NOTE / TUNING

Turn a sung note into useful feedback

The detector waits for a stable fundamental before showing a note. That keeps background noise, breath attacks, and uncertain harmonics from looking like confident results.

Make each reading count

Select your voice range if an octave looks wrong, move close to the microphone, and sustain one note. Use the cents meter to adjust toward the center line.

Singing note detector FAQ

Why does the note disappear while I sing?

PitchDetect intentionally hides weak or unstable frames. Hold a clear monophonic note, reduce background sound, and choose a voice range when octave ambiguity is likely.
