Simulation Study on MPEG64kb/s Hi-Fi Audio Compression Algorithm

Yu Yuan et al.  
 MPEG/Audio layer Ⅲ,a powerful digital audio compression scheme,provides high sound quality being close to that of CD even at very low bit rate.A study on algorithm simulation of MPEG/Audio layer Ⅲ is described in this paper.The main points in the implementation of this algorithm are put forward.For something being not proper in coding example in the standard,an improved scheme is proposed. Compression coding at 64kb/s per channel of HiFi signal is implemented by C language.After coding/ decoding,the recovered sound signal is heard without quality impairment.Finally,the requirements of operational quantity and storage capacity of real time implementation for this algorithm are estimated by DSP.
