About the application:

Receive very accurate instrument tuning based on harmonic measurements and precise spectral analysis. Quickly detect the tuning reference pitch of a recording or performance to tune your instrument perfectly to that reference piece. Try fresh advanced tuning and intonation features for free. Special Features: - Harmonic Tuner - Spectrum Tuner - Reference Pitch (Concert A) & Key Detector Limited Features (Trial)*: - Strobe Look (Up to 16 harmonics) - Harmonic-wise tuning measurement (bargraphs, up to 16 harmonics) - Harmonic-wise level measurement (bargraphs, up to 16 harmonics) Trial features of Harmonic Tuner Intonation Expert*: - Intonation (Tuning) & Inharmonicity protocol - Temperament Detector * The trial features in non-Full ver of Harmonic Tuner Suite offer functionality of Full Ver but are restricted to a limited usage time per begin of the app. Features of Intonation Expert are accessible in trial versions with a limited number of protocol notes. See Harmonic Tuner Site for a table of Harmonic Tuner's versions and their features and more details. http://harmonictuner.grainapps.com Feature Details: Harmonic Tuner: Harmonic Tuner is a novel accurate instrument tuning program for musicians and sound engineers. Its unique feature is to perform pitch measurements (0.1 cents precision) by analysing tuning and levels of up to 16 individual overtones (harmonics) of a note. Harmonic Tuner is based on an accuracy-refined spectral analysis algorithm. Visualization is optimized for readability. Concert A pitch ranges from 320Hz to 604Hz (+/-5 semitones, precision 0.5 c, ca. 0.1 Hz). Intonation Expert ver supports stretch tunings and historical temperaments (Werckmeister etc.). Strobe Look: Harmonic components especially at stringed instruments like guitars, basses,pianos are always detuned. Up to 16 note's harmonics can be displayed individually in an intuitive and precise strobe tuner look of adjustable sensitivity. Harmonic Tuner Strobe Look does not implement the conventional strobe tuner principle, but offers a related appearance of moving patterns. While typical mechanical strobe tuners present detuning of octave harmonics only, Harmonic Tuner Strobe Look shows the detuning even of non-octave harmonics. Tuning + Level bargraphs for each harmonic (up to 16 harmonics): Overtone detuning of strings affects the timbre of a note as the levels and envelopes of the note's harmonics do. To inspect these trimbral characteristics, the detuning and the relative levels are displayed in bar graphs. Spectrum Tuner: A novel feature of Harmonic Tuner is the Spectrum Tuner. It visualizes the sounds in an intuitive real-time Detuning Spectrum. Even polyphonic sounds (chords) can be quickly checked for being in or out of tune. Reference Pitch (Concert A) Detector & Key Detector: The novel Reference Pitch Detector module finds the tuning reference frequency of musical performances or recordings accurately. In addition, the prominence of all 12 notes over a few seconds is displayed and the fitting Major/minor scale is estimated. Intonation (Tuning) & Inharmonicity protocols: For precise assessment of an instrument's intonation, stretch tuning, temperament etc., tuning/inharmonicity of a whole series of notes is recorded and displayed in a diagram. When measuring keyboard with historic tunings, a Temperament detection recognizes the best-fitting out of a number of famous historic temperaments. The intonation protocol is useful for checking and setting up guitar/bass intonation or to measure the tuning stretch of an instrument. Temperament Detector: Intonation Expert offers a program to recognize typical temperaments mainly from polyphonic solo keyboard performances / recordings.
