n-Track Tuner

Tune your guitar, bass or other instrument with n-Track Tuner. Just put your iPhone, iPod Touch or iPad next to your instrument and play each string, the tuner will automatically recognize the note you're playing and tell you wether you need to lower (green bar) or increase (red bar) the string's pitch.

n-Track Tuner works great as a guitar tuner, violin, viola, violoncello, bass, piano and wind instruments tuner.

The spectrum analyzer provides a visual feedback of the notes played by the instrument and shows a small arrow to highlight the harmonic whose pitch the tuner is tracking.

For those who prefer to manually tune their instrument the 'Diapason' view lets you play a reference tone, 'A' (440 hz) or any other note that you can select dragging the frequency slider.

Advanced features
• adjust tuning sensitivity and precision up to 0.1 cents
• western and latin note namings, alternate temperaments
• calibrate the tuner for non-standard tunings: tune the reference note, tap on the display and select 'Calibrate' to set the note as the new reference
• 3D and 2D sonogram views (available as in-app purchases) lets you follow how the audio spectrum changes over time.
• adjust the spectrum analyzer visualization options, select thicker spectrum lines, smooth out or highlights peaks, increase or decrease spectrum accuracy etc.
