| aliasing |
a artifact of a discrete sampling process when the signal being sampled contains frequencies higher that half the sampling frequency. This can lead to misleading data.

If the sample rate of a function (fs) is less than two times the highest frequency value of the function, the frequency is ambiguously presented. The frequencies above (fs/2) will be folded back into the lower frequencies producing erroneous data.

In audio sampling, a distortion-producing reflection caused by the fact that all frequency components higher than half the sampling frequency are reflected in the lower range. Aliasing creates artifacts. It can be avoided by processing the waveform to be sampled with a low-pass filter at half the sample rate before digitizing.
