# VEED Clean Audio API

> Réducteur de bruit vocal qui nettoie les enregistrements bruyants ou la piste audio d'une vidéo et normalise le volume

Supprime le bruit de fond des enregistrements vocaux. `audio_url` accepte tout format audio ou vidéo que ffmpeg peut décoder. `strength` (0-1) définit le niveau de suppression appliqué sous la parole, et `target_lufs` (-40 à -8) définit le volume de sortie, ou peut être omis. La sortie est en mono 48 kHz 16 bits, au format flac ou wav, avec la durée de l'entrée.

- Model id: `veed/clean-audio`

- Category: Audio
- Output: audio
- Price per minute of your input audio: $0.0125 / minute of input audio (cheapest run $0.013 (13 API credits))
- Run: `POST https://api.doitong.com/v1/run/veed/clean-audio`
- Quote: `POST https://api.doitong.com/v1/quote/veed/clean-audio`
- Docs page: https://doitong.com/fr/developers/models/veed/clean-audio

## Pricing

Price: **$0.0125 / minute of input audio**. Price per minute of your input audio: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $0.013 = 13 API credits (1 min input audio × $0.0125).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/veed/clean-audio` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `audio_url` | `audio` | string (audio URL) | yes |  |  | Enregistrement fourni pour nettoyage via une URL publique ou une URI de données, acceptant tout audio ou toute vidéo décodable par ffmpeg, notamment wav, ogg, mp3, webm, m4a, mov, aac et mp4. Pour une vidéo, le traitement utilise la piste audio ; appelez /video pour recevoir la vidéo avec l'audio nettoyé, et les enregistrements multicanaux sont réduits en mono. La durée maximale est de 30 minutes, avec une limite de taille de 512 MB. |
| `strength` |  | number | no | `0.874` | 0 – 1 | Intensité de suppression du bruit de fond vocal : des valeurs plus faibles conservent davantage l'ambiance de la pièce sous la voix, mais les pauses entre les mots sont entièrement nettoyées dans tous les cas. Le niveau minimal du son d'origine restant est 1 moins l'intensité ; la valeur par défaut de 0.874 correspond au paramètre validé de -18 dB. |
| `target_lufs` |  | number \| null | no | `-19` | -40 – -8 | Cible de niveau sonore intégré selon ITU-R BS.1770 ; fournir null via l'API contourne la normalisation et conserve le niveau source. Sinon, la valeur par défaut est -19 LUFS, comme dans l'éditeur VEED, et le plafond de true peak est -1.1 dBTP. |
| `output_format` |  | enum (string) | no | `flac` | `flac`, `wav` | Format de conteneur audio : FLAC conserve une qualité sans perte pour une taille de fichier environ deux fois moindre que WAV. La sortie comporte un canal à 48 kHz avec des échantillons de 16 bits. |

File parameters (`audio`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

A fuller example:

```json
{
  "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/veed/clean-audio?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/veed/clean-audio?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/veed/clean-audio", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "veed/clean-audio",
      "input": {
        "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
