PreView Audio Description

Facilitates audio file previewing, extracts metadata, user-friendly interface for managing audio data in AI projects.

PreView Audio:

The PreViewAudio node is designed to facilitate the previewing of audio files within the ComfyUI-UVR5 framework. This node allows you to load an audio file and extract its basic metadata, such as the file name and its directory. The primary goal of this node is to provide a user-friendly interface for quickly accessing and identifying audio files, making it easier to manage and utilize audio data in your AI-driven projects. By offering a straightforward method to load and preview audio files, PreViewAudio enhances your workflow efficiency and ensures that you can easily verify the correct audio files are being used in your tasks.

PreView Audio Input Parameters:


The audio parameter is the path to the audio file you wish to preview. This parameter is essential as it specifies the exact file that the node will process. The function of this parameter is to provide the node with the location of the audio file, which it will then load and extract metadata from. The impact of this parameter on the node's execution is significant, as an incorrect or invalid path will result in the node being unable to locate and process the audio file. There are no specific minimum or maximum values for this parameter, but it must be a valid file path pointing to an audio file in a supported format (e.g., WAV, MP3, FLAC, M4A).

PreView Audio Output Parameters:


The ui output parameter provides a dictionary containing metadata about the loaded audio file. Specifically, it includes the file name and the root directory of the audio file. This output is crucial for verifying that the correct audio file has been loaded and for displaying relevant information in the user interface. The ui parameter helps you ensure that the audio file you intended to use is correctly identified and accessible, thereby preventing potential errors in subsequent processing steps.

PreView Audio Usage Tips:

  • Ensure that the audio parameter points to a valid and accessible audio file path to avoid errors during the loading process.
  • Use the ui output to verify the loaded audio file's name and directory, which can help in organizing and managing your audio data more effectively.
  • If you encounter issues with unsupported audio formats, consider converting your audio files to a common format like WAV or MP3 before using this node.

PreView Audio Common Errors and Solutions:

Invalid audio file path

  • Explanation: The specified audio parameter does not point to a valid or accessible audio file.
  • Solution: Double-check the file path to ensure it is correct and that the file exists. Verify that the file has the appropriate read permissions.

Unsupported audio format

  • Explanation: The audio file format is not supported by the node.
  • Solution: Convert the audio file to a supported format such as WAV, MP3, FLAC, or M4A before using the node.

File read error

  • Explanation: There was an issue reading the audio file, possibly due to file corruption or access permissions.
  • Solution: Ensure the audio file is not corrupted and that you have the necessary permissions to read the file. Try opening the file with a different application to verify its integrity.
