# EmptyMiniMaxMusic3LatentAudio - ComfyUI Built-in Node Documentation

> This node creates an empty (zero-filled) latent audio tensor for the MiniMax Music3 model.

This node creates an empty (zero-filled) latent audio tensor for the MiniMax Music3 model. It converts the requested duration in seconds into the corresponding audio frames and produces a blank latent of the correct size, ready to be used as the starting point for music generation.

## Inputs

| Parameter    | Description                                                                                                                                                | Data Type | Required | Range                                                                              |
| ------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ---------------------------------------------------------------------------------- |
| `seconds`    | The duration of the audio latent in seconds (default: 120.0). The value is converted to audio frames and clamped to the model's supported duration limits. | FLOAT     | Yes      | 0.04 to model maximum (MAX\_AUDIO\_FRAMES / AUDIO\_FRAMES\_PER\_SECOND), step 0.04 |
| `batch_size` | The number of audio latents to generate in one batch (default: 1).                                                                                         | INT       | Yes      | 1 to 4096                                                                          |

Note: The `seconds` value is rounded to the nearest audio frame and clamped to a minimum of 1 frame and a maximum of `MAX_AUDIO_FRAMES` frames, so the actual latent length may differ slightly from the exact value entered.

## Outputs

| Output Name | Description                                                                                                                                                                  | Data Type |
| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `LATENT`    | A zero-filled audio latent tensor of shape (batch\_size, 128, latent\_length). Includes metadata that marks the sample as audio data with a temporal downscale ratio of 512. | LATENT    |
