# EmptyAceStepLatentAudio - ComfyUI Built-in Node Documentation

> The Empty Ace Step 1.0 Latent Audio node creates empty latent audio samples for a chosen duration.

The Empty Ace Step 1.0 Latent Audio node creates empty latent audio samples for a chosen duration. It fills a batch of silent (all-zero) audio latents, where the length is calculated from the `seconds` input using audio processing parameters. This is typically used to initialize audio workflows that need a latent representation as a starting point.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `seconds` | The duration of the audio in seconds (default: 120.0, step: 0.1) | FLOAT | Yes | 1.0 - 1000.0 |
| `batch_size` | The number of latent images in the batch (default: 1) | INT | Yes | 1 - 4096 |

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `output` | Returns empty latent audio samples filled with zeros. The output contains a `samples` tensor and a `type` field set to "audio". | LATENT |
