Title

(EN) METHOD AND APPARATUS FOR ACQUIRING AND PROCESSING MULTIPLE AUDIO SIGNALS, AND CONFERENCE DEVICE

(FR) PROCÉDÉ ET APPAREIL D'ACQUISITION ET DE TRAITEMENT DE MULTIPLES SIGNAUX AUDIO ET DISPOSITIF DE CONFÉRENCE

(ZH) 多路音频信号采集与处理方法、装置以及会议设备

Abstract

(EN) Embodiments of the present application disclose a method and apparatus for acquiring and processing multiple audio signals, and a conference device. In the embodiments of the present application, an independent connection link and an independent audio acquisition link are provided for each audio input device, so that an application program can acquire a first audio signal from each first audio acquisition link by means of a corresponding first API interface of an operating system, and separately process the acquired first audio signal. The embodiments of the present application can separately acquire multiple audio signals, so that the application program can flexibly process each acquired audio signal, thereby satisfying requirements in different conference scenarios, and solving the technical problem in the prior art that a conference device cannot separately acquire each audio signal when simultaneously acquiring multiple audio signals.

(FR) Des modes de réalisation de la présente demande divulguent un procédé et un appareil d'acquisition et de traitement de multiples signaux audio et un dispositif de conférence. Dans les modes de réalisation de la présente demande, une liaison de connexion indépendante et une liaison d'acquisition audio indépendante sont fournies pour chaque dispositif d'entrée audio, de telle sorte qu'un programme d'application peut acquérir un premier signal audio à partir de chaque première liaison d'acquisition audio au moyen d'une première interface API correspondante d'un système d'exploitation et traiter séparément le premier signal audio acquis. Les modes de réalisation de la présente demande peuvent acquérir séparément de multiples signaux audio, de telle sorte que le programme d'application peut traiter de manière flexible chaque signal audio acquis, satisfaisant ainsi les exigences dans différents scénarios de conférence et résolvant le problème technique de l'état de l'art selon lequel un dispositif de conférence ne peut pas acquérir séparément chaque signal audio lors de l'acquisition simultanée de multiples signaux audio.

(ZH) 本申请实施例公开了一种多路音频信号采集与处理方法、装置以及会议设备，本申请实施例通过为每个音频输入设备提供了独立的连接链路以及音频采集链路，使得应用程序能够通过操作系统的第一API接口从每条第一音频采集链路中采集第一音频信号，并对采集到的第一音频信号单独进行处理。本申请实施例能够实现多路音频信号的单独采集，使得应用程序能够灵活对每一路采集到的音频信号进行处理，能够支持不同会议场景下的需求，解决了现有技术中会议设备在同时进行多路音频信号采集的情况下，无法单独采集每一路音频信号的技术问题。
