ComfyUI Node: Clip Amplitude

Clip Amplitude:

The ClipAmplitude node is designed to manage and constrain the amplitude values of an audio signal within specified limits. This node is particularly useful in audio processing tasks where you need to ensure that the amplitude of the signal does not exceed a certain maximum value or fall below a certain minimum value. By clipping the amplitude, you can prevent distortion and maintain the integrity of the audio signal. The primary function of this node is to take an input amplitude and adjust it so that it stays within the defined range, providing a controlled and predictable output.

Clip Amplitude Input Parameters:

amplitude

The amplitude parameter represents the input amplitude values that you want to clip. This parameter is essential as it provides the raw amplitude data that will be processed by the node.

max_amplitude

The max_amplitude parameter sets the upper limit for the amplitude values. Any input amplitude value that exceeds this limit will be clipped to this maximum value. This parameter helps in preventing the amplitude from going too high, which can cause distortion. The default value is 1000, with a minimum value of 0 and a step size of 1.

min_amplitude

The min_amplitude parameter sets the lower limit for the amplitude values. Any input amplitude value that falls below this limit will be clipped to this minimum value. This parameter ensures that the amplitude does not drop too low, which can be useful in maintaining a certain level of signal strength. The default value is 0, with a minimum value of 0 and a step size of 1.

Clip Amplitude Output Parameters:

amplitude

The amplitude output parameter provides the clipped amplitude values. This output represents the processed amplitude data that has been constrained within the specified max_amplitude and min_amplitude limits. The clipped amplitude ensures that the signal remains within the desired range, preventing distortion and maintaining signal integrity.

Clip Amplitude Usage Tips:

• Ensure that the max_amplitude is set to a value that prevents distortion in your audio signal while maintaining the desired loudness.
• Use the min_amplitude parameter to avoid having very low amplitude values that might be inaudible or cause issues in subsequent processing stages.
• Experiment with different max_amplitude and min_amplitude settings to find the optimal range for your specific audio processing task.

Clip Amplitude Common Errors and Solutions:

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, which is not logically valid.
• Solution: Ensure that the min_amplitude value is always less than or equal to the max_amplitude value. Adjust the parameters accordingly to resolve this error.
