Abstract: Methods and apparatuses that provide a technical solution for handling a microphone operation request from more than one application is disclosed. The technical solution for processing data obtained by a microphone of a terminal device includes receiving an audio recording start command sent by a second application running on the terminal while the microphone is being used by a first application running on the terminal. The technical solution further includes assigning an unoccupied data receiving port to the second application, acquiring and broadcasting audio recording data collected by the microphone through a data sending port, receiving the audio recording data by the assigned data receiving port, and sending the audio recording data to the second application by the assigned data receiving port.

Abstract: The disclosure provides a noise reduction method and an electronic device. In an embodiment of the disclosure, when determining that a plurality of first applications occupy a plurality of first audio channels connected with a microphone and a second application occupies a second audio channel connected with a speaker, the electronic device resamples the audio data of the second audio channel according to the sampling rates corresponding to the plurality of first audio channels and then performs the noise reduction processing on the audio data of each of the plurality of first audio channels respectively according to the audio data obtained by resampling.

Abstract: A mobile device and method for controlling a speaker is provided. The method includes detecting when a calling surface of the mobile device changes from one surface to the other surface during a call, wherein the mobile device comprises a body, a first screen and a second screen, sound output holes arranged on both sides, and two speakers, where the first speaker faces the first sound output hole on the front surface, and the second speaker faces the second sound output hole on the back surface. The method further comprises enabling the second speaker facing the back surface, and disabling the first speaker facing the front surface if the calling surface changes from the front surface to the back surface; and enabling the first speaker facing the front surface, and disabling the second speaker facing the back surface if the calling surface doesn't change.
