Multimedia Audio Digital Signal Processing And Realization

This paper fOcus on t11e issues of tIle real-time realizatio11 of tl1e MP3encode an decoder.In order to unfold the whole essay, a general description of the preselltresearch condition in the field of digital audio signal processing especially inthe field of digital audiO signal compression is presented. Then, we give tIleintroduCtion of the theory of digital audio signal compression, the algorithmand somp accelerate algorithm for the MP3 encode and decode. ln the end, wepropose a parallel processing system with two DSP to be a real-time MP3encoder and decoder.Still, we generalize our work and give a preview of the prospect in thedigital audio signal compression field.
