ComfyUI Node: (deforum) Amplitude Time Smoothing

(deforum) Amplitude Time Smoothing:

The TimeSmoothing node is designed to smooth out amplitude data over time, providing a more consistent and less erratic representation of audio signals. This is particularly useful in audio processing tasks where you want to reduce noise or fluctuations in amplitude, making the data easier to analyze or visualize. By applying a smoothing filter, this node helps in achieving a cleaner and more stable amplitude signal, which can be beneficial for various audio analysis and synchronization tasks.

(deforum) Amplitude Time Smoothing Input Parameters:

amplitude

The amplitude parameter represents the raw amplitude data of the audio signal that you want to smooth. This data is typically a sequence of numerical values that indicate the strength or intensity of the audio signal at different points in time. The quality of the input amplitude data directly affects the effectiveness of the smoothing process.

window_size

The window_size parameter determines the size of the smoothing window, which is the number of data points used to calculate the average amplitude at each point in time. A larger window size results in a smoother signal but may also reduce the responsiveness to rapid changes in amplitude. Conversely, a smaller window size preserves more detail but may not smooth out fluctuations as effectively. The default value is 5, with a minimum value of 1.

(deforum) Amplitude Time Smoothing Output Parameters:

smoothed_amplitude

The smoothed_amplitude parameter is the output of the node, representing the amplitude data after the smoothing process has been applied. This smoothed amplitude data is less noisy and more stable, making it easier to work with for further audio analysis or visualization tasks. The output is a sequence of numerical values that correspond to the smoothed amplitude at each point in time.

(deforum) Amplitude Time Smoothing Usage Tips:

• To achieve a smoother signal, increase the window_size parameter. This is useful when dealing with noisy amplitude data.
• If you need to preserve more detail and responsiveness in the amplitude data, use a smaller window_size.
• Experiment with different window_size values to find the optimal balance between smoothness and detail for your specific audio processing task.

(deforum) Amplitude Time Smoothing Common Errors and Solutions:

ValueError: window_size must be at least 1

• Explanation: This error occurs when the window_size parameter is set to a value less than 1. - Solution: Ensure that the window_size parameter is set to a value of 1 or greater.

TypeError: amplitude data must be a numerical sequence

• Explanation: This error occurs when the amplitude parameter is not provided as a numerical sequence.
• Solution: Verify that the amplitude parameter is a sequence of numerical values representing the audio signal's amplitude.

ValueError: amplitude data cannot be empty

• Explanation: This error occurs when the amplitude parameter is an empty sequence.
• Solution: Ensure that the amplitude parameter contains valid amplitude data before passing it to the node.
