ComfyUI Node: Save Audio

Save Audio:

SaltSaveAudio is a node designed to facilitate the saving of audio data into various file formats. This node is particularly useful for AI artists who need to export their generated audio content into standard audio file formats such as WAV, MP3, or FLAC. By providing a straightforward method to save audio files with customizable filename prefixes and format options, SaltSaveAudio streamlines the process of managing and organizing audio outputs. The node ensures that each saved file has a unique name to prevent overwriting, making it easier to handle multiple audio files efficiently. This functionality is essential for maintaining a well-organized workflow, especially when dealing with numerous audio outputs.

Save Audio Input Parameters:

audio

This parameter represents the audio data that you want to save. It is required and should be in a format that can be processed by the node. The audio data is typically provided in a binary format that the node can convert and save into the specified file format.

filename_prefix

This parameter allows you to specify a prefix for the filename of the saved audio file. The default value is "audio_sfx". This prefix helps in organizing and identifying the saved audio files, especially when dealing with multiple files. For example, if the prefix is set to "my_audio", the saved files will be named "my_audio_0000.wav", "my_audio_0001.wav", and so on.

format

This parameter specifies the format in which the audio file will be saved. The available options are "wav", "mp3", and "flac". The default format is "wav". Choosing the appropriate format depends on your specific needs, such as file size, quality, and compatibility with other software or devices. For instance, WAV files are uncompressed and offer high quality, while MP3 files are compressed and take up less space.

Save Audio Output Parameters:

None

SaltSaveAudio does not produce any direct output parameters. Its primary function is to save the provided audio data to a file in the specified format. The success of this operation is typically indicated through logging messages rather than output parameters.

Save Audio Usage Tips:

• Ensure that the audio data provided to the node is in a compatible format to avoid errors during the saving process.
• Use descriptive and unique filename prefixes to easily identify and manage your saved audio files.
• Choose the appropriate audio format based on your requirements for quality and file size. For high-quality audio, use WAV; for smaller file sizes, consider MP3 or FLAC.

Save Audio Common Errors and Solutions:

Unsupported format: {format}. Defaulting to WAV.

• Explanation: This error occurs when an unsupported audio format is specified.
• Solution: Ensure that the format parameter is set to one of the supported formats: "wav", "mp3", or "flac". If you encounter this error, the node will automatically default to saving the file in WAV format.

File already exists: {filename}

• Explanation: This error occurs when the node attempts to save a file with a name that already exists in the output directory.
• Solution: The node automatically increments the filename to ensure uniqueness. No action is required from you, but you can check the output directory to verify the saved files.

Error saving audio file: {error_message}

• Explanation: This error occurs when there is an issue during the audio file saving process.
• Solution: Check the provided audio data and ensure it is in a compatible format. Verify that the output directory is accessible and has write permissions. If the problem persists, review the error message for more details and consult the documentation or support resources for further assistance.
