You are mixing up amplitude (loudness) with frequency. The Nyquist theory is all about the highest frequency that can be reconstructed from a given sampling rate (i.e. half the sampling frequency). If you try and record frequencies at more than the Nyquist limit, what happens is that they are 'folded down' into the allowed frequency giving rise to distortion, known as aliasing. Aggressive filtering is used to stop freqencies above 22.05 Khz being allowed into the ADC.
Clipping occurs when the amplitude of the input signal is allowed to exceed 0db. This can happen whatever the frequency, and is caused by engineers pushing up the average level of a track so that the peaks exceed 0db. -- bigfool1956 David Ayers Music is what counts, hifi just helps us enjoy it more ------------------------------------------------------------------------ bigfool1956's Profile: http://forums.slimdevices.com/member.php?userid=13782 View this thread: http://forums.slimdevices.com/showthread.php?t=45107 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
