WebWhat is tonality? Tonality is a measure of sound quality that correlates to how humans perceive the tonal components of sound. The tonality analysis identifies and measures tones in a certain noise spectrum. In acoustics, tonality is a subject of psychoacoustics, which studies the correlation between acoustical stimuli and hearing sensations. WebThe tonality metric of this standard uses the auto-correlation function to describe causes of perceived tonality such as individual or multiple steady or time-varying discrete tones, individual or multiple spectrally elevated bands or slopes of noise, and combinations of these phenomena.
