See the setup-api-key skill.\"\nallowed-tools: Bash, Read, Write, mcp__sonilo__*\n---\n\n# Sonilo Audio Ducking\n\nAutomatically duck a music bed under a voice track: Sonilo lowers the music wherever the voice is speaking and lifts it back in the gaps, then returns the mixed result. The voice input may be a video — its audio track is used as the voice, and the ducked mix is muxed back into a new video.\n\n> **Setup:** See the [setup-api-key](../setup-api-key) skill.\n\n> ⚠️ **Cost:** makes an API call that may incur charges. Only call when explicitly requested.\n\n## Transport: MCP or CLI\n\nPick one at the start of the session and stay on it. Do not mix the two inside\na single job, and do not announce the choice.\n\n1. **Sonilo MCP tools visible in this session** (`audio_ducking` and friends) — use them. This is the preferred path: it needs no shell, and it is the only one that survives a very long generation. If a call fails to authenticate — rather than failing on its inputs — this transport is not usable in this session: go to 2 instead of retrying it.\n2. **No usable Sonilo MCP tools, but `sonilo account` exits 0** — use the CLI commands below. Same API, same account, same credential file. Probe with `sonilo account`, not `sonilo whoami`: whoami exits 0 even when signed out, so it cannot tell the two states apart.\n3. **Neither** — stop and run the [setup-api-key](../setup-api-key) skill. Do not call `api.sonilo.com` with curl to work around it; both transports handle uploads, polling and retries that a bare request does not.\n\n## Quick Start\n\n### MCP tool call (recommended)\n\n```\naudio_ducking(\n    voice_path=\"~/Desktop/interview.mp4\",\n    music_path=\"~/Desktop/background-track.wav\"\n)\n```\n\n### Python (`pip install \"sonilo>=0.13\"`)\n\n```python\nfrom sonilo import Sonilo\n\nclient = Sonilo()  # reads SONILO_API_KEY\n\nresult = client.audio_ducking.generate(\n    voice=\"interview.mp4\",  # audio or video; also voice_url=\n    music=\"background-track.wav\",  # audio only; also music_url=\n)\nresult.save(\"ducked.mp4\" if result.output_type == \"video\" else \"ducked.wav\")\n```\n\n### JavaScript / TypeScript (`npm install sonilo@>=0.14`)\n\n```ts\nimport { SoniloClient, download } from \"sonilo\";\nimport { writeFile } from \"node:fs/promises\";\n\nconst client = new SoniloClient(); // reads SONILO_API_KEY\n\nconst result = await client.audioDucking.generate({\n  voice: \"./interview.mp4\", // audio or video; also voiceUrl\n  musicUrl: \"https://example.com/background-track.wav\", // audio only; also music\n});\nawait writeFile(\n  result.output_type === \"video\" ? \"ducked.mp4\" : \"ducked.wav\",\n  await download(result.output_url!),\n);\n```\n\n### CLI (`npm install -g sonilo-cli` or `pip install sonilo-cli`)\n\n```bash\nsonilo audio-ducking --voice interview.mp4 --music-url https://example.com/background-track.wav\n```\n\nAlways async under the hood — the CLI submits and polls for you. Exactly one of `--voice`/`--voice-url` and one of `--music`/`--music-url`. The default output name follows what comes back (`output.wav`, or `output.mp4` when the voice input was a video); `--output` overrides it. A local `--music` file must have an audio extension — the CLI rejects a video there up front, for the same reason the MCP tool does.\n\n### cURL (raw REST API, no MCP host)\n\n```bash\ncurl -X POST \"https://api.sonilo.com/v1/audio-ducking\" \\\n  -H \"Authorization: Bearer $SONILO_API_KEY\" \\\n  -F \"voice_file=@interview.mp4\" \\\n  -F \"music_file=@background-track.wav\"\n# -> {\"task_id\": \"...\"}  poll GET /v1/tasks/{task_id}\n```\n\nA local file uses the `voice_file`/`music_file` multipart fields; a remote source uses `voice_url`/`music_url` form fields instead (mix and match freely between the two inputs).\n\n## Tool\n\n| Tool | Description |\n|------|-------------|\n| `audio_ducking(voice_path? \\| voice_url?, music_path? \\| music_url?, output_directory?)` | Mix `music` under `voice`, ducking automatically wherever the voice speaks. |\n\n## Parameters\n\n| Parameter | Type | Notes |\n|-----------|------|-------|\n| `voice_path` | string | Absolute path, or relative to `SONILO_MCP_BASE_PATH`. **Audio or video**: `.wav/.mp3/.m4a/.aac/.ogg/.flac` or `.mp4/.mov/.avi/.wmv/.webm/.mkv`. |\n| `voice_url` | string | HTTPS URL to the voice audio/video. Exactly one of `voice_path`/`voice_url`. |\n| `music_path` | string | Absolute path, or relative to the base path. **Audio only** — a video here is not treated specially and will be mishandled. |\n| `music_url` | string | HTTPS URL to the music audio. Exactly one of `music_path`/`music_url`. |\n| `output_directory` | string | Defaults to `SONILO_MCP_BASE_PATH`. |\n\nEach input is capped at **360 seconds (6 minutes)** and by the account's upload-size limit (typically 300 MB).\n\n## Workflow Tips\n\n- **This tool takes two already-existing tracks** — it does not generate music or SFX itself. If you need to generate the music bed first, use the [text-to-music](../text-to-music) or [video-to-music](../video-to-music) skill (`text_to_music`/`video_to_music`), then feed the result in here as `music_path`.\n- **The voice input can be a video.** If the user hands you a talking-head clip or an interview and a separate music file, pass the video straight through as `voice_path` — Sonilo extracts its audio track, ducks the music under it, and re-muxes the ducked mix back into a new video automatically.\n- **Prefer [video-to-sound](../video-to-sound) or `video_to_music(ducking=true)`** when the music itself is also being *generated* for that same video — those tools duck internally as part of generation, so you don't need a separate ducking call. Reach for `audio_ducking` specifically when the music track is fixed/external and you just need the mix.\n\n## Recovering a Timed-Out Call\n\nThis tool submits an async task on the backend. If the call times out, the error carries a `task_id` — the job keeps running (already charged). Call `get_sfx_task(task_id)` later (`get_generation_task(task_id)` on the hosted server); see [task-recovery](../task-recovery).\n\n## Output Files\n\nA single file: a `.wav` if the voice input was audio, or a `.mp4` (ducked mix re-muxed in) if the voice input was a video. Named after the voice input (e.g. `interview.mp4` → `interview-ducked.mp4`), falling back to `ducked-<first 8 chars of the task id>`.\n\n## Error Handling\n\nCommon errors: `401` invalid key, `402` insufficient balance / trial exhausted, `413` file too large, `422` invalid parameters, `429` rate limit. See the [account](../account) skill.\n","tagline":"Duck a music bed under a voice track using Sonilo — automatically lowers the music wherever the voice speaks and lifts it back in the gaps.
