🔔 Webchat Audio Notifications

Browser audio notifications for Moltbot/Clawdbot webchat. Plays a notification sound when new messages arrive - but only when the tab is in the background.

Features

• 🔔 Smart notifications - Only plays when tab is hidden
• 🎚️ Volume control - Adjustable 0-100%
• 🎵 5 intensity levels - Whisper (1) to impossible-to-miss (5)
• 📁 Custom sounds - Upload your own (MP3, WAV, OGG, WebM)
• 🔕 Easy toggle - Enable/disable with one click
• 💾 Persistent settings - Preferences saved in localStorage
• 📱 Mobile-friendly - Graceful degradation on mobile
• 🚫 Autoplay handling - Respects browser policies
• ⏱️ Cooldown - Prevents spam (3s between alerts)
• 🐞 Debug mode - Optional logging

Quick Start

Test the POC

cd examples
python3 -m http.server 8080
# Open http://localhost:8080/test.html

Test steps:

1. Switch to another tab
2. Click "Trigger Notification"
3. Hear the sound! 🔊

Basic Integration

// Initialize
const notifier = new WebchatNotifications({
  soundPath: './sounds',
  soundName: 'level3',  // Medium intensity (default)
  defaultVolume: 0.7
});

await notifier.init();

// Trigger on new message
socket.on('message', () => notifier.notify());

// Use different levels for different events
socket.on('mention', () => {
  notifier.setSound('level5');  // Loudest for mentions
  notifier.notify();
});

API

Constructor Options

new WebchatNotifications({
  soundPath: './sounds',               // Path to sounds directory
  soundName: 'level3',                 // level1 (whisper) to level5 (very loud)
  defaultVolume: 0.7,                  // 0.0 to 1.0
  cooldownMs: 3000,                    // Min time between alerts
  enableButton: true,                  // Show enable prompt
  debug: false                         // Console logging
});

Intensity Levels:

• level1 - Whisper (9.5KB) - Most subtle
• level2 - Soft (12KB) - Gentle

Configuration Examples

Simple

const notifier = new WebchatNotifications();
await notifier.init();
notifier.notify();

Advanced

const notifier = new WebchatNotifications({
  soundPath: '/assets/sounds',
  soundName: 'level2',  // Start with soft
  defaultVolume: 0.8,
  cooldownMs: 5000,
  debug: true
});

await notifier.init();

// Regular messages = soft
socket.on('message', () => {
  notifier.setSound('level2');
  notifier.notify();
});

// Mentions = very loud
socket.on('mention', () => {
  notifier.setSound('level5');
  notifier.notify();
});

// DMs = loud
socket.on('dm', () => {
  notifier.setSound('level4');
  notifier.notify();
});

With UI Controls

<input type="range" min="0" max="100" 
       onchange="notifier.setVolume(this.value / 100)">
<button onclick="notifier.test()">Test 🔊</button>

Troubleshooting

No sound?

• Click page first (autoplay restriction)
• Check tab is actually hidden
• Verify volume > 0
• Check console for errors

Sound plays when tab active?

• Enable debug mode
• Check for "Tab is visible, skipping" message
• Report as bug if missing

Mobile not working?

• iOS requires user gesture per play
• Consider visual fallback (flashing favicon)

Performance

• Bundle: ~122KB total (minified)
• Memory: ~2MB during playback
• CPU: Negligible (browser-native)
• Network: One-time download, cached

Security

• ✅ No external requests
• ✅ localStorage only
• ✅ No tracking
• ✅ No special permissions

• Per-event sounds (mention, DM, etc.)
• Visual fallback (favicon flash)
• System notifications API
• Settings UI component
• Do Not Disturb mode
