MPEG Layer 3 (and 2 and 1, and MPEG 2) decoder for Cool Edit
------------------------------------------------------------------------
Based on the code from \"maplay\" version 1.2. See mp3.c for more details.
If you used our other MPEG filters (MPE.FLT and MPG.FLT) you should
remove MPG.FLT and use this decoder (MP3.FLT) instead.

Description: Realizing an MP3 player with the LPC2148, using libmad and
EFSL This Application Note describes how to integrate the libmad MPEG 1/2 layer 3 library and
the Embedded File System Library EFSL in a LPC2148 device to realize MP3 player.
The Keil MCB2140 board is used to test the application and the Rowley CrossStudio for
ARM has been chosen as a reference tool-chain. -Realizing an MP3 player with the LPC2148, using libmad and EFSL This Application Note describes how to integrate the libmad MPEG 1/2 layer 3 library and the Embedded File System Library EFSL in a LPC2148 device to realize MP3 player.

Description: MONOGRAM MPEG Audio Encoder 0.9-after a while there’s yet another new encoder available :). I have created an MPEG Layer 2 encoder based on the libavcodec (ffmpeg) source code. Unluckily the libavcodec encoder lacks a nice psychoacoustic model so I’m considering taking a look at the TwoLame library. Until then please do some testing and if you find any problem with the filter please do report it. This filter is released under the GNU LGPL license.

Description: 首先介绍了MPEG－2音频layer Ⅲ（MP3）的解码算法，详细地叙述进行定点C语言仿真的技巧。基于TI公司的’C549 DSP芯片进行汇编工作，在TMS320C549 EVM板上实现了网上MP3文件的连续播放，效果满意。经过对算法和程序的优化使所需的运算量和存储空间都很低，使能在TI公司的低价型’C5402 DSP上实现。-First introduced the MPEG-2 audio layer Ⅲ (MP3) decoding algorithm, a detailed account of the fixed-point C-simulation techniques. Based on TI' s' C549 DSP chip assembly work in TMS320C549 EVM board to achieve an online MP3 file of continuous playback, the effect is satisfactory. After the optimization of algorithms and procedures to make the necessary computation and storage space are very low, so low in TI' s type ' C5402 DSP to achieve.
