    摘要: Provided are a lossless audio coding/decoding apparatus and method. The lossless audio coding apparatus includes a first coder to directly code first symbols; a second coder module comprising a plurality of second coders to convert the first symbols into second symbols and to code the second symbols; a first selector to compare the performance of the first coder to the performance of the second coders and to output a coding mode in accordance with a comparison result; and a second selector to output a final bitstream by coding the first symbols in correspondence with the coding mode. According to the present invention, the performance of audio coding may be improved.
