opus

代码说明：

  在VS2010平台下用C语言开发的定点的opus编码和解码程序源码。程序经过了优化，在低码率下完胜HE AAC，中码率就已经可以媲敌码率高出30 左右的AAC格式，而高码率下更接近原始音频。(VS2010 platform in the C language development of fixed-point opus encoding and decoding program source code.The program is optimized in low bit rate HE win AAC rate can match the enemy rate is about 30 higher than the AAC format, and high bit rate closer to the original audio.)
