Abstract
Uses of an enhanced sidetone signal in an active noise cancellation operation are disclosed. In one example, a method of audio signal processing includes producing an anti-noise signal based on information from a first audio signal. A target component of a second audio signal is separated from a noise component of the second audio signal to produce at least one among a separated target component and a separated noise component. Based on at least one among the separated target component and the separated noise component, an audio output signal is produced.
