Abstract

Provided is a an electronic device and method of operating same. The electronic device includes: a wireless communication circuit configured to perform wireless communication with an external electronic device; an audio input device; at least one memory storing one or more instructions; and at least one processor operatively connected to the at least one memory and configured to execute the one or more instructions to: obtain first audio data through the audio input device, wherein the first audio data is synthetic data of a first signal received from a first talker and a second signal received from a second talker, and the first talker is closer to the electronic device than the second talker at the time the first audio data is obtained, receive second audio data from the external electronic device through the wireless communication circuit, wherein the second audio data is synthetic data of a third signal and a fourth signal, obtain a latency based on the first audio data and the second audio data, obtain compensated first audio data by compensating for the latency with respect to the second audio data, and obtain processed first audio data by removing the second signal from the compensated first audio data based on the third signal.

Claims (56)

1. An electronic device comprising:

a wireless communication circuit configured to perform wireless communication with an external electronic device;

an audio input device;

at least one memory storing one or more instructions; and

at least one processor operatively connected to the at least one memory and configured to execute the one or more instructions to:

obtain first audio data through the audio input device, wherein the first audio data is synthetic data of a first signal received from a first talker and a second signal received from a second talker, and the first talker is closer to the electronic device than the second talker at the time the first audio data is obtained,

receive second audio data from the external electronic device through the wireless communication circuit, wherein the second audio data is synthetic data of a third signal and a fourth signal,

obtain a latency based on the first audio data and the second audio data,

obtain compensated first audio data by compensating for the latency with respect to the second audio data, and

obtain processed first audio data by removing the second signal from the compensated first audio data based on the third signal.

2. The electronic device of claim 1 , wherein the at least one processor is further configured to execute the one or more instructions to:

obtain the processed first audio data by removing the second signal from the compensated first audio data via beamforming.

3. The electronic device of claim 1 , further comprising:

an audio output device,

wherein the at least one processor is further configured to execute the one or more instructions to:

output the processed first audio data via the audio output device.

4. The electronic device of claim 1 , wherein the at least one processor is further configured to execute the one or more instructions to:

transmit the processed first audio data to the external electronic device through the wireless communication circuit.

5. The electronic device of claim 4 , wherein the at least one processor is further configured to execute the one or more instructions to:

after transmitting the processed first audio data to the external electronic device, receive third audio data comprising the second audio data without the fourth signal, from the external electronic device through the wireless communication circuit.

6. The electronic device of claim 5 , further comprising:

a display,

wherein the at least one processor is further configured to execute the one or more instructions to:

display, on the display, a user interface corresponding to a function for mixing pieces of audio data; and

based on determining that a specified input on the user interface is sensed, generate synthetic data by mixing the processed first audio data and the third audio data.

7. The electronic device of claim 5 , wherein the a first frequency band of the third audio data is changed to a second frequency band through a bandwidth extension filter.

8. The electronic device of claim 1 , wherein the latency based on the first audio data and the second audio data comprises a system latency and an acoustic latency, and

wherein the at least one processor is further configured to execute the one or more instructions to:

obtain the system latency based on wireless communication between the electronic device and the external electronic device; and

obtain the acoustic latency based on a change in a location of the external electronic device relative to the electronic device.

9. The electronic device of claim 8 , wherein the at least one processor is further configured to execute the one or more instructions to:

identify a dominant frequency band of the first audio data and the second audio data.

10. The electronic device of claim 9 , wherein the at least one processor is further configured to execute the one or more instructions to:

obtain the acoustic latency based on the dominant frequency band based on a cross-correlation method.

11. A method of processing audio data using an electronic device, the method comprising:

obtaining first audio data through an audio input device of the electronic device, wherein the first audio data is synthetic data of a first signal received from a first talker and a second signal received from a second talker, and the first talker is closer to the electronic device than the second talker at the time the first audio data is obtained;

receiving second audio data from an external electronic device through a wireless communication circuit of the electronic device, wherein the second audio data is synthetic data of a third signal and a fourth signal;

obtaining a latency based on the first audio data and the second audio data;

obtain compensated first audio data by compensating for the latency with respect to the second audio data; and

obtaining processed first audio data removing the second signal from the compensated first audio data based on the third signal.

12. The method of claim 11 , wherein the obtaining the processed first audio data further comprises removing the second signal from the compensated first audio data via beamforming.

13. The method of claim 11 , further comprising:

outputting the processed first audio data via an audio output device of the electronic device.

14. The method of claim 11 , further comprising:

transmitting the processed first audio data to the external electronic device through the wireless communication circuit.

15. The method of claim 14 , further comprising:

after transmitting the processed first audio data to the external electronic device, receiving third audio data comprising the second audio data without the fourth signal, from the external electronic device through the wireless communication circuit.

16. The method of claim 15 , further comprising:

displaying, on a display of the electronic device, a user interface corresponding to a function for mixing pieces of audio data; and

based on determining that a specified input on the user interface is sensed, generating synthetic data by mixing the processed first audio data and the third audio data.

17. The method of claim 15 , a first frequency band of the third audio data is changed to a second frequency band through a bandwidth extension filter.

18. The method of claim 11 , wherein the calculating of the latency based on the first audio data and the second audio data comprises:

obtaining a system latency based on wireless communication between the electronic device and the external electronic device; and

obtaining an acoustic latency based on a change in a location of the external electronic device relative to the electronic device.
