# EmptyYuE2LatentAudio - ComfyUI Built-in Node Documentation

> This node creates an empty audio latent for YuE2, sized to a chosen duration and batch count.

This node creates an empty audio latent for YuE2, sized to a chosen duration and batch count. It produces silent placeholder audio data that later nodes can fill in during audio generation.

## Inputs

| Parameter    | Description                                                                                                                                              | Data Type | Required | Range                      |
| ------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | -------------------------- |
| `seconds`    | Length of the audio latent to create, in seconds (default: 120.0). The number of latent frames is calculated from this value, with a minimum of 1 frame. | FLOAT     | Yes      | 0.04 to 1000.0 (step 0.04) |
| `batch_size` | Number of audio latents to create in one batch (default: 1).                                                                                             | INT       | Yes      | 1 to 4096                  |

## Outputs

| Output Name | Description                                                                                                                                                                               | Data Type |
| ----------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `LATENT`    | An empty audio latent containing a tensor of zeros, sized by `batch_size` and the frame count derived from `seconds`. It is tagged as audio type with a temporal downscale ratio of 1920. | LATENT    |
