Description: ：针对MP3 编码方式和帧结构进行分析，利用帧中的比例因子提出了一种压缩域水印算法。算法通过引入帧变化分析步
骤，很好地实现了水印的自适应嵌入。对于不同的系统要求，还可以通过修改门限信噪比的值SNRlim按需进行水印嵌入，使算法
具有更大灵活性。同时在牺牲一定的嵌入空间前提下，实现了水印信息的自同步。实验表明，对于不同风格的音乐，该水印算法
具有很好的不可听性。-In this paper，the encoding method and the frame structure of MP3 are expounded in detail，a watermark algorithm
is proposed based on the scale factor in MP3 frame.By introducing the step of frame altering analysis，the algorithm
can realize that watermarks is embedded adaptively.By modifying threshold SNRlim（the ratio of signal to noise），the algorithm
can meet different requirements of some system，that is what enable the algorithm to have a bigger flexibility.Based on expense
of some embedding positions，the watermark can be embedded with self-synchronization.The experiment results show
this algorithm can get a good audio effect with various types of audio.

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.

Description: mp3播放源码，MP3功能的实现
7.1基本概念
PCM: 脉冲编码调制
声音是模拟量
计算机能处理的是数字量，涉及模拟量和数字量的相互转换
录音时是模拟量转数字量
播放时是数字量转模拟量
采样频率：
每秒钟抽取声波幅度样本的次数
当采样频率应该在40kHz左右，保证声音不失真
量化位数：
每次采样，模拟音频信号的振幅用多少个bit来表示
一般使用16bit
声道数：
有单声道和双声道之分，双声道又称为立体声
MP3：
音频数据的压缩算法
有损压缩（还原后是有失真的）
压缩比可以接近10:1-12:1
使压
缩后的文件在回放时能够达到比较接近原音源的声音效果(But for now, I only read simple English, I will not speak English.
I am Chinese, and I don't speak English. I really appreciate your help)
