Abstract
An electronic device comprising a circuitry configured to perform (402; 602; 902; 1002) blind source separation (201) based on a received input signal (1) to obtain separated sources; to perform (403; 605; 906; 1005) time-domain filtering (202) on at least one of the separated sources to obtain at least one filtered separated source; and to perform (404; 606; 907; 1006) remixing or upmixing (203) based on the at least one filtered separated source.
Claims19
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.
A method comprising:
- performing blind source separation based on a received input signal to obtain separated sources;
- performing time-domain filtering on at least one of the separated sources to obtain at least
- one filtered separated source;
- and
- performing remixing or upmixing based on the at least one filtered separated source,
- wherein the time-domain filtering is performed 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.
A non-transitory computer-readable medium storing a computer program comprising instructions that, when executed by a processor, cause the processor to perform a method comprising:
- performing blind source separation based on a received input signal to obtain separated sources;
- performing time-domain filtering on at least one of the separated sources to obtain at least one filtered separated source;
- and
- performing remixing or upmixing based on the at least one filtered separated source,
- wherein the time-domain filtering is performed 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.
