In this article, we will focus on the Tunelab app for iPhone/iPad, which is also known as Tunelab 31 Ipa. This app is compatible with iOS 9.0 or later, and requires a microphone or an external audio interface to capture the sound of the piano. The app has a simple and intuitive interface, which consists of four quadrants: the spectrum display, the tuning meter, the note selector, and the settings menu.
The Spectrum Display
The spectrum display shows the frequency spectrum of the sound captured by the microphone. It helps users to identify the partials of the note being tuned, and to adjust the tuning accordingly. The spectrum display can be zoomed in or out by pinching or spreading two fingers on the screen. Users can also tap on a peak to see its frequency and cents deviation from the target pitch.
The Tuning Meter
The tuning meter shows the deviation of the note being tuned from the target pitch in cents. It also shows the target frequency and the octave number of the note. The tuning meter has a green zone in the center, which indicates that the note is within acceptable range of the target pitch. Users can adjust the width of the green zone in the settings menu. The tuning meter also has a red zone on both sides, which indicates that the note is too sharp or too flat.
The Note Selector
The note selector allows users to select the note to be tuned by tapping on its name. Users can also swipe left or right to change octaves, or swipe up or down to change notes within an octave. The note selector also shows the temperament name and the stretch amount of the note. Users can edit the temperament and the stretch in the settings menu.
The Settings Menu
The settings menu allows users to customize various aspects of the app, such as tuning mode, temperament, stretch, reference pitch, green zone width, stop note, and more. Users can also save and load presets, import and export files, and access the manual and other information from this menu.
