💡 How It Works
- Click "Upload Sound" button above
- Select an audio file (MP3, WAV, OGG, or WebM)
- File is converted to base64 and stored in browser localStorage
- "Custom Sound" option appears in the dropdown
- Select it and click "Test Sound" to hear it
- Custom sound persists across page refreshes
- Click 🗑️ to remove custom sound
Note: Custom sounds are stored locally in your browser. They don't upload to any server!
