# VEED Clean Audio API

> Sprachentrauscher, der verrauschte Aufnahmen oder die Audiospur eines Videos bereinigt und die Lautheit normalisiert

Entfernt Hintergrundgeräusche aus Sprachaufnahmen. `audio_url` akzeptiert jedes Audio- oder Videoformat, das ffmpeg dekodieren kann. `strength` (0-1) legt fest, wie stark die Unterdrückung während der Sprache angewendet wird, und `target_lufs` (-40 bis -8) bestimmt die Ausgabelautheit oder kann weggelassen werden. Die Ausgabe ist 48 kHz mono 16-Bit als flac oder wav und hat die Dauer der Eingabe.

- Model id: `veed/clean-audio`
- Made by: VEED
- 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.ru/v1/run/veed/clean-audio`
- Quote: `POST https://api.doitong.ru/v1/quote/veed/clean-audio`
- Docs page: https://doitong.com/de/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.ru/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 |  |  | Aufnahme zur Bereinigung über eine öffentliche URL oder Data-URI; akzeptiert alle von ffmpeg dekodierbaren Audio- oder Videoformate, einschließlich wav, ogg, mp3, webm, m4a, mov, aac und mp4. Bei Video wird die Audiospur verarbeitet; /video aufrufen, um das Video mit bereinigtem Audio zu erhalten. Mehrkanalaufnahmen werden auf Mono heruntergemischt. Maximale Dauer: 30 Minuten, Größenlimit: 512 MB. |
| `strength` |  | number | no | `0.874` | 0 – 1 | Stärke der Unterdrückung von Sprachhintergrundgeräuschen: Niedrigere Einstellungen bewahren mehr Raumklang unter der Stimme, Pausen zwischen Wörtern werden jedoch unabhängig davon vollständig bereinigt. Der Mindestanteil des verbleibenden Originaltons ist 1 minus strength; der Standardwert 0.874 entspricht der validierten Einstellung von -18 dB. |
| `target_lufs` |  | number \| null | no | `-19` | -40 – -8 | Zielwert der integrierten Ausgabelautheit gemäß ITU-R BS.1770; die Übergabe von null über die API umgeht die Normalisierung und bewahrt den Quellpegel. Andernfalls gilt standardmäßig -19 LUFS, entsprechend der Ausgabe des VEED-Editors; die True-Peak-Obergrenze liegt bei -1.1 dBTP. |
| `output_format` |  | enum (string) | no | `flac` | `flac`, `wav` | Auswahl des Audio-Containers: FLAC bewahrt verlustfreie Qualität bei etwa halber Dateigröße von WAV. Die Ausgabe hat einen Kanal mit 48 kHz und 16-Bit-Samples. |

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.ru/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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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.ru/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.ru/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.
