Piano Tuner overview

Piano Tuner is a 12-note chromatic scale strobe tuner and partial analyzer application that utilizes sound input devices such as built-in microphone, line in and iSight.

Strobe tuners are extremely accurate compare to regular tuners with a needle or LEDs. The slightest difference between the actual pitch and the ideal pitch accumulates over time and appears as a movement on the strobe tuning meter.

Piano Tuner can be used by someone who wants to learn how to tune a piano by using a tuning lever and also be used by a professional piano tuner to help the tuning process.

You can now use the Partials window to figure out the cent offsets of the stretch table for your piano, or you can use the Partials window alone to tune your piano directly without a stretch table.

  • Tuning: 12-note chromatic scale.
  • Temperaments: Customizable (±50 cents). Supports Scala Scale (.scl) files.
