| Okay, then here's the technical reason: CDs are sampled at an
| insufficient rate to ensure proper reproduction. CDs are sampled at
| 44.1kHz, which gives a maximum frequency of 20kHz.
22.05, actually, due to the phenomenon known as "aliasing".
[...]
| This is one of the motivations behind SACD and DVD-Audio, which sample at
| 96kHz, if my memory is correct.
DVD-Video's audio formats, dts and Dolby Digital (AC-3) have the capability
to handle sampling rates up to 96KHz, providing a frequency response of up
to 43KHz. That does not mean all DVD-Video discs will have dts (many do
not), Dolby Digital (some do not), or sampling rates nearly that high (very
few do).
| Of course, those formats also do 5.1, which I find ridiculous, but that's
| my personal opinion.
I think that if you had five surround speakers plus a super subwoofer, you
would think differently.
