Electronic device and method thereof for outputting audio data

A method for outputting audio data of an electronic device, the method comprising:

• generating first-mixed audio data by mixing at least one piece of second audio data;
• converting the first-mixed audio data into a designated format;
• generating second-mixed audio data by mixing at least one piece of first audio data and the first-mixed audio data converted into the designated format;
• post-processing the second-mixed audio data;
• and
• outputting the post-processed second-mixed audio data through at least one sound output device,
• wherein the generating the first-mixed audio data by mixing the at least one piece of second audio data comprises:
• determining whether the at least one piece of second audio data comprises a plurality of pieces of second audio data;
• and
• based on the determining that the at least one piece of second audio data comprises a plurality of pieces of second audio data, mixing the plurality of pieces of second audio data to generate the first-mixed audio data.

An electronic device comprising:

• an audio module configured to output, to at least one sound output device, at least one of at least one piece of first audio data having a designated format and at least one piece of second audio data having a format different from the designated format;
• at least one processor operatively connected to the audio module;
• and
• at least one memory operatively connected to the at least one processor and configured to store at least one instruction,
• wherein the at least one instruction, when executed by the at least one processor, causes the electronic device to:
• generate first-mixed audio data by mixing the at least one piece of second audio data;
• convert the first-mixed audio data into the designated format;
• generate second-mixed audio data by mixing the at least one piece of first audio data and the first-mixed audio data converted into the designated format;
• post-process the second-mixed audio data;
• transmit the post-processed second-mixed audio data to the audio module;
• and
• cause the audio module to output the post-processed second-mixed audio data through the at least one sound output device,
• wherein the at least one processor comprises a main processor and an audio signal processor,
• wherein the at least one instruction, when executed by the main processor, causes the main processor to transmit audio data having various formats to the audio signal processor, and
• wherein the at least one instruction, when executed by the audio signal processor, causes the audio signal processor to generate processed audio data by performing at least one of format conversion, mixing, and post-processing to be performed on at least a part of the audio data having various formats received from the main processor, and to transmit the processed audio data to the audio module.
