WebSpectral flatness or tonality coefficient, also known as Wiener entropy, is a measure used in digital signal processing to characterize an audio spectrum. Spectral flatness is typically measured in decibels , and provides a way to quantify how much a sound resembles a pure tone , as opposed to being noise -like.
