Abstract: A method and a system for intelligent dynamic speech enhancement for an audio source, comprising performing speech detection and intelligent enhancement gain control on a multi-channel audio source input to determine speech enhancement gain, and further comprising applying the speech enhancement gain in dynamic loudness balancing performed on the multi-channel audio source input, wherein the intelligent enhancement gain control comprises setting the speech enhancement gain based on a signal power strength ratio of a signal of a center channel to a sum of signals of other channels, and setting the speech enhancement gain based on a system volume level

Abstract: Method for acquiring seismic data is described. The method includes obtaining undersampled seismic data acquired from a non-uniform sampling grid. Attenuating multiples from the undersampled seismic data.

Abstract: This application discloses a method for selecting an ability of a virtual object in a virtual battle performed by a computer device. The method includes: displaying a first ability identifier of a first ability, the first ability being an ability configured for the virtual object to perform the first ability at a first level in a virtual battle; displaying at least two second ability identifiers of at least second abilities associated with the virtual object in response to the virtual object changing from the first level to a second level in the virtual battle, the second abilities corresponding to the second level, and the at least two second ability identifiers comprising a target second ability identifier; receiving a selection operation on the target second ability identifier; and replacing the first ability with a second ability according to the selection operation.

Abstract: An earphone and a mobile terminal is provided, in which the earphone includes a housing and a speaker assembly. The housing internally includes a front cavity and a rear cavity that are separated by the speaker assembly. The front cavity is located on a side that is of the speaker assembly and that is a sound output direction, and the rear cavity is located on an opposite side of the sound output direction of the speaker assembly. One or more sound guide channels are disposed in the housing, each sound guide channel is disposed in a sidewall of the housing, and each sound guide channel is configured to: when the earphone is normally worn, connect air inside an ear canal of a user to air outside the ear canal without connecting air in the front cavity to air in the rear cavity.
