# VeedCleanVideoAudioNode - ComfyUI Built-in Node Documentation

> Remove background noise from the speech in a video with VEED.

Remove background noise from the speech in a video with VEED. Only the soundtrack changes: it is replaced with the cleaned 48 kHz mono speech while the picture, resolution and frame rate stay as they are. It is built for speech in any language, and music and sound effects are removed rather than preserved.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `video` | Video with a speech soundtrack, shorter than 30 minutes. The video must have an audio track. | VIDEO | Yes | Up to 1799 seconds |
| `strength` | How much noise is removed under speech. Lower keeps more room tone behind the voice; pauses between words are always fully cleaned, and values above the default change little. (default: 0.874) | FLOAT | Yes | 0.0 to 1.0 (step 0.001) |
| `loudness` | Whether to normalize the speech loudness. `"normalize"` sets it to `target_lufs`; `"keep input level"` leaves the level as it is. Selecting an option reveals its parameters. (default: `"normalize"`) | DYNAMIC\_COMBO | Yes | `"normalize"` `"keep input level"` |
| `target_lufs` | Integrated loudness of the cleaned speech in LUFS. Peaks are capped at -1.1 dBTP, so loud targets stop early (about -15 LUFS for typical speech). Available when `loudness` is `"normalize"` (default: -19.0). | FLOAT | Yes | -40.0 to -8.0 (step 0.1) |

The node stops with an error when the clip is longer than 1799 seconds, and when the video has no audio track.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `VIDEO` | The input video with its soundtrack replaced by the cleaned speech. | VIDEO |
