Tuner

Advanced Pitch Detection & Accuracy

• Combines autocorrelation algorithms and Fast Fourier Transform (FFT) spectral analysis for highly responsive, real-time frequency detection.

• Enhances tuning precision beyond standard algorithms by evaluating spectral phase information and applying polynomial fitting to interpolate exact frequencies.

• Displays a visual timeline showing how the detected pitch changes over time, helping users analyze instrument stability and sustain.

Instrument & Tuning Library

• Features a built-in library of common instruments and presets, including chromatic tuning, acoustic/electric guitar, bass, violin, and other orchestral strings.

• Supports custom instrument profiles, allowing musicians to define and save personalized tuning configurations.

Historical & Microtonal Temperaments

• Supports traditional and historical tuning systems, including Equal Temperament, Just Intonation, Werckmeister, and Kirnberger.

• Accommodates microtonal music exploration with support for non-12-tone Equal Divisions of the Octave, including 17, 19, 41, and 53 EDO.

Scientific & Technical Customization

• Provides granular control over digital signal processing settings, including adjustable FFT window size and overlap parameters.

• Allows selection of different FFT window types to optimize spectral resolution and minimize frequency leakage based on user needs.

Open Source & Community Support

• Available as a fully open-source application, with the source code accessible on GitHub: https://github.com/thetwom/Tuner

• Allows users and developers to submit feature requests or report bugs via the official issue tracker: https://github.com/thetwom/Tuner/issues

FAQ

Q: Does this tuner provide any visual feedback to help me understand my instrument’s performance over time?

A: Yes, it includes a unique visual timeline that displays how a detected pitch fluctuates while you play. This is particularly useful for musicians who want to analyze the stability of their instrument or observe how the pitch shifts during long, sustained notes.

Q: Which instruments are included in the built-in tuning library?

A: The application comes pre-loaded with a comprehensive library for common instruments, including acoustic and electric guitars, bass, violin, and various other orchestral strings. It also includes a standard chromatic tuning mode, making it versatile enough for almost any musical context.

Q: Can I save my own unique tuning configurations for specific instruments?

A: Absolutely, as the software fully supports custom instrument profiles. This allows you to define and save personalized tuning configurations, making it easy to switch between different setups or experimental tunings without having to manually recalibrate your settings every time.
