The paper describes a low-cost MPEG-2 audio decoder with a modified fast algorithm for decoding. In the modified decoding scheme, the computation amount of the bottleneck module can be reduced into one-forths of the original one. Also, the major memory storage only requires half size of the standard synthesis subband filterbank. The decoder is developed for the approaches of simplicity and low-cost architecture design, with the techniques of intelligent data arrangement and memory configuration
