A practical workflow

  1. User clicks 'Start Tuning' and allows microphone access, then plays one string at a time while observing the tuner's response to adjust string tension.
  2. The tuner detects the frequency of the played string and converts it to the corresponding note and octave, showing deviation in cents from the standard pitch.
  3. Visual feedback with meters and color indicators guides the user to tighten or loosen strings to achieve perfect tuning.
