's execution is significant, as it directly influences the resulting normalized amplitude values.

invert_normalized

This optional boolean parameter determines whether the normalized amplitude values should be inverted. If set to True, the normalized values will be subtracted from 1, effectively inverting the amplitude. The default value is False. This parameter allows for additional flexibility in how the normalized data is represented, which can be useful for specific audio processing tasks.

Normalize Amplitude Output Parameters:

normalized_amp

This output parameter represents the normalized amplitude values of the input audio signal. The function of this parameter is to provide a consistent amplitude range between 0 and 1, which can be used for further audio processing or analysis. The importance of this output lies in its ability to standardize the amplitude values, making it easier to compare and manipulate audio signals.

Normalize Amplitude Usage Tips:

• To achieve a standard normalized amplitude range, ensure that the invert_normalized parameter is set to False.
• If you need to invert the normalized amplitude values for specific processing tasks, set the invert_normalized parameter to True.
• Use the normalized amplitude values as input for other nodes that require a consistent amplitude range for optimal performance.

Normalize Amplitude Common Errors and Solutions:

ValueError: "min_amplitude 'X' cannot be higher than max_amplitude 'Y'"

• Explanation: This error occurs when the minimum amplitude value is set higher than the maximum amplitude value.
• Solution: Ensure that the min_amplitude parameter is less than or equal to the max_amplitude parameter.

TypeError: "unsupported operand type(s) for /: 'NoneType' and 'float'"

• Explanation: This error occurs when the input amplitude values are not properly provided or are of an incorrect type.
• Solution: Verify that the amplitude parameter is correctly set with valid amplitude values before executing the node.
