Digital audio aliasing is introduced when one attempts to record frequencies that exceed half the sampling rate.
在录音频率超过抽样频率的一半时，会造成数字音频混叠失真。

Contrarily,if the frequency bandwidth of signal is finite,the time length of signal will be infinite when sampling in frequency domain,the time folding phenomenon will certainly happen.
反之,若信号的频带宽度有限,当进行频域抽样时,时域必然发生混叠.

There is a penalty to be paid for the lower rate: a narrower band of frequencies will be recorded.
低取样率是有代价的：被记录的频率波段会很窄。

If the sampling frequency is less than this, we can expect a serious distortion of output frequency which is generally referred to as aliasing.
如果取样频率小于此数，那么输出频率就要产生严重畸变，通常假频指的就是这种情况。
