The present invention relates to a method of calculating temporal information of frame-based audio stream data, and more particularly, to a method of calculating temporal information of frame-based audio stream data, in which it can calculate time related information depending on the playback of stream data even when bitrate or timetable information is not included in header information when audio or voice stream data consisting of a frame format are played back. Audio and voice stream data applied at this time includes stream data of a type in which several frames form one bit stream block as well as stream data constructed on a frame basis.

Method of calculating temporal information of frame-based audio stream data

An apparatus for decoding audio data that is capable of reducing the amount of calculations that are performed during the arithmetic decoding of an audio signal coded by bit sliced arithmetic coding (BSAC) to improve the performance of a decoder and a method thereof are provided. According to the embodiments of the present invention, it is possible to reduce the amount of calculations that are performed during the arithmetic decoding of an audio signal in the BSAC to 1/16 of the amount of calculations of the conventional full search method
