Compare string sets with Harmonic Tuner Intonation Expert for Android – Worn (left) vs. fresh (right) guitar strings – strong effect on intonation, tuning and adjustability
The two tuning protocols show the high E string (0.010″) of an electric guitar and the tuning at each fret. The worn string (left) leads to significantly lowered notes at middle frets an too high notes at higher frets, this string can not be set up for proper intonation. The fresh string on the same guitar and bridge setup gives nearly perfect intonation.
With Sustain Analyzer’s protocol features your can quickly visualize how sustain changes along an instrument’s note range,
for example to detect dead spots and wolf notes. With the overlay features you can quickly compare the sustain behaviour of different instruments: sustain protocols can be easily compared, stored and exported as text value lists.
Sustain protocol of an electric guitar’s low E string – each note is shown with its overall sustain value and the individual values of the first 4 harmonics:
Sustain protocols of low and high E strings of an electric guitar compared using Sustain Analyzer’s overlay functions:
Sustain Analyzer estimates how fast the harmonics levels of a note decrease over time.
The level and sustain envelopes of a note’s harmonics define its timbre.
The app shows amplitude graphs of each measured harmonic and its sustain as dB/s metric and decay time (seconds, T60).
Alternatively the app can display the harmonics’ sustain as bargraphs (dB/s).

Intonation Expert offers a tool to recognize typical temperaments mainly from polyphonic solo keyboard performances / recordings. Like the Reference Pitch detector, the Temperament Detector performs a long time analysis of the audio signal. Tuning Spectrums for each note are displayed in a Temperament Spectrum diagram and compared with the internal Temperament database to get a best-fit Temperament suggestion.

A piece played at Werckmeister tuning at A=442 Hz while it is analyzed in Temperament Editor:
Inspect the factory temperament presets, modify them or enter / create your own temperament presets with Temperament editor.
Temperaments can be compared with a useful diagram overlay function.
The harmonic consonance/dissonance behaviour of a temperament’s chords is displayed as deviation from perfect intervals (fifth, thirds).
Use your reference instrument measurement created with Intonation Protocol to fine and store as a preset with Temperament editor.
Find similar temperaments to the temperament you are editing using Temperament Editor’s statistics/comparison functions.

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. Use the Inharmonicity protocol module to check the inharmonicity range of your strings, than set the stretch tuning 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. The root note of each temperament scale can be transposed. The amount of the temperament can be scaled from 5% to 100%
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 protocols are useful for checking and setting up guitar/bass intonation, for measuring pipe organs or to measure the intonation and tuning stretch of an instrument. Sets of measurements can be compared and stored. The raw protocol data can be exported as a table via text clipboard.

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.

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 for up to 16 harmonics.
Youtube Demo Clip (Example Bargraph harmonic tuning and level displays & electric guitar)
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.
