Abstract
(EN)
Embodiments of the present invention provide a method and a device for processing audio in video communication. The method comprises: acquiring audio data in video communication and audio source position information corresponding to the audio data; and performing longitudinal-depth processing on the audio data according to the audio source position information. In the embodiments of the present invention, audio data in video communication and audio source position information corresponding to the audio data are acquired first, and then longitudinal-depth processing is performed on the audio data according to the acquired audio source position information, to enable the audio data to have a longitudinal depth matching the audio source position information, so that sounds generated by objects at different longitudinal positions in video communication can be distinguished.

Les modes de réalisation de la présente invention concernent un procédé et un dispositif de traitement audio dans une communication vidéo. Le procédé consiste à : acquérir des données audio dans une communication vidéo et des informations de position de source audio correspondant aux données audio ; et effectuer un traitement de profondeur longitudinale sur ​​les données audio selon les informations de position de source audio. Dans les modes de réalisation de la présente invention, les données audio dans la communication vidéo et les informations de position de source audio correspondant aux données audio sont acquises en premier, et ensuite, le traitement de profondeur longitudinale est effectué sur les données audio selon les informations de position de source audio acquises, afin de permettre aux données audio d'avoir une profondeur longitudinale correspondant aux informations de position de source audio, de sorte que les sons générés par des objets à différentes positions longitudinales dans la communication vidéo puissent être distingués.
