# PreviewAudio - ComfyUI Built-in Node Documentation

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

The Preview Audio node lets you listen to audio directly inside ComfyUI without saving it to the output directory. It receives an audio input, checks that audio data is actually present, and then plays it through a preview player in the interface while passing the same audio on as its output.

## Inputs

| Parameter | Description                                                                                                                                | Data Type | Required | Range |
| --------- | ------------------------------------------------------------------------------------------------------------------------------------------ | --------- | -------- | ----- |
| `audio`   | The audio data to preview. If this input is None, the node raises a ValueError, which can happen when the source video has no audio track. | AUDIO     | Yes      | -     |

## Outputs

| Output Name | Description                                                                                                    | Data Type |
| ----------- | -------------------------------------------------------------------------------------------------------------- | --------- |
| `audio`     | The audio data passed through unchanged from the input, so the node can be placed in the middle of a workflow. | AUDIO     |
