ComfyUI Node: Audio Invert Phase

Audio Invert Phase:

The pymss_audio_invert_phase node is designed to invert the phase of an audio signal, effectively flipping the waveform vertically. This operation is particularly useful in audio processing for tasks such as phase cancellation, where two audio signals are combined to reduce or eliminate certain frequencies. By inverting the phase, you can achieve creative effects or correct phase issues in multi-track recordings. This node is a valuable tool for audio engineers and AI artists who want to manipulate audio signals to achieve specific sound characteristics or resolve phase-related problems.

Audio Invert Phase Input Parameters:

a

The a parameter represents the audio input that you want to process. It is a required parameter and must be provided in the form of an audio object, which includes the waveform data. The waveform is expected to be in a specific format, typically a tensor with dimensions representing batch, channels, and samples. This parameter is crucial as it determines the audio signal that will undergo phase inversion. There are no minimum, maximum, or default values specified for this parameter, as it depends on the audio data you provide.

Audio Invert Phase Output Parameters:

-a

The -a output parameter is the result of the phase inversion process. It returns the audio object with its waveform inverted. This means that every sample in the waveform has been multiplied by -1, effectively flipping the waveform vertically. The output retains the original audio's sample rate and other metadata, ensuring that the inverted audio can be used seamlessly in further processing or playback. This output is essential for applications where phase manipulation is required to achieve desired audio effects or corrections.

Audio Invert Phase Usage Tips:

• Ensure that the input audio is correctly formatted as a tensor with dimensions for batch, channels, and samples to avoid errors during processing.
• Use phase inversion creatively to achieve unique audio effects or to address phase cancellation issues in multi-track recordings.

Audio Invert Phase Common Errors and Solutions:

audio input a is required.

• Explanation: This error occurs when the input audio parameter a is not provided to the node.
• Solution: Ensure that you supply a valid audio object as input to the node. Check that the audio data is correctly formatted and passed to the node.

Expected ComfyUI AUDIO waveform [batch, channels, samples], got shape <shape>

• Explanation: This error indicates that the input audio waveform does not have the expected dimensions.
• Solution: Verify that the input audio is a tensor with the correct dimensions: batch, channels, and samples. Adjust the input data to match this format before passing it to the node.
