Audio Control

Quick Start

Control the device'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

curl -s http://127.0.0.1:5001/audio

Response:

{
  "output_device": 0,
  "input_device": 1,
  "available": true
}

Set volume

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

curl -s http://127.0.0.1:5001/audio/volume

Response: {"control": "Speaker", "volume": 70}

Play test tone

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).
