# EmptyLatentAudio - ComfyUI Built-in Node Documentation

> Empty Latent Audio creates an empty latent tensor for audio processing.

Empty Latent Audio creates an empty latent tensor for audio processing. It generates a blank audio latent representation with a specified duration and batch size, which can be used as a starting point for audio generation or processing workflows. The node automatically calculates the appropriate latent dimensions based on the audio duration and sample rate.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `seconds` | The duration of the audio in seconds (default: 47.6) | 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 |
| - | - | - |
| `LATENT` | Returns an empty latent tensor for audio processing with the specified duration and batch size. The tensor has a shape of \[batch\_size, 64, length], where length is calculated from the audio duration and sample rate. The output also includes metadata indicating the type is "audio" and a temporal downscale ratio of 2048. | LATENT |
