Coherence Tuner 1.1

This application employs an innovative tuning engine capable of detecting and measuring the pitch of multiple notes simultaneously.

The built-in microphone facilitates a high degree of accuracy, comparable to that of traditional strobe tuners.

Users will find it quick and straightforward; it operates in a fully polyphonic mode. Simply launch the app and either strum or pluck individual strings for an immediate reading.

Features such as automatic gain control and noise elimination enhance its usability, while a few customizable settings ensure it retains a plug-and-play simplicity.

The advanced multi-mode display presents tuning information for all strings concurrently in a clear and straightforward manner.

Operating over a wide frequency range, the tuning engine incorporates a simple indicator for standard tuning alongside a highly precise wave tuning overlay, delivering pitch accuracy equivalent to leading strobe tuners.

In addition to standard 6-string guitar tuning, it supports various alternate tunings, including:

• E Flat
• D
• Drop D
• Double Drop D
• DADGAD
• Open D
• Open E
• Open G

Future updates are anticipated, potentially expanding the range of available tunings.

Additional instrument compatibility includes:

• 7-String Guitar
• Violin
• Viola
• Cello
• 4-String Bass
• 5-String Bass
• 6-String Bass
• Ukulele
• 5-String Banjo

The tuner allows users to select a reference frequency ranging from 435Hz to 445Hz, with 440Hz set as the default.

Moreover, the engine can be configured to tune using either the string fundamental or its second harmonic, thereby maximizing compatibility across various instruments and frequency ranges. Although tuning with the fundamental is generally recommended for enhanced accuracy, there are cases where utilizing the second harmonic may be beneficial, particularly for instruments in the bass spectrum.

The application functions intuitively: pluck strings on your instrument to see coarse tuning indicated by responsive needles. As you approach the desired pitch, a wave overlay appears and shifts left or right based on your pitch. When pitch is precisely achieved, the wave stabilizes.
