This solution would call for multiple sound output devices (on many systems, programs such as Festival and MPlayer can direct the output to a specific device) or coordinated input to one device.

这种解决方案需要调用多个输出设备(在许多系统中，Festival和MPlayer等程序可以将输出发送到特定的设备)或者在一个设备上协调输入。

You'll get 20 to 30 lines of output, one line per "device".one of the interesting lines on my computer says.

你会得到20到30行输出信息，每一行表示一个“设备(device)”。

One example of a multiple closure would be to route a single device output to two instruments, such as a voltmeter and a frequency counter.

复用开关的一个简单例子就是将单台设备的输出连接到2台仪器，例如一台伏特表和一台频率计数器。
