Pitch Test
Choose a target manually, or prepare a target session.
No session score yetPlay the target, then start the microphone. Each attempt ends after one voiced second with a stable note, or after eight seconds. No grade is generated from silence alone.
Use one clear voice or instrument note in a quiet room. Audio stays in your browser.
In-tune share is the voiced duration within your selected tolerance. Pitch spread is the standard deviation in cents. These describe this attempt, not overall musical ability.

Microphone features need HTTPS and browser permission. Stop or hide/leave the page to release input. Reference tones pause measurement. Noise, harmonics and polyphonic sound can affect estimates.
A4 defaults to 440 Hz. An octave doubles frequency; twelve equal-tempered semitones make an octave.

The Pitch Test compares your sung note with a target you choose. Play the reference, sing comfortably, then review how much of the detected voiced time falls within the selected tolerance. This is a practical pitch-matching exercise, with cents and pitch spread to help explain the result.
Check one chosen pitch
- Select a target between C2 and C6 that is comfortable for you.
- Choose a tolerance of ±10, ±25 or ±50 cents.
- Play the target and listen before starting the microphone.
- Sing a steady vowel and finish the attempt.
- Review in-tune share, median offset and pitch spread together.
Use headphones if the reference sound might feed back into the microphone. A target tone captured from speakers can be mistaken for your voice. Stop reference playback before assessing your own sound.
The target range is a control limit, not a recommendation that every user should sing every available note. Choose an easy middle pitch before testing notes near an endpoint.
What the cents reading means
A cent is one hundredth of an equal-tempered semitone. The tool calculates the distance between the detected frequency and the selected target using their frequency ratio.
With A4 at 440 Hz, singing 445 Hz gives an offset of about +19.6 cents. Singing 435 Hz gives about −19.8 cents. Similar hertz differences do not always produce identical musical distances because the comparison is logarithmic.
Positive values indicate pitch above the target and negative values indicate pitch below it. The selected A4 reference must match the reference you intend to practice against. Changing it changes the target frequencies used for comparison.
Interpret the three result measures
| Measure | What it describes |
|---|---|
| In-tune share | Duration-weighted share of detected voiced time inside your tolerance |
| Median target offset | Middle signed cents difference from the selected target |
| Pitch spread | Variation of detected offsets around their mean |
An in-tune share of 80% means that about four fifths of the retained voiced duration met that attempt’s tolerance. It does not mean that 80% of your complete singing ability has been measured. Silence and uncertain pitch frames are not equivalent to a correctly sung note.
A median near zero can coexist with a wide spread if the voice moves above and below the target. Conversely, a stable note can have a narrow spread while remaining consistently sharp or flat.
A hypothetical attempt with two detected voiced seconds, including 1.5 seconds within the selected band, has a 75% in-tune share. The percentage refers to detected voiced duration, not simply the number of screen updates.
Choose a tolerance that matches your practice
Start with a band that makes feedback understandable. The ±50-cent option accepts a wider neighborhood around the target than ±10 cents. A tighter setting makes the same take harder to satisfy without changing the audio itself.
Keep the tolerance fixed when comparing attempts. A higher result after switching from ±10 to ±50 cents does not, by itself, show improvement.
Natural vibrato can move a note across a narrow band. Inspect the trace and spread before trying to eliminate all movement. The detector measures frequency behavior; it does not decide whether that movement is musically expressive.
Practice several targets
The prepared-target option offers sets of 5, 10, 15 or 20 notes within the selected low, middle or high group. It cycles through a major-scale pattern rather than generating an unknown full-song test.
Play each target, attempt it, then move to the next one or skip a note that is uncomfortable. Prepared attempts use short measurement windows and need usable voiced input. A skipped or untracked sound should not be mistaken for evidence about hearing or vocal health.
The Singing Test gives this sequence workflow a dedicated practice context. Use it when you want to organize several target attempts rather than focus on one note.
Make repeated attempts comparable
Keep microphone distance, target, A4 reference and tolerance the same. Use a quiet room and a moderate input level. A clipped waveform or competing instrument can change the detected pitch.
Review the saved attempts and download the available CSV if you want a record. The recent attempt list is a working session, not a permanent account history or a recording library.
Microphone input is analyzed locally. This tool does not upload or save a voice recording. If you need a summary of ordinary speech rather than target matching, choose the Voice Pitch Test.
Frequently asked questions
Is this a fine pitch hearing test?
No. It measures production against a chosen target. It does not present a controlled listening experiment to find the smallest frequency difference you can hear.
Can this tell me whether I can sing?
It can describe a limited pitch-matching task. Singing also involves timing, phrasing, articulation, breath management and musical choices that this exercise does not score.
Why is a steady note marked out of tune?
It may be steady around the wrong frequency. Check the chosen target, octave and A4 reference, then compare the signed offset with the pitch spread.
Does no detected pitch mean I failed?
No. Input permissions, level, noise or irregular sound may prevent tracking. Resolve the input problem and repeat comfortably before drawing a conclusion.
Should I use this to find my vocal range?
Use the Vocal Range Test for comfortable endpoints. A pitch-matching percentage describes performance on selected notes, not your complete usable range.
