This free voice pitch analyzer shows your singing pitch live on a vocal pitch monitor. Sing into your microphone and watch your voice draw a line across piano-key note lanes, with the note, frequency and cents, and a plain-language reading of your pitch curve: steady, sliding, wobbly or vibrato. It also measures your average pitch, range, steadiness and vibrato, and records takes you can play back.

How to Use the Voice Pitch Analyzer
- Choose your voice (lower, higher or child’s voice) so the monitor stays in your range.
- Press Start and allow the microphone. It listens to the room for a moment first.
- Sing a phrase, a scale or one long note. Your pitch is drawn as a violet line; the grey rows are the black keys of a piano.
- Read the curve summary under the note: Steady note, Sliding up, Wobbly or Vibrato: 5.6 Hz, ±40¢.
- Press ● Record take to keep a phrase, then play it back and watch its pitch curve with the playback line. Use Pause to freeze the monitor.
How to Read Your Pitch Curve
| What you see | What it means | What to try |
|---|---|---|
| A flat line on one lane | A steady, centred note | Keep it: this is good pitch control |
| A regular wave around the lane | Vibrato | Check its rate and width in the stats |
| A curve rising into the note | Scooping: starting below the note | Aim for the note from the start |
| The end of a phrase drooping | Going flat as breath runs out | Support the breath to the end of the phrase |
| An uneven, jagged line | Unsteady pitch | Sing softer and slower; hold single notes |
| A line between two lanes | Sharp or flat by up to half a semitone | Use a target note and adjust until it sits on the line |
What the Numbers Mean
- Average pitch: the middle (median) note of everything you sang, with its frequency in Hz.
- Range: from your lowest to your highest regular notes (the occasional stray note is left out).
- In tune: the share of time you were within ±10 cents of a note.
- Steadiness: how still your pitch stayed on held notes; above 85% is very steady.
- Vibrato: the rate (waves per second) and width (how far above and below the note) of your vibrato.
You can download every reading as a CSV file to compare sessions in a spreadsheet.
Vibrato: Rate and Width
A natural singing vibrato usually moves about 5 to 7 times a second and swings roughly 20 to 100 cents above and below the note; classical singers tend toward the wider end, pop singers toward a narrower, later vibrato. A rate much slower than 4 per second sounds like a wobble, and a very fast, narrow one like a bleat. The analyzer reports vibrato only when the waves are regular, so a shaky note is not counted as vibrato. More in what is vibrato.
Practise With a Target Note
Pick a Target note under the monitor and press Play target to hear it. A dashed green line marks the note, and the readout tells you how far above or below it you are. Sing, adjust until your line sits on the target and hold it. For a structured routine, see how to improve pitch accuracy.
Record and Compare Your Takes
Takes are recorded on your device only and are never uploaded. Record the same phrase several times, play each one back and compare the curves: a better take shows cleaner note changes, less scooping and flatter held notes. Takes disappear when you leave the page, so download anything you want to keep as a CSV first.
Which Voice Tool Do You Need?
| Tool | Best for |
|---|---|
| Voice pitch analyzer (this page) | Watching your pitch over whole phrases, vibrato, steadiness and takes |
| Voice Hz test | One number: the average frequency of your speaking voice |
| Singing note detector | Finding which note you are singing, one note at a time |
| Vocal range test | Your lowest and highest notes and your voice type |
How the different voice types compare in range is explained in types of vocal ranges.
Tips for Accurate Analysis
- Use a quiet room, turn off music and hold the phone or laptop 20–50 cm away.
- Headphones stop reference tones from being picked up by the microphone.
- Sing on open vowels such as “ah” or “oo”; consonants and breathy tones give gaps in the line.
- If your line jumps up or down an octave, choose your voice type at the top.
Frequently Asked Questions
What does a voice pitch analyzer do?
It measures the pitch of your voice many times a second and draws it over time, so you can see whether you are on the note, how steady you are and how you move between notes.
Is this a vocal pitch monitor app?
It works like one, in your browser: nothing to install on iPhone, Android or a computer.
Why is my vibrato shown as “none detected”?
Either you sang without vibrato, or the waves were too irregular or too small to measure. Hold a note for at least a second with your natural vibrato.
Is my voice recorded or uploaded?
