Use new advanced tuning and features, for example: Quickly detect the tuning reference pitch of a recording or performance to tune your instrument perfectly to that reference. Test advanced expert features included in Intonation Expert app.

Special Features:
- Harmonic Tuner
- Strobe Look (Up to 16 harmonics)
- Harmonic-wise tuning measurement (bargraphs, up to 16 harmonics)
- Harmonic-wise level measurement (bargraphs, up to 16 harmonics)
- Spectrum Tuner
- Reference Pitch (Concert A) & Key Detector

Trial features of Harmonic Tuner Intonation Expert*:
- Intonation (Tuning) & Inharmonicity protocol
- Temperament Detector

* 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.

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.

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.

They need to just put all of these into one app. The "full version" still has a bunch of limited features. Their excuse is that "the different features are all in separate apps for specific needs" but it's literally just so they can charge more for everything when they can just put it in one single app make it more convenient easier to use, it would literally be the best Turner utility on the Play store if they just put all the god damn things in one app.

Thank you for your opinion. If you even need complex expert features like unequal tunings, temperament detection and editing, please check Harmonic Tuner Intonation Expert. All the normal tuning features (Tuner, Strobe Look, Harmonics tuning, reference pitch detection ...) are available in the Full variant: for a significantly lower price.

Paying again for something I already bought! Seemed to be great at first though. We'll see what they have to say if anything.

Have installed all the modules but they do not "talk" to one another (android). Result is 5 modules and I have to pick the right ones which is hardly an integrated app! Recommend "Spectral Analysis of Musical Sounds: with emphasis on the Piano" by David M. Koenig for those interested in the desirability of such an approach, stretch tunings and the Railsback Curve etc.

The Harmonic Tuner apps don't connect but are standalone apps. Each app includes a set of modules & functionality, depending on your needs (the Intonation Expert variant allows for stretch tunings). From the available apps, please choose the one that has the modules you need. Please see the feature table (in Google Play, grainapps.com) to choose.
