How it works
Three simple steps
- Click Start. The tool will not request microphone access before you click.
- Allow microphone access. Your browser asks for permission and uses the microphone only on this page.
- See your pitch in real time. Sing or speak a steady sound and view Hz, note, cents, and session summary values.
Your audio stays in your browser. We do not upload or store your audio.
What it measures
Hz, note, octave, cents, and session range
Frequency in Hz shows how fast your voice is vibrating. Musical note shows the closest note name, such as A3 or C4. Cents show how close your pitch is to the nearest note.
Lowest, highest, and average pitch summarize stable readings from your current session. This tool is for general pitch reference only and is not a substitute for guidance from a vocal coach, clinician, or other qualified professional.
