The corrupted parts of the bit-streams may not only affect the reconstruction effect of the current frames, but also cause the error propagation problems both spatially and temporally.
由于目前常用的编码器普遍采用“预测-残差”方式进行编码，因此一旦传输发生错误，不仅会影响当前帧的重建，更会造成空间及时间上的误差蔓延。
As a bit of helpful trivia, each application is initially opened with three file descriptors, 0 through 2, for the standard input, output, and error streams, respectively.
有一点不是很重要但却很有帮助，初始打开每个应用程序时，都具有三个文件描述符，从0到2，分别表示标准输入、输出和错误流。
However, in line with the modest capabilities of the iMic, our target for this series is to work with two parallel (stereo) 44.1khz 16-bit data streams, implying an audio bandwidth of 22.05khz.
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)44.1 kHz的16位数据流，这就意味着要实现22.05 kHz的音频带宽。
