Help & Tips
  • When prompted, click Allow to enable your microphone.
  • For best results, use in a quiet room and hold notes steadily for 1-2 seconds.
  • If the pitch reading is unstable, try increasing the “Smoothing” slider slightly.
  • If no sound is detected, try decreasing the “Noise Gate” slider (moving it to the left).

How to Use the Vocal Range Calculator

This tool runs entirely in your browser for complete privacy. No audio is ever recorded, stored, or uploaded. Follow these steps to find your range in under a minute.

1. ▶️ Start / Allow Mic

Click the Start / Allow Mic button and grant permission when your browser asks to use your microphone.

2. 📉 Capture Lowest Note

Sing your lowest comfortable note. Hold it steady for 1–2 seconds until it locks, then click Capture Lowest.

3. 📈 Capture Highest Note

Sing your highest note without straining. Hold it for 1–2 seconds, then click Capture Highest.

4. 📊 Finish & Calculate

Click Finish & Calculate to see your full range, total span (in octaves and semitones), and suggested voice type.

Options & Settings

  • Include falsetto: Check this box to include your head voice or falsetto for your complete range.
  • A4 reference: Sets the tuning standard (440Hz is standard for most music).
  • Noise Gate: Raise the slider slightly if the tool picks up background room noise.
  • Smoothing: Increase this slider if the live pitch display flickers too much.

Troubleshooting

  • No sound detected? Try lowering the Noise Gate slider.
  • Pitch flickers? Raise the Smoothing slider slightly.
  • Mic blocked? Refresh the page or check your browser’s site permissions to allow access.

Pro Tip: For the most accurate results, always warm up your voice first, test in a quiet room, and focus on proper breathing support while holding notes steadily.

Accuracy & Privacy You Can Trust

This tool uses modern audio processing to analyze your voice in real time, directly in your browser. Your privacy is guaranteed: no audio is ever recorded, uploaded, or stored.

How Pitch Detection Works

  • Web Audio API: Captures low-latency microphone input directly from your browser.
  • Real-time Analysis: Uses a robust pitch detection algorithm (YIN/pYIN) to reliably find the fundamental frequency (F0) of your voice.
  • Jitter Reduction: Applies signal smoothing and a noise gate to filter out background noise and stabilize the detected note.

Factors for Best Accuracy

  • Quiet Environment: Test in a quiet room to minimize background noise interference.
  • Steady Notes: Hold each note steadily for at least 1–2 seconds to allow the algorithm to lock on.
  • Good Microphone: A headset or external microphone will typically yield better results than a laptop’s built-in mic.
  • Adjust Settings: If the note flickers, try raising the Noise Gate and Smoothing sliders.
A4 Reference: Sets the concert pitch for tuning (440 Hz is standard). Falsetto Toggle: Includes your upper register for a complete range measurement.

Results are for educational purposes and should be considered approximate.

Frequently Asked Questions

Quick answers to common questions about the tool’s accuracy, privacy, and how to get the best results.

How accurate is the calculator?

The tool uses real-time pitch detection with signal smoothing and a noise gate. In a quiet environment with steady notes, the typical accuracy is within ±10–15 cents of the true pitch.

Is my voice recorded or stored?

No. All audio processing happens locally in your browser via the Web Audio API. Your voice is never recorded, uploaded, or stored on any server.

Do I need a special microphone?

A standard built-in microphone works, but a headset or external USB mic can improve accuracy by reducing background noise. Always test in a quiet room and hold notes for 1–2 seconds.

What do “Noise Gate” and “Smoothing” do?

Noise Gate filters out quiet background noise; increase its value if the tool detects random notes when you’re not singing. Smoothing reduces pitch jitter; raise it if the displayed note flickers unstably.

Should I include falsetto?

Check “Include falsetto” to measure your absolute highest notes for a complete range. For your core, practical range (tessitura), it’s often better to measure only your comfortable chest and connected head voice notes.

Why does the pitch jump or flicker?

This can be caused by background noise, an inconsistent tone, or being too far from the mic. First, try moving closer and reducing noise. If it persists, slightly raise the Noise Gate and Smoothing sliders.

What does A4 (440/442 Hz) change?

This setting adjusts the concert pitch reference used to name notes. A4 at 440 Hz is the global standard, while 442 Hz is sometimes used by orchestras and ensembles for a slightly brighter sound.

How is the suggested voice type decided?

The tool compares the midpoint of your captured lowest and highest notes to the standard ranges for common voice types (e.g., Tenor: C3–C5). See the Voice Type Chart or learn more about all Voice Types.

The results look wrong—what should I do?

First, do a few simple warm-ups. Ensure you’ve allowed microphone permissions and are in a quiet room. Re-test, holding notes steadily. If needed, try adjusting the Noise Gate and Smoothing settings.
