a process which deliberately reduces the magnitude of certain spectral components of a signal with respect to the magnitudes of others, for instance in order to restore the original magnitude of the signal components increased by pre-emphasisoperation which consists in restoring the original amplitude/frequency characteristic of the recorded signal on reproduction
de-emphasis 1. A reduction in emphasis. 2. The act or process of de-emphasizing. 3. In electronics: a process of reducing the relative amplitude of certain frequencies in a signal that have been exaggerated by preemphasis, restoring the signal to its original form.
Filtering applied to an audio signal after storage or transmission to undo a linear distortion due to emphasis. See also: Emphasis.
