It is worth reminding that DTS is a format that is difficult to be compatible with devices such as LG and Samsung TV. So, Dolby Digital or DTS? This depends on your own different needs.
Usually, DTS encodes much more information on the surround channels than Dolby Digital.ĭTS Digital Surround – 5.1 maximum channel sound at 1.5 MbpsĭTS HD Master Audio – 7.1ch maximum sound at 24.5 Mbps (lossless quality)ĭTS HD High-resolution – 7.1ch maximum sound at 6 Mbpsĭolby Digital – 5.1ch maximum sound at 640 Kbps (common in DVDs)ĭolby Digital Plus – 7.1ch maximum sound at 1.7 Mbps (supported by streaming services like Netflix)ĭolby TrueHD – 7.1ch maximum sound at 18 Mbps (lossless quality available on Blu-Ray discs)Īs you can see, the DTS bit rate is generally higher than Dolby in the same channel, which results in a better DTS sound quality but a larger memory. While Dolby Digital rear channels are sometimes a tad too loud and must be attenuated on some discs. Surround Channels: DTS channel levels are usually very accurately transferred to disc. This is one of the reasons why music on a CD sounds better than Satellite Radio > Cassette > FM > AM. The higher the dynamic range, the better the difference between the loudest and softest sound reproduction. Clearly, DTS has a better dynamic range than Dolby Digital. DTS clearly appears to have better Dynamic Range overall than Dolby Digital. DTS and Dolby Digital are lossy, which means it has a degree of audio degradation from the original source, while others bypass the audio loss for lossless studio-level performance while still providing some compression to save space.ĭynamic Range: DTS has a way of knowing from the get audio source and created some super algorithm for their codec specifically so that this works effectively for their own. Since Dolby Digital made its debut in theaters in 1992, Dolby Digital 5.1 surround sound has become the standard for digital sound in both film distribution and cinema equipment.īoth DTS and Dolby Digital provide surround sound codecs for 5.1, 6.1 and 7.1 setups where the first number represents the number of small surround speakers, and the “1” is a separate channel for a subwoofer for its frequency range is only 1/10 of the standard channel.īoth formats use audio compression to save space.
DTS uses sound correlation to efficiently compress data so that the sampling rate reaches 192KHz at 24-bit. DTS stands for Digital Cinema System, a popular home theater audio format that was developed in 1993 as a competitor to Dolby Laboratories in the development of surround sound audio technology for film production.
