Voice pitch analyzer

Analyze vocal pitch in real time from your microphone. See note names, Hz, cents deviation, stability, and a live pitch curve—free in your browser.

What is a voice pitch analyzer?

A voice pitch analyzer listens through your microphone, estimates the fundamental frequency of your voice, and shows the closest musical note, Hz value, and cents deviation in real time. This vocal pitch monitor helps singers and speakers answer what note am I singing while tracking stability across a practice session. For raw Hz without note names, use /frequency-detector. To review a finished recording, use /audio-file-pitch-detector.

Vocal pitch analyzer features

Real-time note detection with session stats and a scrolling pitch curve.

  1. Live note and cents readout: See the current note name, Hz, and cents from equal temperament as you sing or speak.
  2. Pitch stability score: Session stability reflects how steadily you hold pitch based on cents variance.
  3. Low, average, and high Hz: The tool logs the lowest, mean, and highest frequencies detected during the session.
  4. Scrolling pitch curve: Watch pitch movement over time to spot drift, vibrato, and phrase endings.
  5. Concert A reference: Switch A4 between 440, 432, and 442 Hz before you start analysis.
  6. Local microphone processing: Audio is analyzed in your browser and is not uploaded to a server.

How to use the vocal pitch detector

Start analyzing voice pitch in a few steps.

  1. Start analysis: Click Start analysis and allow microphone access when prompted.
  2. Sing a steady vowel: Hold ah or hum for a few seconds at a comfortable volume in a quiet room.
  3. Read note, Hz, and cents: Use the large note display and cents meter to see how close you are to the pitch center.
  4. Review stability and range: Check the stability percentage and lowest/highest Hz logged during the session.

Tips for accurate vocal pitch detection

Get cleaner readings from this online pitch detector.

  1. Use a quiet room: Fans, traffic, and room hum add noise that can hide your vocal pitch.
  2. Hold one note: Sustained vowels work best. Fast runs and slides are harder to read clearly.
  3. Stay 20–30 cm from the mic: A consistent distance helps level stay above the silence gate on laptop mics.
  4. Try medium smoothing first: Increase smoothing if the display flickers; lower it for faster response.
  5. Pair with file review: Practice live here, then upload the same take to /audio-file-pitch-detector for a full trace.
  6. Train pitch memory: After checking notes, challenge yourself on /sound-memory-game.
