ComfyUI Node: Batch Amplitude Schedule

Batch Amplitude Schedule:

The BatchAmplitudeSchedule node is designed to process and adjust the amplitude of audio signals in a batch manner, providing a structured way to handle amplitude changes over time. This node is particularly useful for AI artists who need to manipulate audio amplitude for various creative purposes, such as dynamic soundscapes or audio effects. By leveraging this node, you can automate the process of adjusting amplitude based on predefined parameters, ensuring consistent and precise control over the audio output. The main goal of this node is to facilitate the creation of complex audio schedules that can enhance the auditory experience in your projects.

Batch Amplitude Schedule Input Parameters:

amplitude

The amplitude parameter represents the audio signal's amplitude data that you want to process. This input is crucial as it forms the basis of the adjustments made by the node. The amplitude data should be provided in a format that the node can interpret and manipulate effectively.

frames_to_attack

The frames_to_attack parameter defines the number of frames over which the amplitude should rise to its peak value. This parameter controls the attack phase of the amplitude adjustment, determining how quickly the amplitude increases. A higher value results in a slower rise, while a lower value results in a quicker rise.

frames_to_hold

The frames_to_hold parameter specifies the number of frames during which the amplitude should be held at its peak value. This parameter controls the hold phase, allowing you to maintain the peak amplitude for a specified duration before any further adjustments are made.

frames_to_release

The frames_to_release parameter determines the number of frames over which the amplitude should decrease from its peak value. This parameter controls the release phase, dictating how quickly the amplitude falls. A higher value results in a slower fall, while a lower value results in a quicker fall.

rise_factor

The rise_factor parameter is a multiplier that influences the rate at which the amplitude rises during the attack phase. Adjusting this factor allows you to fine-tune the steepness of the rise, providing more control over the attack dynamics.

decay_factor

The decay_factor parameter is a multiplier that affects the rate at which the amplitude decreases during the release phase. By modifying this factor, you can control the steepness of the fall, allowing for precise adjustments to the release dynamics.

Batch Amplitude Schedule Output Parameters:

adjusted_amp

The adjusted_amp parameter represents the processed amplitude data after applying the attack, hold, and release adjustments. This output is crucial as it provides the final amplitude values that can be used in your audio projects. The adjusted amplitude data reflects the changes made based on the input parameters, ensuring a controlled and dynamic audio output.

Batch Amplitude Schedule Usage Tips:

• Experiment with different frames_to_attack, frames_to_hold, and frames_to_release values to achieve the desired amplitude dynamics for your audio project.
• Use the rise_factor and decay_factor parameters to fine-tune the steepness of the amplitude changes, allowing for more precise control over the audio effects.
• Combine this node with other amplitude-related nodes to create complex and dynamic audio schedules that enhance your creative projects.

Batch Amplitude Schedule Common Errors and Solutions:

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

• Explanation: This error occurs when the min_amplitude value is set higher than the max_amplitude value.
• Solution: Ensure that the min_amplitude value is always less than or equal to the max_amplitude value to avoid this error.

IndexError: list index out of range

• Explanation: This error may occur if the input amplitude data is not properly formatted or if the node attempts to access an index that does not exist in the data.
• Solution: Verify that the input amplitude data is correctly formatted and contains the expected number of frames. Ensure that the data length matches the expected input for the node.

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

• Explanation: This error can occur if one of the input parameters is not properly set or if there is a mismatch in data types.
• Solution: Check that all input parameters are correctly specified and that they match the expected data types. Ensure that no parameter is left unset or assigned a None value.
