Abstract: An electronic device includes: an Application Processor (AP) including a CPU; and an audio processing unit configured to: receive an audio stream of M channels from the CPU, convert the M-channel audio stream into an N-channel audio stream, the N-channel being different from the M-channel, output the N-channel audio stream through an output device. The audio processing unit is further configured to: detect a connection with the external electronic device through an audio output interface; determine whether to stop the converting the M-channel audio stream into the N-channel audio stream, based on information received from the CPU; and transmit, via the audio output interface, the M-channel audio stream to the external electronic device in response to the determination of stopping the converting the M-channel audio stream into the N-channel audio stream.

Abstract: An electronic device and method are disclosed. The electronic device includes an internal microphone, a communication module, and at least one processor. The processor implements the method, including: receiving, through the communication module, a first audio signal input through an external microphone included in an external electronic device communicatively connected to the electronic device, activating the internal microphone in response to detecting a device switch event switching from the external microphone to the internal microphone while receiving the first audio signal, receiving a second audio signal input through the internal microphone, synchronizing and mixing the first audio signal and the second audio signal during a designated first time period, and deactivating the external microphone upon detecting lapse of the designated first time period.
