Frequently Asked Questions
How accurate is pitch detection?
Within 1 cent for sustained tones. Noisy environments or very low/high pitches may reduce accuracy.
Can I use it as a guitar tuner?
Yes. Play each string and check the note name and cents display. Tune until the offset shows 0 cents.
What instruments work best?
Monophonic instruments (voice, flute, guitar single notes) work best. Chords and polyphonic sources are harder to track — use the Chord Detector for those.
