Reference pitch
440 Hz
No stable note detected yet. Sing or play a sustained single note close to your microphone.
Calibration
Keep 440 Hz for standard tuning, or bump to 442 Hz if your ensemble tunes slightly sharper.
Best results
- Use a quiet room and stay close to the microphone.
- Play or sing one sustained note at a time.
- Avoid heavy background chords or reverb while detecting pitch.
Live detector
See pitch drift on a note-by-note piano roll
This view shows where your note sits in musical space, how long it stays stable, and whether it drifts sharp or flat before it settles.
Pitch piano roll
A note-lane view of the last 15 seconds, with stable notes as blocks and live pitch drift as a trace.
Use cases
Built for voices and instruments, not just guitars
This page is the broad detector. When you need instrument-specific workflows, you can step into the dedicated tuner tools later.
Voice practice
Check whether your sung note is centered before moving on to scales, intervals, and ear training.
Guitar and bass
Verify any fretted or open note before switching to the dedicated Guitar Tuner for string-by-string tuning.
Piano and keys
Spot-test single notes when you want a quick pitch read without opening a heavier audio analyzer.
Violin and winds
Hold a sustained note and watch how steady your intonation stays across the phrase.
FAQ
Quick answers before you start listening
How is this different from the Guitar Tuner?
Pitch Detector identifies any single note it hears. Guitar Tuner is optimized for string-by-string tuning targets, alternate tunings, and guitar-specific workflows.
Can I use it for singing?
Yes. It works well for sustained single notes from voice and most melodic instruments. Start close to the microphone and avoid background harmony.
Why does the note sometimes flicker?
Pitch detection gets less stable with noise, vibrato, or very short sounds. Hold the note a little longer to let the detector settle.
