The experimental results show that the algorithm is very robust to re-sampling, re-quantization, lowfilter, amplitude attack, etc.
实验结果表明，算法对于重采样、重量化、低通滤波和幅度攻击等都有很好的鲁棒性。

The joint interface is like a lowfilter, the higher frequency will be easily reflected, and the lower frequency will be easily transmitted.
节理面呈现出低通滤波器功能，频率越高越容易被反射，越低则越容易透射；

The Affective filter Hypothesis implies that our pedagogical goals should not only include supplying comprehensible input, but also creating a situation that encourages a lowfilter.
