Although it has ended already, Universal is still thinking it is appropriate to do so in the taiwan disc, it is horrible.

For a CD with a sampling rate of 44.1 kHz, the theoretical maximum frequency that can be reproduced is half the sampling rate, or 22.05 kHz. Shouldn't there be a cutoff at around this frequency?
