Abstract
(EN) An audio processing method. The audio processing method comprises: acquiring an audio signal to be processed, wherein said audio signal comprises audio components having different frequencies (S101); determining a sound source direction corresponding to each audio component (S102); adjusting the gains of the audio components on the basis of the degree of matching between the sound source direction and a target direction (S103); and synthesizing a target audio signal on the basis of the gain-adjusted audio components (S104). By means of the audio processing method, directional sound pickup in any direction is realized.
(FR) Procédé de traitement audio. Le procédé de traitement audio comprend : l'acquisition d'un signal audio à traiter, ledit signal audio comprenant des composantes audio ayant des fréquences différentes (S101) ; la détermination d'une direction de source sonore correspondant à chaque composante audio (S102) ; le réglage des gains des composantes audio sur la base du degré de correspondance entre la direction de source sonore et une direction cible (S103) ; et la synthèse d'un signal audio cible sur la base des composantes audio à gains réglés (S104). Au moyen du procédé de traitement audio, une capture de son directionnelle dans n'importe quelle direction est réalisée.
(ZH) 一种音频处理方法,包括:获取待处理音频信号,该待处理音频信号包括不同频率的音频分量(S101);确定每个音频分量对应的声源方向(S102);基于声源方向与目标方向的匹配度,调整音频分量的增益(S103);基于调整增益后的音频分量合成目标音频信号(S104)。该音频处理方法实现了任意方向的指向性拾音。
