HarmonicTune 0.93

General purpose chromatic Instrument Tuner
The HarmonicTune application was designed to be an general purpose chromatic Instrument Tuner. You should be able to tune nearly every kind of instrument with it (including brass, strings, piano, guitars...).

Nevertheless the algorithm for the base frequency detection is not perfect, but I hope to improve it step by step over time. The application is written in C++, uses the libraries "wxWidgets" and "portaudio" and is compiled and organized with the great free IDE "Code::Blocks" using MinGW.

NOTE: only for private, non-commercial use.

Main features:

  • Universal automatic tone detection for nearly all kind of instruments
  • Theoretical tuning range from C0 ... B7
  • Samplingrate, FFT size and threshold level adjustable
  • Following fundamental frequency detections algorithms are available:
  • Power Density Spectrum
  • Cepstrum
  • The algorithm parameters are adjustable
  • The tuning basis is adjustable
  • Following temperaments possible:
  • Equal Temperament
  • Just Intonation
  • Meantone Temperament
