Abstract: Embodiments of this application provide a sound signal processing method and an electronic device, which can reduce an interference sound signal in a sound during video recording and improve quality of a sound signal during the video recording. The method is applied to an electronic device. The method includes: acquiring, by the electronic device, a first sound signal; the first sound signal being a sound signal during video recording; processing, by the electronic device, the first sound signal to obtain a second sound signal; and outputting, by the electronic device, the second sound signal when playing back a recorded video file. Energy of a sound signal in the second sound signal in a non-target orientation is lower than energy of a sound signal in the first sound signal in the non-target orientation. The non-target orientation is an orientation outside a field of view range of a camera during video recording.

Abstract: This application provides a video processing method and a related electronic device. The video processing method includes: When generating a video, the electronic device may perform image zooming based on a change in a zoom ratio, or may perform audio zooming on an audio based on a change in a zoom ratio. That the electronic device performs audio zooming on the audio includes: When the zoom ratio increases and an angle of view decreases, suppressing a sound of an object outside a photographing range and enhancing a sound of a photographed object within the photographing range; when the zoom ratio decreases and the angle of view increases, suppressing a sound of an object outside the photographing range and weakening a sound of a photographed object within the photographing range.

Abstract: A voice processing method is provided. The method includes: An electronic device first performs de-reverberation processing on a first frequency domain signal to obtain a second frequency domain signal, performs noise reduction processing on the first frequency domain signal to obtain a third frequency domain signal, and then performs, based on a first voice feature of the second frequency domain signal and a second voice feature of the third frequency domain signal, fusion processing on the second frequency domain signal and the third frequency domain signal that belong to a same channel of first frequency domain signal, to obtain a fused frequency domain signal. In this case, background noise in the fused frequency domain signal is not damaged, thereby effectively ensuring stable background noise of a voice signal obtained after voice processing. In addition, an electronic device, a chip system, and a computer-readable storage medium are provided.
