# Sam Audio · Span Separate API

> Ka wehea he oro mai i te ororongo mā ngā awhe wā ka hoatu e koe, me tētahi tohu kuputuhi kōwhiringa

Kāore e whakawhirinaki ki te kuputuhi anake; tukuna ngā `spans` e tohu ana i te wā ka puta te oro whāia i roto i `audio_url`. He kōwhiringa te `prompt`, engari ka āwhina ki te tautuhi i te momo oro. Ka taea e `trim_to_span` te tapahi i te putanga ki te awhe span, ā, mā `use_sound_activity_ranking` e taea ai te whakaraupapa anō me te kore tohutohu. Ka whakahoki ororongo `target` me `residual` i te wav, i te mp3 rānei.

- Model id: `sam-audio/span-separate`
- Made by: Meta
- Category: Audio
- Output: json
- Price per 30 seconds of your input audio: from $0.05 / 30 seconds of input audio (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.ru/v1/run/sam-audio/span-separate`
- Quote: `POST https://api.doitong.ru/v1/quote/sam-audio/span-separate`
- Docs page: https://doitong.com/mi/developers/models/sam-audio/span-separate

## Pricing

Price: **from $0.05 / 30 seconds of input audio** (the lowest tier; the quote prices your exact input). Price per 30 seconds 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 $0.05 = 50 API credits (1 × 30 s input audio × $0.05).

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/sam-audio/span-separate` 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 |

| `spans[].include` |  | boolean | no | `true` |  | Te whakauru i ngā oro kei roto i te wāhanga: ka whakaurua e True, ka whakakorehia e False. |
| `reranking_candidates` |  | integer | no | `1` | 1 – 7 | Te maha o ngā kaitono, ka whakamahia me te tohutohu kuputuhi anake: ka whakaputaina, ka whakaraupapatia taua maha o ngā kaitono. Ka waiho tēnei tautuhinga ki te wehewehenga wāhanga anake. |
| `acceleration` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `quality` | Taumata whakatere i whakamahia mō te tukatuka. |
| `max_chunk_duration` |  | number | no | `60` | 10 – 60 | Te rohe ororongo mō ia tukunga, hei hēkona; ki tua atu, ka whakamahi te tukatuka i ngā wāhanga inaki ka hanumihia. |
| `chunk_overlap` |  | number | no | `5` | 0 – 30 | Te roa o te inaki i waenga i ngā wāhanga, hei hēkona, mō te hanumi whakawhiti. |
| `use_sound_activity_ranking` |  | boolean | no | `false` |  | Kōwhiringa whakaraupapa ngohe oro me nui ake te reranking_candidates i te 1, kia whaihua ai te whakaraupapa anō mō te wehewehenga wāhanga anake, kāore he tohutohu kuputuhi. Ka whakatauria ngā kaitono e te tata o te hāngaitanga o ō rātou rohe kore-puku kua kitea ki ngā wāhanga kua tukuna. |
| `trim_to_span` |  | boolean | no | `false` |  | Kōwhiringa roa putanga i waenga i te wāhanga kua tohua me te ororongo katoa. Mā te whakahohe ka poroa ki te awhe wā o te wāhanga; mā False ka pupuri i te roa katoa, ka wehe i te oro whāia puta noa. |
| `output_format` |  | enum (string) | no | `wav` | `wav`, `mp3` | Hōputu mō te ororongo kua whakaputaina. |

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",
  "spans": [
    {
      "end": 10,
      "include": true,
      "start": 6
    }
  ]
}
```

A fuller example:

```json
{
  "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
  "spans": [
    {
      "end": 10,
      "include": true,
      "start": 6
    }
  ]
}
```

## 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/sam-audio/span-separate?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",
    "spans": [
      {
        "end": 10,
        "include": true,
        "start": 6
      }
    ]
  }'

# 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

### 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": "sam-audio/span-separate",
      "input": {
        "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
        "spans": [
          {
            "end": 10,
            "include": true,
            "start": 6
          }
        ]
      },
      "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.
