# LTXVEmptyLatentAudio - ComfyUI Built-in Node Documentation

> Complete documentation for the LTXVEmptyLatentAudio node in ComfyUI. Learn its inputs, outputs, parameters and usage.

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/LTXVEmptyLatentAudio/en.md)

The LTXV Empty Latent Audio node creates a batch of empty (zero-filled) latent audio tensors. It uses the configuration from a provided Audio VAE model to determine the correct dimensions for the latent space, such as the number of channels and frequency bins. This empty latent serves as a starting point for audio generation or manipulation workflows within ComfyUI.

## Inputs

| Parameter       | Data Type | Required | Range     | Description                                                                |
| --------------- | --------- | -------- | --------- | -------------------------------------------------------------------------- |
| `frames_number` | INT       | Yes      | 1 to 1000 | Number of frames. The default value is 97.                                 |
| `frame_rate`    | INT       | Yes      | 1 to 1000 | Number of frames per second. The default value is 25.                      |
| `batch_size`    | INT       | Yes      | 1 to 4096 | The number of latent audio samples in the batch. The default value is 1.   |
| `audio_vae`     | VAE       | Yes      | N/A       | The Audio VAE model to get configuration from. This parameter is required. |

**Note:** The `audio_vae` input is mandatory. The node will raise an error if it is not provided.

## Outputs

| Output Name | Data Type | Description                                                                                                            |
| ----------- | --------- | ---------------------------------------------------------------------------------------------------------------------- |
| `Latent`    | LATENT    | An empty latent audio tensor with the structure (samples, sample\_rate, type) configured to match the input Audio VAE. |
