ComfyUI Node: Audio Saver @ vrch.ai

Audio Saver @ vrch.ai:

The VrchAudioSaverNode is designed to facilitate the efficient saving of audio data within a specified directory structure, making it an essential tool for managing audio files in a structured and organized manner. This node is particularly beneficial for users who need to handle multiple audio files, as it automates the process of saving each audio waveform with a unique filename, ensuring that no data is overwritten. By allowing customization of the file path and format, the node provides flexibility in how audio data is stored, which is crucial for projects that require precise file management. Additionally, the node supports preview functionality, enabling users to quickly verify the saved audio files without needing to navigate away from their current workflow. This feature enhances the user experience by providing immediate feedback on the saved content, thus streamlining the audio management process.

Audio Saver @ vrch.ai Input Parameters:

audio

The audio parameter is a dictionary containing the waveform and sample rate of the audio data to be saved. It is crucial for the node's operation as it provides the raw audio data that will be processed and stored. The waveform should be in a format compatible with the node's processing capabilities, typically a tensor with dimensions that the node can handle. The sample rate is also important as it ensures the audio is saved with the correct playback speed. There are no specific minimum or maximum values for this parameter, but the waveform must be correctly formatted for successful processing.

filename

The filename parameter specifies the base name for the saved audio files. It is important for identifying and organizing the saved files, especially when dealing with multiple audio waveforms. The node appends an index to the base filename if multiple waveforms are present, ensuring each file is uniquely named. There are no strict constraints on the filename, but it should be a valid string that can be used in file paths.

path

The path parameter defines the subdirectory within the output directory where the audio files will be saved. This allows users to organize their audio files into specific folders, which is useful for maintaining a clean and structured file system. The path should be a valid directory name and can include nested folders if needed.

extension

The extension parameter determines the file format of the saved audio files, such as wav or mp3. This is important for compatibility with different audio playback and editing software. The extension should be a valid audio file format that the node can handle, and it is typically specified in lowercase.

enable_preview

The enable_preview parameter is a boolean that, when set to true, enables the preview functionality of the node. This allows users to quickly access and listen to the saved audio files directly from the user interface, providing immediate feedback on the saved content. The default value is typically false, meaning previews are not generated unless explicitly requested.

Audio Saver @ vrch.ai Output Parameters:

ui

The ui output parameter is a dictionary that contains information about the saved audio files when the preview functionality is enabled. It includes details such as the filenames, subfolder paths, and file types, which are useful for verifying the saved content. This output is particularly valuable for users who need to quickly confirm that their audio files have been saved correctly and are accessible for further use.

Audio Saver @ vrch.ai Usage Tips:

• Ensure that the audio parameter is correctly formatted and contains valid waveform and sample rate data to avoid processing errors.
• Use descriptive filenames and organized paths to maintain a clear and structured file system, making it easier to locate and manage saved audio files.
• Enable the preview functionality to quickly verify the saved audio files without leaving the current workflow, saving time and effort.

Audio Saver @ vrch.ai Common Errors and Solutions:

Error: Unable to process the audio input.

• Explanation: This error occurs when the audio waveform is not in a compatible format or is missing required data.
• Solution: Verify that the audio parameter contains a correctly formatted waveform and a valid sample rate. Ensure that the waveform dimensions are appropriate for the node's processing capabilities.

Error: Invalid file path or filename.

• Explanation: This error arises when the specified path or filename contains invalid characters or is not a valid directory.
• Solution: Check that the path and filename parameters are valid strings that can be used in file paths. Avoid using special characters that are not allowed in file or directory names.
