Problems solved by technology

However, the classic noise reduction algorithm is mainly based on the assumption that the noise is stationary. However, the application sound in many applications usually does not meet this assumption, resulting in poor suppression effect of the classic noise reduction algorithm.

Abstract

An application sound suppression method includes acquiring application sound data; acquiring ambient sound data collected by the microphone; performing an echo cancellation process on the ambient sound data according to the echo cancellation algorithm and the applied sound data. The application of sound data and its echoes is highly correlated, As a result, echo cancellation processing is performed on ambient sound data using an echo cancellation algorithm and sound data, The method can eliminate the echo of the applied sound data in the ambient sound data, has remarkable effect on the suppression of the applied sound, obviously improves the speech signal-to-noise ratio, can receive the pure speech signal at the receiving end, and improves the user experience. The present application alsodiscloses an application sound suppression apparatus, an apparatus and a storage medium.

Description

technical field [0001] The present application relates to the technical field of application development, and in particular to an application sound suppression method, device, computer storage medium and equipment. Background technique [0002] At present, many applications have audio playback and voice communication functions. When users communicate with each other, they are often disturbed by the audio signal played locally by the application, which affects normal voice communication. [0003] Taking game applications as an example, game players communicate with other players through voice communication in order to improve communication efficiency. It is collected by the microphone, resulting in a decrease in the speech signal-to-noise ratio, and in severe cases, it is difficult for the receiving end to distinguish the normal human voice of the sending end. [0004] In order to reduce the interference of the local sound of the application in the process of voice communica...
