Detect any of the twelve semitones through your microphone and see the nearest note, frequency, and cents offset without choosing an instrument preset.
A chromatic tuner listens for any pitched note instead of limiting detection to the strings of one instrument. It identifies the nearest semitone and measures the distance from that note in cents.
The target setup on this page is All 12 chromatic notes.
Pitch analysis runs continuously in the browser and displays the nearest target, frequency, and cents difference.
The tuner shows whether the current note needs to move up, move down, or is within the in-tune range.
Select a visible target to hear a clean reference pitch when you want to compare the instrument by ear.
Microphone samples are analyzed locally and are not uploaded as an audio recording.
Tune in a quiet room and play only one clear note or open string at a time.
Start with All 12 chromatic notes. Available alternatives include Any pitched instrument or custom tuning when you already know the target note.
Allow microphone access, keep the instrument close enough for a clean signal, and avoid other sustained sounds.
Sustain one note and read the detected note and cents offset.
Move gradually toward the center, then repeat every target because changing one string can slightly affect the others.
Use the dedicated preset when the target notes and physical string order matter more than a general chromatic reading.
Tune notes that are not included in a standard guitar, bass, ukulele, or orchestral-string preset.
Check sustained notes from flute, saxophone, clarinet, trumpet, and other single-note sources.
Sustain one vocal note and compare it with the closest semitone and cents reading.
Move A4 between 430 Hz and 450 Hz for orchestral, historical, or recording-specific references.
Both use the same pitch detector, but they organize targets differently.
| Chromatic Tuner preset | Chromatic mode | |
|---|---|---|
| Targets | All 12 chromatic notes | All twelve semitones |
| Visual layout | Chromatic note wheel | Detected note and cents |
| Best for | Any known target note | Custom tunings and other pitched instruments |
| Tuning choice | Any pitched instrument or custom tuning when you already know the target note | No instrument tuning required |
A dedicated preset is easier when you want the correct string order. Chromatic mode is more flexible when you already know the target note.
Yes. It runs in a supported browser without requiring an account or installing a tuning app.
The default targets are All 12 chromatic notes.
Yes. Allow microphone permission, keep the device near the instrument, and play in a quiet place for a more stable reading.
One semitone contains 100 cents. A negative reading is flat, a positive reading is sharp, and a value close to zero is in tune.
Other strings, room noise, overtones, and a hard attack can compete with the fundamental. Mute unused strings and read the note after it settles.
No. Live microphone analysis stays in the browser and the tuner does not create or upload an audio recording.
Find BPM from a song, loop, or recording, review confidence, and compare half-time or double-time readings.
Analyze a song, loop, acapella, instrumental, or recording locally, then review confidence and compatible keys.
Detect chord changes, review a synchronized timeline, correct labels, and export a TXT or CSV chord chart.
Select notes or mark a guitar shape, hear the voicing, and compare likely chord names.
Search common major, minor, seventh, and major seventh shapes, hear them, and open detailed references.
Compare chord diagrams by root, quality, and difficulty, then open a detailed reference or print the chart.
Measure beats per minute from your taps with timing consistency feedback.
Use your microphone to tune guitar, bass, ukulele, cavaquinho, violin-family instruments, mandolin, balalaika, banjo, or any chromatic instrument.
Use a live microphone or recording to measure your lowest note, highest note, octave span, and a range-based voice type estimate.
Analyze complete audio files with EBU R128 loudness measurement in your browser.
Check six frequencies in each ear and compare both sides with an instant visual result.
Run a guided high-frequency check or mark your cutoff during a continuous 20 Hz to 20 kHz sweep.
Verify speaker channels and run controlled playback checks directly in your browser.
Verify headphone channels, stereo movement, bass playback, noise, and phase online.
