说明：  编解码器（codec）指的是一个能够对一个信号或者一个数据流进行变换的设备或者程序。这里指的变换既包括将 信号或者数据流进行编码（通常是为了传输、存储或者加密）或者提取得到一个编码流的操作，也包括为了观察或者处理从这个编码流中恢复适合观察或操作的形式的操作。编解码器经常用在视频会议和流媒体等应用中(Codc refers to a device or program that can transform a signal or a data stream. The transformation referred to here includes not only the operation of encoding a signal or data stream (usually for transmission, storage or encryption) or extracting an encoding stream, but also the operation of restoring a suitable form of observation or operation from the encoding stream for observation or processing. Codec is often used in video conferencing and streaming media applications.)

改进后的SerialPort类文件，在编写串口程序时非常有用-improve the SerialPort types of documents, in the preparation of serial procedures will be very useful

说明：  语音增强或识别的语音源数据看IEEE_corpus(Speech Source Data for Speech Enhancement or Recognition,named IEEE_corpus)

无刷直流电动机需要多种电压电平来控制转速：0V 使电动机停转，5V 使电动机以最大转速运转，而在0V和5V之间的电压则使电动机以较低的转速运转-The needs of a wide range of brushless DC motor voltage level to control the rotational speed: 0V stop the motor switch, 5V maximum speed of the motor running, and in between 0V and 5V voltage while the motor running at low speed
