# PreviewAudio - ComfyUI Built-in Node Documentation

> The Preview Audio node lets you listen to audio directly in the ComfyUI interface without saving it to the output directory.

The Preview Audio node lets you listen to audio directly in the ComfyUI interface without saving it to the output directory. It takes audio data as input, verifies it is present, and passes it through while showing a temporary audio player so you can hear the result.

## Inputs

| Parameter | Description                                                                                                                              | Data Type | Required | Range |

| `audio`   | The audio data to preview. The node raises a ValueError if the input is None, which can happen when the source video has no audio track. | AUDIO     | Yes      | -     |

## Outputs

| Output Name | Description                                                                | Data Type |
