# Audio Control ## Quick Start Control the lamp's speaker and microphone hardware directly. Use this for volume adjustments, test tones, and raw audio recording. This is LOW-LEVEL hardware control only. ## Workflow 1. Determine the user's audio hardware need: - Volume adjustment -> use `POST /audio/volume` - Check current volume -> use `GET /audio/volume` - Diagnostics / test -> use `POST /audio/play-tone` - Raw recording -> use `POST /audio/record` 2. Optionally check device availability first: `GET /audio` 3. Execute the appropriate API call 4. Confirm the action to the user ## Examples Input: "Louder please" / "Turn it up" Output: Check current volume with `GET /audio/volume`, then increase by ~15 with `POST /audio/volume`. Confirm: "Volume set to 85%." Input: "Set volume to 50%" Output: Call `POST /audio/volume` with `{"volume": 50}`. Confirm: "Volume set to 50%." Input: "Mute" / "Too loud" Output: Call `POST /audio/volume` with `{"volume": 0}`. Confirm: "Muted." Input: "I can't hear you" Output: Check current volume with `GET /audio/volume`, then increase it. Confirm with the new level. Input: "Say something" / "Tell me a joke" Output: Do NOT use this skill. Just reply normally — your voice pipeline handles TTS automatically. ## Tools Use `Bash` with `curl` to call the HTTP API at `http://127.0.0.1:5001`. ### Check audio devices ```bash curl -s http://127.0.0.1:5001/audio ``` Response: ```json { "output_device": 0, "input_device": 1, "available": true } ``` ### Set volume ```bash curl -s -X POST http://127.0.0.1:5001/audio/volume \ -H "Content-Type: application/json" \ -d '{"volume": 70}' ``` Volume range: 0 (mute) to 100 (max). ### Get current volume ```bash curl -s http://127.0.0.1:5001/audio/volume ``` Response: `{"control": "Speaker", "volume": 70}` ### Play test tone ```bash curl -s -X POST "http://127.0.0.1:5001/audio/play-tone?frequency=440&duration_ms=500" ``` Plays a sine wave. Use for audio testing only. Keep it short (< 1 second). ### Record audio ```bash curl -s -X POST "http://127.0.0.1:5001/audio/record?duration_ms=3000" ``` Records from the microphone and returns a WAV file. ## Error Handling - If `GET /audio` returns `"available": false`, inform the user: "The speaker/microphone is not connected right now." - If the API is unreachable, inform the user: "I couldn't access the audio hardware. The service may be unavailable." - If the user requests a volume outside 0-100, clamp to the valid range. ## Rules - Default volume is usually 70%. Adjust based on user preference. - **Audio = volume knob, raw mic recording, test beeps.** No AI speech processing. - **Voice = AI-powered speech (TTS/STT).** Uses Audio hardware underneath but is a separate skill. - When the user says "I can't hear you" or "too loud", adjust volume via this skill. - Do NOT use this skill for TTS or speech output — that is handled by the **Voice** skill and the automatic voice pipeline. ## Output Template ``` [Audio] {action} — {details} ``` Examples: - `[Audio] Volume set — 70%` - `[Audio] Volume set — muted (0%)` - `[Audio] Test tone played — 440Hz, 500ms` - `[Audio] Recording captured — 3000ms`
