Abstract:
1. An audio data processing apparatus, comprising: a dividing device that partitions PCM audio data into a plurality of frames, divides the PCM audio data into a plurality of divided data and structures each of the divided data to have main data sections for the plurality of frames and overlapping sections overlapping with the plurality of frames in a previous divided data and a following divided data; an encoder that encodes each of the divided data one by one at a variable bit rate and writes the encoded audio data continuously without a space between the frames; an analyzer that searches frames in the overlapping sections of a present divided data and the following divided data encoded by the encoder, in which a beginning point of the encoded audio data written into the frame in the present divided data and a beginning point of the same encoded audio data written into the frame in the following divided data are closest in positions but not overlapped; and a combining device that combines the divided data at the searched frames.
