http://musicweb.ucsd.edu/~trsmyth/digitalAudio/Folding_Frequency.html Websampling frequency is too low. Frequencies "fold" around half the sampling frequency - which is why this frequency is often referred to as the folding frequency. Sometimes the highest frequency components of a signal are simply noise, or do not contain useful information.
