Lingot – musical instrument tuner

LINGOT Is Not a Guitar-Only Tuner (Lingot) is an open source musical instrument tuner. It is accurate, easy to use, and highly configurable. Originally conceived to tune electric guitars, it can now be used to tune any instrument.

Lingot looks like an analogic tuner, with a gauge indicating the relative shift to a certain note indicating that note and its frequency.

The default values are optimized for electric guitar tuning, for other musical instruments these values must be slightly changed (a good practice would be to have a configuration file for each instrument).

Features include

  • Highly configurable graphical user interface. Change any parameter while the program is running, without editing any file.
  • Adjustments:
    • Calculation rate.
    • Visualization rate.
    • Noise threshold.
    • Gain.
  • Basic Adjustments:
    • Effective sample rate.
    • FFT size.
    • Temporal window.
    • Minimum frequency.
  • Advanced options:
    • DFT number.
    • DFT size.
    • Peak number.
    • Peak half-width.
    • Peak rejection relation.
  • Quick and accurate, perfect for real-time microtonal tuning.
  • Easy to use. Just plug in your instrument and run it.
  • Universal tuner. It can tune many musical instruments, you only need to provide the temperaments. For that purpose, it supports the Scala project .scl format.
  • Wide range of options.
  • Graph showing the spectral power density of the captured signal. The fundamental frequency is shown with a red dot, and the noise threshold with a horizontal dotted yellow line.
