Full description
Get 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. Test new 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 version of Harmonic Tuner Suite offer functionality of Full Version but are restricted to a limited usage time per start of the app. Features of Intonation Expert are available in trial versions with a limited number of protocol notes. See Harmonic Tuner Website 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 tool for musicians and sound engineers. Its special 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 version 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 similar appearance of moving patterns. While typical mechanical strobe tuners show 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 several 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 popular 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 tool to recognize typical temperaments mainly from polyphonic solo keyboard performances / recordings.
