The Griffin iMic is our audio input device of choice .

GriffiniMic是我们选择的音频输入设备。

However , in line with the modest capabilities of the iMic , our target for this series is to work with two parallel ( stereo ) 44.1kHz16-bit data streams , implying an audio bandwidth of22.05kHz .

然而，为了让iMic具有适度的性能，我们在本系列文章中的目标是处理两个并行的（立体声）44.1kHz的16位数据流，这就意味着要实现22.05kHz的音频带宽。

I am using a standard NTSC television set as my output device and I also added a vanilla USB keyboard and mouse and a Griffin iMic to the system ( more on that peripheral later ) .

我使用了一个标准的NTSC电视机作为输出设备，还向系统中增加了一个vanillaUSB键盘和鼠标以及一个GriffiniMic（稍后将对这些外围设备作更详细的介绍）。

In the next article , I 'll describe how to use the iMic to gather an analog data stream , and I 'll show you how to use one of the SPEs to turn the system into a useful spectrum analyzer .

在下一篇文章中，我们将介绍如何使用iMic来搜集模拟数据流，并展示如何使用一个SPE将系统转换成一个有用的音频分析器。
