As home cinema has improved, new surround sound formats have sprung up – bringing more detail and realism to movie nights. But let’s go back to basics and look at the two most popular surround sound formats: DTS and Dolby Digital.
Both are audio compression technologies, allowing movie makers to record surround sound that can be reproduced in cinemas and at home. Both deliver multi-channel sound, so what’s the difference? And which is better?
The devil is in the detail. Or, more accurately, the way that the two techs encode audio.
DTS is encoded at a higher bit rate and therefore is considered by some experts to be better quality. Others argue that Dolby Digital’s technology is more advanced, and produces better sound quality at a lower bit rate.
