1. An electronic device comprising a circuitry configured to:
perform blind source separation based on a received input signal to obtain separated sources;
perform time-domain filtering on at least one of the separated sources to obtain at least one filtered separated source; and
perform remixing or upmixing based on the at least one filtered separated source,
wherein the circuitry is configured to perform the time-domain filtering by processing a window around a current sample and setting the current sample to zero if there is no sample in the window which has an amplitude that is larger or equal to a threshold value.
