Abstract
A method for reducing perceived audio distortion in a loudspeaker in response to an input audio signal may include attenuating the input audio signal within an attenuation frequency band of the input audio signal to generate a limited audio signal, generating masking audio to psychoacoustically mask absence of audio content attenuated from the attenuation frequency band of the input audio signal, and combining the limited audio signal and the masking audio to generate an output audio signal.
