Intonation Expert – Temperament Detector

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.
