Abstract: A computer having a system for mitigating mechanical rattle arising due to a mechanical coupling of an audio output transducer to a part of the computer device, the system comprising: a processing subsystem configured to receive an input audio signal and to output a drive signal for driving the audio output transducer to produce a transducer output, wherein the processing subsystem is configured to selectively apply an attenuation function to the input audio signal to attenuate a signal component of the input audio signal at a frequency that causes mechanical rattle in the computer; and an analyser subsystem configured to receive the input audio signal and to output a control signal to the processing subsystem to control application of the attenuation function to the input audio signal by the processing subsystem based on a spectral content of the received input audio signal; wherein the attenuation function is based on characteristic acoustic behaviour of the computer.

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.
