Claim Text:
1. An audio signal processing system, comprising: an input for receiving at least an audio signal which has been wirelessly transmitted; a time domain to frequency domain converter; an extraction unit configured to extract magnitude and phase spectra having extracted magnitude components and extracted phase components; a processor configured to process the extracted magnitude components based on an indication of multipath interference; a combiner configured to combine the processed magnitude components and the phase spectrum to derive a frequency domain output; and a frequency domain to time domain converter; wherein the processor is configured to receive a detector signal indicating a level of multipath interference, and is configured to process the extracted magnitude components in dependence on the level of multipath interference; and wherein the processor comprises a mixer configured to mix the extracted magnitude components and the processed magnitude components with a mixing ratio which is dependent on the detector signal.
