Title (EN) APPARATUS AND METHOD OF PROCESSING AN AUDIO SIGNAL
(FR) APPAREIL ET PROCEDE POUR TRAITEMENT DU SIGNAL AUDIO
Abstract:
(EN) In one embodiment, sample information and frame length information are obtained from the audio signal. The sample information indicates a total number of audio data samples for each channel in the audio signal, and the frame length information indicates a number of samples in a frame of each channel. It is determined if a remainder exists if the sample information is divided by the frame length information, and if a remainder exists, the number of frames in the audio signal is determined as an integer value of the sample information divided by the frame information plus one. Also, a length of a last frame may be set based on the remainder if the determining step determines that a remainder exists. The data samples are decoded based on the determined number of frames.
(FR) Dans un mode de réalisation on déduit du signal audio une information d'échantillon et une information de longueur de trame. L'information d'échantillon porte sur le total d'échantillons de données audio pour chaque canal du signal, l'information de longueur de trame correspondant au nombre d'échantillons dans une trame de chaque canal. On considère qu'il y a un reste si l'information d'échantillon est divisée par l'information de longueur de trame, et s'il y a un reste, on calcul le nombre de trame du signal audio comme un entier de l'information d'échantillon divisé par l'information de trame plus un. Ainsi, la longueur de la dernière trame peut se définir sur la base d'un reste si le calcul fait apparaître un reste. Pour décoder les échantillons de données, on se base sur le nombre de trames calculé.
