Abstract
A device for processing an audio signal arising from a radiofrequency signal, including: an instantaneous multipath sensor able to analyze the radiofrequency signal so as to determine an instantaneous multipath rate, an instantaneous filter block able to attenuate the audio signal in line with an instantaneous attenuation that is an increasing function of the instantaneous multipath rate, also including a mean multipath sensor able to determine a mean multipath rate, and a mean filter block able to attenuate the audio signal in line with a mean attenuation that is an increasing function of the mean multipath rate. A radio receiver having such a processing device is also disclosed.
