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

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

## Outputs

| Output Name | Description | Data Type |
| --- | --- | --- |
| `Latent` | An empty latent audio tensor with the structure (batch_size, z_channels, num_audio_latents, audio_freq) configured to match the input Audio VAE. The output also includes a `type` field set to "audio". | LATENT |
