# Export M4A

> Official lyric-m4a download — same clip authorize as WAV

Download the official lyric-m4a for a clip. Authorization is the same as [Export WAV](/api-reference/suno/wav).

<Info>
  Request body is `AudioIdDto`: pass `clip_id`. If the response is a `taskId`, poll [Get Task Status](/api-reference/suno/task). On success, `data` includes `download_url` / `m4a_file_url`.
</Info>

```bash theme={null}
curl -X POST "https://api.mountsea.ai/suno/v2/m4a" \
  -H "Authorization: Bearer your-api-key" \
  -H "Content-Type: application/json" \
  -d '{ "clip_id": "clip_abc123" }'
```
