# ReferenceTimbreAudio - ComfyUI Built-in Node Documentation

> This node sets the reference audio for the "ace step 1.5" process.

This node sets the reference audio for the "ace step 1.5" process. It takes a conditioning input and optionally a latent representation of audio, then attaches that latent data to the conditioning so later nodes can use it as reference audio timbre latents. This node is marked as experimental.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `conditioning` | The conditioning data to which the reference audio information will be attached. | CONDITIONING | Yes | |
| `latent` | An optional latent representation of the reference audio (default: None). When provided, its samples are appended to the conditioning as reference audio timbre latents. | LATENT | No | |

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `conditioning` | The modified conditioning data, now containing the reference audio timbre latents if the optional `latent` input was provided. | CONDITIONING |
