# 🎙️ 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
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](audio_url)

---

**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](audio_url)

---

**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`:

```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](https://elevenlabs.io/app/settings/api-keys).

### Optional (for fal.ai music & SFX models)

```json
"FAL_KEY": "your_fal_key_here"
```

Get your key at [fal.ai/dashboard/keys](https://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)

```bash
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](https://elevenlabs.io/app/settings/api-keys) |
| `FAL_KEY` | Music generation | [fal.ai/dashboard/keys](https://fal.ai/dashboard/keys) |
| `VALID_PRO_KEYS` | (Optional) Restrict access | Comma-separated list of allowed client keys |

### Point cli.js to Your Proxy

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

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

```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`.
