In an apparatus and method for reproducing digital audio data recorded onto a disc, the apparatus includes a first switching unit for outputting an audio signal of the AC-3 format to a first output port, for outputting an audio signal of the MPEG2 format to a second output port and for outputting a PCM audio signal to a third output port, an AC-3 decoding unit for extending input compressingly encoded 6-channel audio data of the AC-3 format and then restoring the same into 6-channel audio data, an MPEG2 decoding unit for extending input compressingly encoded audio data of the MPEG2 format and then restoring the same into 6-channel audio data, a PCM processing unit for audio-field processing input 2-channel linear PCM audio data and then converting the same into 6-channel audio data, a second switching unit for selectively outputting audio signals of the first through third input ports to an output port, a unit for converting and outputting input audio data into analog audio signal, and a unit having six speakers for reproducing the 6-channel analog signal. |
