Was ist der Unterschied zwischen dts und Dolby Digital?

Klar dts hört sich einfach viel besser an, aber warum ist das so?
Antworten
In order to minimize the limited space allocated on a DVD for audio soundtracks, DD and DTS utilize lossy data reduction algorithms, which reduce the number of bits needed to encode an audio signal. DD compresses a 5.1 channel surround track to 384 kbps to 448 kbps (DVD Standard limited, DD has the potential of up to 640 kbps) while DTS uses much higher bit rates up to 1.4 Mbps for CD's / LD's and 1.5 Mbps for DVD. A higher bit rate must imply DTS will be superior sounding right? In theory, the less compression used in the encoding process, the more realistic the sound will be, as it will better represent the original source. DD tends to boast that its encoding method is more efficient than DTS and thus does not require the extra bit rates. However, even if DD is slightly more efficient, it is still not 1.5 / .448 = 3.35 times more efficient.. However, both DD & DTS will boast data rates, efficiency, etc, but what actually translates to better sound is a very ambiguous matter as there are more factors involved here that goes beyond the scope of this article.
