Harmonics to noise ratio (HNR) and harmonics to fundamental ration (HFR) are calculated using a proprietary high-performance zero-cross point detection algorithm. is calculated and visualized.
We have released two modes: a mode that continuously plots two indexes related to noise and overtones on a two-dimensional coordinate axis, and a graph display of time-series changes in voice pitch and harmonic energy.
In a quiet environment, the fundamental frequency can also be calculated with high accuracy. Please use it for voice training and singing training.
