Abstract:
1. A digital data reproduction apparatus, comprising: a memory for temporarily storing audio data within digital data recorded on a recording medium; a digital/analog converter connected to the memory and also connected to a sound output device; and a data processor causing the memory to store the audio data recorded on the recording medium, wherein the data processor performs special processing on the audio data stored in the memory such that processed audio data is output through an intended channel of the sound output device, the data processor sends the processed audio data to the digital/analog converter, the memory includes a first area for storing first channel digital data and a second area for storing second channel digital data, the special processing is processing that stores a portion of the processed audio data to be output through a first channel of the sound output device as first channel digital data in the first area, and stores a portion of the processed audio data to be output through a second channel of the sound output device as second channel digital data in the second area, the digital/analog converter converts the first channel digital data stored in the first area into first channel analog data and sends the first channel analog data to the sound output device to be output through the first channel, and converts the second channel digital data stored in the second area into second channel analog data and sends the second channel analog data to the sound output device to be output through the second channel, the first channel digital data stored in the first area is copied and stored in the second area when the first channel digital data is to be output through the second channel, and the second channel digital data stored in the second area is copied and stored in the first area when the second channel digital data is to be output through the first channel.
