Abstract: Aspects of the subject technology provide for automatic adaptive noise cancellation, which may be provided with a substantially flat frequency response. In one or more implementations, a noise cancellation signal is combined with a pass-through audio signal with a ratio that is controlled based on a mixing curve. The mixing curve may be one of multiple mixing curves that are defined for multiple respective operational states of an electronic device.
