    • There is provided with an encoded digital audio reproducing apparatus including: a reading control portion which reads an encoded audio file having a data part including audio data as a sequence of frames and a size part including size information on each of the frames; a table generating portion which generates a table holding positional information on frames at intervals of a predetermined number of frames in the sequence of frames; a decoding portion which sequentially decodes the audio data from a leading frame to output the decoded audio data; a reproducing portion which reproduces the decoded audio data; and a reproduction start position calculating portion which, in the case where a reproduction request from an arbitrary frame in the audio data is inputted, decides from the table a frame satisfying a positional reference for the arbitrary frame as a reproduction start frame.
    • 提供了一种编码数字音频再现装置,包括:读取控制部分,其读取具有包括作为帧序列的音频数据的数据部分的编码音频文件和包括每个帧的尺寸信息的大小部分; 表格生成部,其生成以帧序列的预定帧数的间隔保持关于帧的位置信息的表; 解码部分,其从前导帧顺序地解码音频数据,以输出解码的音频数据; 再现部分,其再现解码的音频数据; 以及再现开始位置计算部分,其在输入来自音频数据中的任意帧的再现请求的情况下,从表中确定满足任意帧的位置参考的帧作为再现开始帧。
