Abstract: An electronic device for processing an audio signal is provided. The electronic device includes a communication circuit, a microphone, a connector and a processor. The processor identifies whether the external cable connected with a first external electronic device and including a resistor having a resistance value equal to or greater than a designated resistance value is connected to the connector, and in response to identifying that the external cable is connected to the connector, transmit a first audio signal to the first external electronic device through the external cable, and receive a second audio signal including an echo signal and a voice signal through the microphone, and cancel the echo signal corresponding to the first audio signal, based at least partly on a delay time corresponding to the external cable and a parameter related with a filter corresponding to the external cable.

Abstract: An electronic device and an operating method thereof for identifying a noise control parameter on the basis of network connection information are provided. The electronic device includes a wireless communication circuit, and a processor. The processor is configured to acquire network connection information of an external electronic device which is call connected, through the wireless communication circuit, identify at least one noise control parameter, on the basis of the acquired network connection information, receive an audio signal from the external electronic device, through the wireless communication circuit, and suppress a noise in the audio signal, on the basis of the identified at least one noise control parameter.
