ComfyUI Node: Load And Combined Audio

Load And Combined Audio:

The LoadAndCombinedAudio_ node is designed to facilitate the loading and combination of audio files within your AI art projects. This node allows you to input multiple audio files, specify the start time and duration for each, and then combine them into a single audio output. This functionality is particularly useful for creating complex audio compositions or soundscapes by merging different audio segments seamlessly. The node ensures that the audio files are processed efficiently and provides a straightforward way to manage and manipulate audio data within your creative workflows.

Load And Combined Audio Input Parameters:

audios

This parameter accepts audio files in base64 format. It is essential for loading the audio data that you want to combine. The input should be a valid base64 encoded string representing the audio file.

start_time

This parameter specifies the start time in seconds for the audio segment you want to use. It allows you to define the exact point in the audio file where the segment should begin. The default value is 0, with a minimum value of 0 and a maximum value of 10,000,000, allowing for precise control over the audio segment's starting point.

duration

This parameter defines the duration in seconds for the audio segment. It determines how long the audio segment should be from the specified start time. The default value is 10 seconds, with a minimum value of -1 (indicating no cropping) and a maximum value of 10,000,000. This flexibility enables you to extract and use specific portions of the audio file as needed.

Load And Combined Audio Output Parameters:

audio_file_path

This output parameter provides the file path of the combined audio file. It is a string that indicates where the resulting audio file is saved, allowing you to easily locate and use the combined audio in your projects.

audio

This output parameter contains the combined audio data. It is a dictionary that includes the waveform and sample rate of the audio, providing you with the necessary information to further process or analyze the audio data within your workflows.

Load And Combined Audio Usage Tips:

• Ensure that your input audio files are correctly encoded in base64 format to avoid loading issues.
• Use the start_time and duration parameters to precisely control the segments of audio you want to combine, allowing for more creative flexibility.
• If you do not want to crop the audio, set the duration parameter to -1 to use the entire audio file from the specified start time.

Load And Combined Audio Common Errors and Solutions:

Invalid audio file: <audio>

• Explanation: This error occurs when the specified audio file cannot be found or is not correctly encoded in base64 format.
• Solution: Verify that the audio file exists and is correctly encoded in base64 format. Ensure the file path or base64 string is accurate.

Audio processing failed

• Explanation: This error may occur if there is an issue during the audio loading or combining process.
• Solution: Check the input parameters for any inconsistencies or errors. Ensure that the audio files are in supported formats and that the start_time and duration values are within valid ranges.
