Abstract: A method includes displaying, on a display interface of a terminal, duration of a to-be-edited audio file; and displaying, on the display interface of the terminal, lyrics that are of the to-be-edited audio file and that correspond to a preset editing duration. The method further includes adjusting the editing duration according to at least one of a start moment or an end moment entered by a user; and displaying, on the display interface of the terminal, lyrics corresponding to the adjusted editing duration, for the user to determine audio file content corresponding to the editing duration. The method additionally includes acquiring an audio file corresponding to editing duration that is between the start moment and the end moment, in response to the user determining a start moment and an end moment for final editing.

Abstract: A method and an apparatus for managing a notification bar message relate to the field of electronic device applications and resolve a problem of a tedious operation for clearing a resident notification message. The method includes: searching for a resident notification message; after the resident notification message is found, displaying, in a notification bar, prompt information prompting whether to delete the resident notification message; and if a user chooses to delete the resident notification message, deleting the resident notification message according to a system permission. The method and apparatus are mainly applied to a process of managing a mobile phone application.

Abstract: A method and an apparatus for clearing a malicious power-consuming application, and a user terminal are provided. An application whose background working power consumption is not less than a power consumption threshold is determined as a malicious power-consuming application; and a wakelock occupying time of each application if a screen is turned off is periodically calculated, and if a background working application's wakelock occupying time is not less than a set time threshold, the application is determined as a malicious power-consuming application.

Abstract: A method is provided for Voice over Internet Protocol (VoIP) devices to communicate over an Internet Protocol (IP) network. The method includes synchronizing the VoIP devices using one or more dual-tone multi-frequency (DTMF) codes over a telephone network, retransmissions of voice packets in bursts, retransmissions of voice packets following a time lag, adjusting the number of retransmissions based on quality of service, retransmission of a missing voice packet identified in a list received from a peer device, discarding low energy voice frames in a jitter buffer to prevent overflow, stopping playout at a low energy voice frame when the jitter buffer is below a minimum buffer size, and selective transmission and retransmission of voice packets based on their energy levels.
