Problems solved by technology

For example, on the Android platform, due to the high delay of the application layer design (more than 100ms), if real-time input, real-time beautification and real-time output of sound are performed, the beautified and output sound will be significantly delayed compared to the user's singing voice

Abstract

Embodiments of the present invention provide a terminal sound processing method and terminal equipment. The method includes: acquiring an analog first sound signal; performing analog-to-digital conversion on the first sound signal to generate a digital second sound signal; Perform reverberation processing on the two sound signals to generate a digital third sound signal; perform digital mixing processing on the third sound signal and the background sound signal sent from the application layer to generate a digital fourth sound signal; perform digital mixing on the fourth sound signal digital-to-analog conversion to generate an analog fifth sound signal; perform analog mixing processing on the first sound signal and the fifth sound signal to generate an analog sixth sound signal; and play the sixth sound signal. The embodiment of the present invention can reduce the delay of the beautified sound by performing reverberation and beautification processing on the sound signal at the bottom layer of the system, realize real-time input, real-time beautification and real-time output of the sound, and improve user experience.

Description

technical field [0001] The present invention relates to the field of terminal equipment, and more particularly, to a sound processing method and terminal equipment. Background technique [0002] As mobile phone multimedia functions and applications become more and more abundant, karaoke applications are becoming more and more popular as emerging applications. This type of application mainly plays the accompaniment audio and video, and at the same time records the singer's voice through a microphone, and synthesizes it with the accompaniment after sound beautification. Typical applications include Karaoke Talent, Changba, etc. [0003] Karaoke technology has extremely high requirements for the delay of the recording and playback channel (the delay is less than 50ms), otherwise the human ear will feel that the beautified sound is delayed from the singing sound, and this delay is mainly introduced by the software platform. For example, on the Android platform, due to the high...
