🎙️ VideoAgent Audio Studio

Use when: User asks to generate speech, narrate text, create a voice-over, compose music, or produce a sound effect.

VideoAgent Audio Studio is a smart audio dispatcher. It analyzes your request and routes it to the best available model — ElevenLabs for speech and music, fal.ai for fast SFX — and returns a ready-to-use audio URL.

Quick Reference

Request Type	Best Model	Latency
Narrate text / Voice-over	elevenlabs-tts-v3	~3s
Low-latency TTS (real-time)	elevenlabs-tts-turbo	<1s
Background music	cassetteai-music	~15s
Sound effect	elevenlabs-sfx	~5s
Clone a voice from audio	elevenlabs-voice-clone	~10s

How to Use

1. Start the AudioMind server (once per session)

bash {baseDir}/tools/start_server.sh

This starts the ElevenLabs MCP server on port 8124. The skill uses it for all audio generation.

2. Route the request

Analyze the user's request and call the appropriate tool via the MCP server:

Text-to-Speech (TTS)

When user asks to "narrate", "read aloud", "say", or "create a voice-over":

Use MCP tool: text_to_speech
  text: "<the text to narrate>"
  voice_id: "JBFqnCBsd6RMkjVDRZzb"   # Default: "George" (professional, neutral)
  model_id: "eleven_multilingual_v2"   # Use "eleven_turbo_v2_5" for low latency

Music Generation

When user asks to "compose", "create background music", or "make a soundtrack":

Use MCP tool: text_to_sound_effects  (via cassetteai-music on fal.ai)
  prompt: "<music description, e.g. 'upbeat lo-fi hip hop, 90 seconds'>"
  duration_seconds: <duration>

Sound Effect (SFX)

When user asks for a specific sound (e.g., "a door creaking", "rain on a window"):

Use MCP tool: text_to_sound_effects
  text: "<sound description>"
  duration_seconds: <1-22>

Voice Cloning

When user provides an audio sample and wants to clone the voice:

Use MCP tool: voice_add
  name: "<voice name>"
  files: ["<audio_file_url>"]

Example Conversations

User: "Voice this text for me: Welcome to our product launch"

→ Route to: text_to_speech
  text: "Welcome to our product launch"
  voice_id: "JBFqnCBsd6RMkjVDRZzb"
  model_id: "eleven_multilingual_v2"

🎙️ Voiceover done! Listen here

User: "Generate 60 seconds of relaxing background music for a podcast"

→ Route to: cassetteai-music (fal.ai)
  prompt: "relaxing lo-fi background music for a podcast, gentle piano and soft beats, 60 seconds"
  duration_seconds: 60

🎵 Background music ready! Listen here

---

User: "Generate a sci-fi style door opening sound effect"

→ Route to: text_to_sound_effects
  text: "a futuristic sci-fi door sliding open with a hydraulic hiss"
  duration_seconds: 3

Setup

Required

Set ELEVENLABS_API_KEY in ~/.openclaw/openclaw.json:

{
  "skills": {
    "entries": {
      "videoagent-audio-studio": {
        "enabled": true,
        "env": {
          "ELEVENLABS_API_KEY": "your_elevenlabs_key_here"
        }
      }
    }
  }
}

Get your key at elevenlabs.io/app/settings/api-keys.

Optional (for fal.ai music & SFX models)

"FAL_KEY": "your_fal_key_here"

Get your key at fal.ai/dashboard/keys.

---

Self-Hosting the Proxy

The cli.js connects to a hosted proxy by default. If you want full control — or need to serve users in regions where vercel.app is blocked — you can deploy your own instance from the proxy/ directory.

Quick Deploy (Vercel)

cd proxy
npm install
vercel --prod

Environment Variables

Set these in your Vercel project (Dashboard → Settings → Environment Variables):

Variable	Required For	Where to Get
ELEVENLABS_API_KEY	TTS, SFX, Voice Clone	elevenlabs.io/app/settings/api-keys
FAL_KEY	Music generation	fal.ai/dashboard/keys
VALID_PRO_KEYS	(Optional) Restrict access	Comma-separated list of allowed client keys

Point cli.js to Your Proxy

export AUDIOMIND_PROXY_URL="https://your-domain.com/api/audio"

Or set it in ~/.openclaw/openclaw.json:

{
  "skills": {
    "entries": {
      "videoagent-audio-studio": {
        "env": {
          "AUDIOMIND_PROXY_URL": "https://your-domain.com/api/audio"
        }
      }
    }
  }
}

Custom Domain (Recommended)

If your users are in mainland China, bind a custom domain in Vercel Dashboard → Settings → Domains to avoid DNS issues with vercel.app.
