Intonation Expert – Temperament Detector

15/03/2018 by Grain Apps

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.

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.
