Title (EN) AUDIO INFORMATION PROCESSING METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE TRAITEMENT D'INFORMATIONS AUDIO
(ZH) 音频信息处理方法及装置
Abstract:
(EN) An audio information processing method and device. The audio information processing method comprises: decoding an audio file to acquire a first audio sub-file corresponding to a first audio channel output and a second audio sub-file corresponding to a second audio channel output (201); extracting from the first audio sub-file first audio data, and extracting from the second audio sub-file second audio data (202); acquiring a first audio energy corresponding to the first audio data, and acquiring a second audio energy corresponding to the second audio data (203); and determining, according to the first audio energy and the second audio energy, a characteristic of at least one of the first audio channel and the second audio channel (204).
(FR) La présente invention concerne un procédé et un dispositif de traitement d'informations audio. Le procédé de traitement d'informations audio comprend les étapes suivantes : décoder un fichier audio pour acquérir un premier sous-fichier audio correspondant à une première sortie de canal audio et un second sous-fichier audio correspondant à une seconde sortie de canal audio (201) ; extraire, à partir du premier sous-fichier audio, des premières données audio, et à partir du second sous-fichier audio (202), des secondes données audio ; acquérir une première énergie audio correspondant aux premières données audio, et une seconde énergie audio correspondant aux secondes données audio (203) ; et déterminer, en fonction de la première énergie audio et de la seconde énergie audio, une caractéristique du premier canal audio et/ou du second canal audio (204).
(ZH) 一种音频信息处理方法及装置,包括:对音频文件进行解码获得对应第一声道输出的第一音频子文件以及对应第二声道输出的第二音频子文件(201);从第一音频子文件中提取出第一音频数据,以及从第二音频子文件中提取出第二音频数据(202);获取第一音频数据的第一音频能量值,以及获取第二音频数据的第二音频能量值(203);基于第一音频能量值及第二音频能量值,确定第一声道和第二声道中至少一个的属性(204)。
