    Abstract: An electronic device may include an audio output device; and a processor configured to be operatively connected to the audio output device. The processor is configured to: acquire a first user input for reproducing a first audio related to a first application; based on the first user input, generate first decoded data by decoding the first audio using a first codec; generate first synthesized data by applying a first audio effect to the first decoded data; transmit the first synthesized data to an audio framework; based on the first audio being decoded using the first codec, transmit, to the audio framework, a first request for deactivating a function of applying a second audio effect; and output the first synthesized data via the audio output device without applying the second audio effect to the first synthesized data, based on the function of applying the second audio effect being deactivated.

    Abstract: An electronic device that carries out communication and an operation method therefor are provided. The electronic device includes a short-range communication circuit and at least one processor operatively connected to the short-range communication circuit, wherein the at least one processor may be configured to establish a first communication connection to a first external electronic device via the short-range communication circuit, transmit, to a second external electronic device via the short-range communication circuit, first information associated with the first communication connection, if an event requiring a second communication connection between the second external electronic device and the first external electronic device occurs in the second external electronic device, receive, from the second external electronic device via the short-range communication circuit, second information notifying that the second communication connection will be established, and disestablish the first communication connection via the short-range communication circuit.

    Abstract: An electronic device according to various embodiments comprises a communication module including communication circuitry, at least one microphone, and a processor. The processor can be configured to: be connected to an external device through the communication module; switch a call audio signal path to an external device output path in response to being call-connected to an opponent device; duplicate a call audio signal (Rx in) transmitted from the opponent device, provide a first signal to an echo removal module, and provide a second signal to the external device via the external device output path; measure latency between the external device and the electronic device; variably adjust the size of a dynamic buffer for removing echo, by applying the measured latency; generate a reference signal delayed in the second signal, by the adjusted dynamic buffer; and remove an echo signal, with respect to the first signal generated from a speaker of the external device, from a microphone input signal obtained from the at least one microphone, based on the generated reference signal.
