Abstract:
A system that suppresses a plurality of interferences of different types in a received audio signal. The system comprises one or more microphones and an audio controller. The one or more microphones are configured to detect the audio signal. The audio controller applies an interference estimation algorithm to the audio signal to generate an attenuation coefficient for each of the plurality of interferences of different types. The audio controller applies the attenuation coefficients to the audio signal to generate an interference-suppressed audio signal in which the plurality of interferences of different types is suppressed. The audio controller determines a time domain signal based on the interference-suppressed audio signal to provide to an end user.
