Start with the Vocal Range Test, then pick a tool by the question you want answered. To read your notes, use the vocal range chart, the average vocal range guide and the voice types guide.

How the Tools Work
- They run in your web browser. There is nothing to install.
- Microphone tools ask for permission first. You can stop a test at any time.
- Use headphones for the Pitch Accuracy Test, so the microphone hears your voice and not the target tone.
- Results are estimates for practice. They are not medical or professional advice.
Frequently Asked Questions
Are these tools free?
Yes. Every tool on this page is free to use, with no sign-up and no paid tier. Open a tool, allow the microphone if it asks, and start. You can run each test as often as you like.
Do they work on mobile devices?
Yes. The tools run in current mobile browsers, such as Chrome on Android and Safari on iPhone. Tap Allow when a tool asks for the microphone. A quiet room and a steady distance from the phone give clearer readings.
Do I need to install anything?
No. The tools run in your web browser, so there is no app or plugin to install. Microphone tools use the built-in microphone of your phone or computer. A headset or USB microphone also works if your browser can use it.
Can beginners use these tools?
Yes. Each tool guides you step by step and explains the result in plain words. You do not need to read music. Results use note names such as C4, and the vocal range chart linked above explains them.
Which vocal tool should I try first?
Start with the Vocal Range Test. It finds your lowest and highest notes, which most other tools build on. If you already know those notes, use the Vocal Range Calculator instead. Then pick the next tool from the table above.
