About the Project

Voice Range Test is a free web application that helps singers discover their vocal range using real-time pitch detection. Built with modern web technologies, the tool runs entirely in your browser—no downloads, no sign-ups, no cost.

We created this tool because we believe every singer deserves access to professional-grade vocal analysis without barriers. Whether you're a vocalist teacher helping students understand their instruments, a karaoke enthusiast picking the perfect song, or a hobbyist curious about your voice, Voice Range Test is here to help.

How It Works

Using your device's microphone and advanced pitch detection algorithms, Voice Range Test analyzes your voice in real-time:

  1. Grant microphone access when prompted by your browser
  2. Start singing from your lowest comfortable note
  3. Gradually work upward to find your highest notes
  4. View your complete vocal range and voice type classification
