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.
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.
Stretch Tunings and Temperaments:
Stretch tunings are common on pianos: instruments with plucked or hammered strings show slightly inharmonic overtones. Harmonic Tuner allows to widen octaves by 0 to 5 cent accordingly.
Historical keyboard music on organs, harpsichords etc. is typically performed using historic temperaments that provide individual consonance/dissonance characteristics for each key/scale. Harmonic Tuner Intonation Expert supports a set of popular historic temperaments you can tune your instrument to.
