# Sam Audio · Span Separate API

> Hutenga sauti kutoka kwenye sauti kwa kutumia vipindi vya muda unavyotoa, pamoja na dokezo la hiari la maandishi

Badala ya kutegemea maandishi pekee, unapitisha `spans` zinazoonyesha wakati sauti lengwa inapotokea kwenye `audio_url`. `prompt` ni ya hiari lakini husaidia kutambua aina ya sauti. `trim_to_span` inaweza kukata tokeo hadi kwenye kipindi cha span, na `use_sound_activity_ranking` huruhusu kupanga upya bila kidokezo. Hurejesha sauti za `target` na `residual` katika wav au mp3.

- 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/sw/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 |
|---|---|---|---|---|---|---|
| `audio_url` | `audio` | string (audio URL) | yes |  |  | URL ya faili la sauti kwa uchakataji. |
| `prompt` |  | string \| null | no |  |  | Msaada wa kutambua sauti kwa kutoa sauti kutoka kwenye sehemu. Maelezo ya maandishi ya sauti ya kutengwa yanapendekezwa, ingawa si lazima. |
| `spans` |  | array of object {start, end, include} | yes |  |  | Vipindi vya muda vilivyo na sauti lengwa ya kutengwa. |
| `spans[].start` |  | number | yes |  | ≥ 0 | Muhuri wa muda wa kuanza kwa sehemu, unaopimwa kwa sekunde. |
| `spans[].end` |  | number | yes |  | ≥ 0 | Muhuri wa muda wa mwisho wa sehemu, unaopimwa kwa sekunde. |
| `spans[].include` |  | boolean | no | `true` |  | Ujumuishaji wa sauti ndani ya sehemu: True huzijumuisha, huku False ikiziondoa. |
| `reranking_candidates` |  | integer | no | `1` | 1 – 7 | Idadi ya wagombea inayotumika tu pamoja na kidokezo cha maandishi: idadi hiyo ya wagombea huzalishwa na kupangwa. Utenganishaji wa sehemu pekee hupuuza mpangilio huu. |
| `acceleration` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `quality` | Kiwango cha kuongeza kasi kinachotumika kwenye uchakataji. |
| `max_chunk_duration` |  | number | no | `60` | 10 – 60 | Kikomo cha sauti kwa kila pasi, kinachopimwa kwa sekunde, ambacho kikizidi uchakataji hutumia vipande vinavyopishana vinavyounganishwa pamoja. |
| `chunk_overlap` |  | number | no | `5` | 0 – 30 | Urefu wa mwingiliano kati ya vipande, unaopimwa kwa sekunde, unaotumika kwa uunganishaji wa crossfade. |
| `use_sound_activity_ranking` |  | boolean | no | `false` |  | Chaguo la upangaji wa shughuli za sauti linalohitaji reranking_candidates > 1, kuwezesha upangaji upya bora kwa utenganishaji wa sehemu pekee bila kidokezo cha maandishi. Wagombea hupata alama kulingana na jinsi maeneo yao yaliyotambuliwa yasiyo kimya yanavyolingana na sehemu zilizotolewa. |
| `trim_to_span` |  | boolean | no | `false` |  | Chaguo la urefu wa tokeo kati ya sehemu iliyobainishwa pekee na sauti kamili. Kukiwezesha hukata hadi masafa ya muda ya sehemu; False huhifadhi urefu kamili na kutenga sauti lengwa kote. |
| `output_format` |  | enum (string) | no | `wav` | `wav`, `mp3` | Umbizo la sauti iliyozalishwa. |

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:

## 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 '{

        "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"

### 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.
