本人嵌入系统中的源代码，经过实际测试，绝对正确；它实现从文件中读取音频数据并播放的功能！-I have the source code for embedded systems, through the actual testing, is absolutely right it implements the audio data read from the file and play features!

可以调节当前系统声音大小的一个例子。xp系统测试过。其他系统没测试过-You can adjust the size of the current system an example of the sound. xp system tested. Other systems not tested

音频系统，coding, modulation, AWGN, 通过最小距离探测码元，解码，播放。根据不同的SNR，测试在多小的SNR情况下，人耳能识别音频。-Audio systems, coding, modulation, AWGN, by minimizing the distance detection symbol, decoding, playing. Depending on the SNR, the test in the case of multiple small SNR,

能够自动找到所有可用的录音设备和播放设备, 实现边放边录. 主要用来测试音频系统和音频算法(Can automatically find all available recording equipment and playback equipment, play while record to test an audio system or algorithm)
