# SaveAudio - ComfyUI Built-in Node Documentation

> This node saves audio data to a file in FLAC format.

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.

## Outputs

| Output Name | Description                                                                           | Data Type |
| ----------- | ------------------------------------------------------------------------------------- | --------- |
| `audio`     | The audio data that was provided to the input, passed through after the file is saved | AUDIO     |
