eTuner for iOS Available on the iTunes App Store

eTuner is an interactive chromatic tuning application for iPhone and iPad. This application utilizes the quality audio and fine display capabilities of your device to determine and display musical pitch information as you play an instrument or sing a note.

In addition to instrument tuning, eTuner can also be used for scale studies and checking intonation as you play an instrument. eTuner has been developed and tested to work automatically with a variety of wind, brass, string instruments, and voice. Other instruments that produce a sustained tone will also work acceptably.

eTuner features:

• Graphical note display

eTuner displays the name of the note that is closest to pitch being detected as well as the amount of variance between the detected pitch and the displayed note, relative to the next higher or lower pitch. Also displayed is an indication of whether the pitch is High, Low, or OK, in relation to the note name being displayed. Frequency and octave number are optionally displayed. The picture to the right shows eTuner detecting a pitch that is 25% above A♭.

• Simple, easy to read display.

The note display has been designed for easy interpretation when appearing anywhere within the musician's field of vision. eTuner allows the musician's focus to remain primarily on the music stand, while reinforcing interpretation of peripheral vision cues.

• Chromatic Tuning with Scale Key settings

eTuner displays all twelve pitches in an octave. The key settings feature allows the user to select which note names will be displayed when pitches of the selected key are detected. Selecting a minor key will also display note names for the harmonic and melodic ascending and descending scales. Notes that are not in the selected key are displayed as what is customary in the chromatic scale.

• Heads up preferences display

Simply tap the screen once to show the eTuner toolbar. Select the info "i" buton on the main toolbar to view extended preferences. Extended preferences include optional frequency and octave number display, Transposed Instrument key, and also a setting to disable device Auto-Lock.

• Support for transposed instruments.

eTuner will display the "written note" for C, D, A, G, B♭, E♭, and F instruments. Select the transposition from the extended preferences view.

• Calibration settings

eTuner is a highly accurate tuning application that utilizes the audio hardware of your system which by itself needs no calibration. The calibration setting provides the flexibility to adjust from the standard tuning of a'=440Hz.

• Frequency and Octave Display

The frequency and octave number can be optionally displayed with the note name.
