This is not true. Alot of people tend to beleive it is true, and so did I not too long ago.

However, it's not at all trivial to understand why this isn't true.

The CD-format, if implemented correctly, can reproduce all waveforms < 22.05kHz perfect. The mathematics behind this is called the Sinc-function: http://en.wikipedia.org/wiki/Sinc_function

I understand this enougth to understand that it's true, but I do not understand it well enougth to explain it, so please don't ask questions.
