SaveAudio - ComfyUI Built-in Node Documentation - ComfyUI

This node saves audio data to a file in FLAC format. It takes an audio input and writes it to the output directory using the specified filename prefix. This node is deprecated and should be replaced with the current Save Audio node.

Inputs

Parameter	Description	Data Type	Required	Range
`audio`	The audio data to be saved	AUDIO	Yes	-
`filename_prefix`	The prefix for the output filename (default: “audio/ComfyUI”)	STRING	No	-

Note: The prompt and extra_pnginfo parameters are hidden and automatically handled by the system. If the audio input receives no data (for example, when the source video has no audio track), the node raises an error and no file is saved.
