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.

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.
