手把手教你远程控制树莓派的GPIO！！！！（中级教程之五）

非常不错，不过看了下官方有这么个说法

Note that this module is unsuitable for real-time or timing critical applications. This is because you can not predict when Python will be busy garbage collecting. It also runs under the Linux kernel which is not suitable for real time applications - it is multitasking O/S and another process may be given priority over the CPU, causing jitter in your program. If you are after true real-time performance and predictability, buy yourself an Arduino http://www.arduino.cc !

太专业了。。。不知道解压1bit音频算不算realtime application 呢？我的i5 CPU 占用率达到45%，是不是意味着RPI一定不能够完成了？
