Abstract
An audio refocusing method includes receiving an indication signal indicating which sound source in a recorded signal has to be refocused on; determining a direction of the sound source or a location of the sound source; and enhancing sound generated by the sound source in the recorded signal according to the direction or the location of the sound source to generate a processed signal.
Claims25
An electronic device, comprising:
- an interface, generating an indication signal indicating which sound source in a recorded signal has to be refocused on;
- a transmitting device, transmitting the indication to a processor;
- a receiving device, receiving a processed signal, wherein the processor enhances a sound generated by the sound source in the recorded signal to generate the processed signal;
- and
- a play device, playing the recorded signal and/or the processed signal,
- wherein the recorded signal is a multimedia signal comprising an image portion and an audio portion,
- wherein the generation of the processed signal includes refocusing the audio portion of the sound source in the multimedia signal without referring to refocus result of the image portion of the sound source.
