Electronic device for generating or playing back audio signal, and operating method thereof

A method performed by an electronic device, the method comprising:

• receiving, by the electronic device, two or more pieces of audio data simultaneously acquired by one or more external electronic devices;
• identifying, by the electronic device, user individual head-related transfer function (HRTF) information acquired based on reference HRTF information by using user information;
• based on the two or more pieces of audio data, identifying, by the electronic device, sound source generation location information of the two or more pieces of audio data;
• generating, by the electronic device, an audio signal by performing inverse filtering of the two or more pieces of audio data, based on the user individual HRTF information;
• and
• transmitting, by the electronic device, the audio signal and the sound source generation location information to another electronic device.

An electronic device comprising:

• a communication circuit;
• memory, comprising one or more storage media, storing instructions;
• and
• one or more processors communicatively coupled to the communication circuit and the memory,
• wherein the instructions, when executed by the one or more processors individually or collectively, cause the electronic device to:
• receive, through the communication circuit, a binaural audio signal and sound source generation location information of the binaural audio signal from another electronic device,
• identify user individual head-related transfer function (HRTF) information acquired based on reference HRTF information by using user information acquired from the memory,
• generate two pieces of audio data by applying the user individual HRTF information and the sound source generation location information to the binaural audio signal, and
• transmit the two pieces of audio data to one or more external electronic devices so as to reproduce the two pieces of audio data by the one or more external electronic devices.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform operations, the operations comprising:

• receiving, by the electronic device, two or more pieces of audio data simultaneously acquired by one or more external electronic devices;
• identifying, by the electronic device, user individual head-related transfer function (HRTF) information acquired based on reference HRTF information by using user information;
• based on the two or more pieces of audio data, identifying, by the electronic device, sound source generation location information of the two or more pieces of audio data;
• generating, by the electronic device, an audio signal by performing inverse filtering of the two or more pieces of audio data, based on the user individual HRTF information;
• and
• transmitting, by the electronic device, the audio signal and the sound source generation location information to another electronic device.
