MPEG 1 – Layer III Audio Codec Brad Erwin Mary Lou Kesse Date: 03/25/99 2 1 Project Summary For our senior project, we propose to develop an MPEG-1 Layer III (MP3) audio decoder with a Texas Instruments TMS320C6x digital signal processor (DSP). Achieving this goal requires a thorough investigation of the MPEG coding algorithm, the
Real Time MPEG1 Audio Encoder and Decoder

A block diagram of the MPEG1 audio system is shown in Fig. 3. Since SSP1605 is a general purpose DSP, several interface units are required to implement specific DSP application such as MPEG1 audio. Required interface units, which are designed in a FPGA of 2K gate, are MIU (Memory Interface Unit), CIU (Codec Inter-face Unit) and HIU (Host Interface Unit).

in the file is an encoded chunk of 1152 time domain audio samples. These samples are then divided into two granules each, resulting in 576 samples. Every frame consists of a header, side info, audio data, and ancillary data. The header frame is 32 bits long. For an MPEG-1 mono audio file, the side frame is 17 bytes long.

The Graphic Equalizer in the DSP component provides 20 bands of equalization which is applied to mpeg wave file (mpg, mp1, mp2, mp3) playback. JetAudio provides 6 pre-defined equalizer sets such as POP, ROCK, JAZZ, CLASSIC, VOCAL and FLAT. If you want to configure the equalizer by yourself, select [User] Mode and then set it as you want just like drawing with a mouse.
