Abstract
An audio processing circuit (106) includes at least one audio filter (110), at least one adaptive non-active noise control, non-ANC, filter (111), and a leakage detection circuit (112). The at least one audio filter (110) controls an output signal for an audio function. The at least one adaptive non-ANC filter (111) generates at least one non-anti-noise signal according to an audio playback signal. The leakage detection circuit (112) performs leakage detection according to a first input signal and a second input signal, and adjusts the at least one adaptive non-ANC filter (111) according to a leakage detection result, wherein the first input signal is indicative of noise signal signature, and the second input signal is derived from an error signal output by an error microphone (104) that picks up remnant noise resulting from the audio function.
