eTuner overview

For those with instrumental talent, eTuner has also been developed and tested to work automatically with a variety of wind, brass, and string instruments.

eTuner is an interactive chromatic tuning application for Mac OS X. This application uses the quality audio and fine display capabilities of your Mac to determine and display musical pitch information as you play an instrument, hum, 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 or sing.

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.
  • 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 User Selectable Scale Key.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.
  • NEW! Support for transposed instruments.eTuner will display the "written note" for C, B♭, E♭, and F instruments. Select the transposition from the Instrument menu.
  • Calibration settings.The calibration setting provides the flexibility to adjust from the standard tuning of a'=440Hz.
  • Frequency and Octave DisplayThe frequency and octave number can be optionally displayed with the note name.
  • Input Level Meter and VolumeeTuner displays the current input device, channel, sample rate, and sound level. A slider control adjusts the input volume for the device. This allows the user to determine if they are producing a tone loud enough for eTuner to analyze.
  • Audio System PreferencesSelect input from any built-in microphone, or external audio device connected to your Mac.

Is this new? I cannot download and try this product? I cannot use the MacUpdate interface? Must I go to the app store? To this and other developers: while I love the Macintosh and have used Apple products since 1982, I find the App Store offensive and will not launch it. Frankly, it is one of the reasons that I use my aggregator and review the new stuff here, at MacUpdate, several times each week. I use many shareware products regularly. Any that are used are bought. Oh, about etuner. I am taking a singing course and thought that this might be useful (to someone like me who has a poor sense of pitch). I guess I will never know. But, I thought I should comment.
