ComfyUI Node: Load Audio from Batch

Load Audio from Batch:

The TT-LoadBatch node is designed to facilitate the loading and processing of audio files in batch mode, making it an essential tool for handling multiple audio files efficiently. This node is particularly useful for AI artists and developers working with audio data, as it streamlines the process of loading audio files from a specified directory, applying filters based on file extensions, and optionally using regular expressions to include or exclude certain files. By automating the batch loading of audio files, TT-LoadBatch significantly reduces the manual effort required to manage large audio datasets, allowing you to focus on creative and analytical tasks. The node ensures that only valid audio files are processed, enhancing the reliability and accuracy of subsequent audio processing tasks.

Load Audio from Batch Input Parameters:

base_folder

The base_folder parameter specifies the root directory from which the audio files will be loaded. It can take values such as 'input' or 'root', determining whether the files are loaded from a predefined input directory or the root directory. This parameter is crucial as it sets the starting point for the file search, impacting which files are available for processing.

path

The path parameter defines the specific subdirectory within the base_folder where the audio files are located. This allows for precise targeting of the desired files, ensuring that only files within the specified path are considered for loading. It is important for organizing and accessing files in a structured manner.

regex_match

The regex_match parameter allows you to specify a regular expression pattern to filter files that should be included in the batch. This is useful for selecting files that match certain naming conventions or patterns, providing flexibility in file selection based on specific criteria.

regex_exclude

The regex_exclude parameter is used to define a regular expression pattern for excluding files from the batch. This helps in removing unwanted files that may otherwise be included, ensuring that only relevant files are processed. It is particularly useful for excluding files that do not meet certain criteria.

Load Audio from Batch Output Parameters:

audio_batch

The audio_batch output is a list of dictionaries, each containing information about an audio file, such as its filename and file path. This output is essential as it provides a structured representation of the loaded audio files, ready for further processing or analysis.

batch_size

The batch_size output indicates the number of audio files successfully loaded into the batch. This is important for understanding the scale of the batch and for planning subsequent processing steps that depend on the number of files.

file_list

The file_list output is a list of filenames that were included in the batch. This output is useful for verification and logging purposes, allowing you to confirm which files were processed and to maintain a record of the batch contents.

Load Audio from Batch Usage Tips:

• Ensure that the base_folder and path parameters are correctly set to avoid loading files from unintended directories.
• Use regex_match and regex_exclude to fine-tune the selection of files, especially when dealing with large datasets with mixed file types.
• Regularly verify the file_list output to ensure that the correct files are being processed, which can help in troubleshooting and maintaining data integrity.

Load Audio from Batch Common Errors and Solutions:

Path <path_dir> does not exist

• Explanation: This error occurs when the specified directory path does not exist.
• Solution: Verify that the base_folder and path parameters are correctly set and that the directory exists on the file system.

Path <path_dir> is not a directory

• Explanation: This error indicates that the specified path is not a directory.
• Solution: Ensure that the path parameter points to a valid directory and not a file.

No files found matching the criteria

• Explanation: This error occurs when no files match the specified regex_match or regex_exclude criteria.
• Solution: Review the regular expressions used and adjust them to match the desired files. Check the directory for the presence of files that meet the criteria.
