Mp3解码过程,总体上可分为9个过程：比特流分解，霍夫曼解码，逆量化处理，立体声处理，频谱重排列，抗锯齿处理，IMDCT变换，子带合成，pcm输出。 -Mp3 decoding process, on the whole can be divided into nine process: bit-stream decomposition, Huffman decoding, inverse quantization processing, sound processing, spectrum

实现PCM编码和解码，这是完成数据填充到WAV文件中的重要的一步-PCM encoding and decoding to achieve, which is the completion of data into WAV file, an important step

音频编码解码器库,采用C++语言实现，库集成了所有支持格式（mp3, mp2, mp1, ogg, flac, ac3, aac, oga, wav and pcm ）的编码解码器-libZPlay is about decoding audio by c++
