MP3, Decoder, VHDL


MP3 has become one of the most popular standards for digital audio and video broadcasting. High compression ratios offered by MP3 codecs in various standalone players and hand held devices over the last few years has increased its popularity immensely. Internet users, music lovers who would like to download highly compressed digital audio files at near CD quality are the most benefited. Psychoacoustic model, Modified Discrete Cosine Transform (MDCT) and Huffman coding play a vital role in achieving such magnificent compression ratios. In this work, the performance and result of each different block of Mp3 decoder is shown in VHDL using Modalism as the simulation tool. Testing and simulation were made to ensure full functionality of the design. An MP3 song of 128bitrate, 44 KHz and single channel is selected for the simulation. The simulation results show the effectiveness to implementation of Mp3 decoder in VHDL.
