The main difference between DTS and Dolby Digital is seen in the bit rates and compression levels. Differences Between DTS and Dolby Digital DTS also has a lossless version, DTS-HD Master Audio, that supports 7.1 channels speaker setup. The lossy version takes up very little space on Blu-Ray discs. Dolby, for example, has a lossless version, Dolby TrueHD, and a lossy version, Dolby Digital Plus. Some versions of Dolby Digital and DTS are “lossy” which means they have a degree of audio degradation from the original source while others are lossless. For instance, DTS and Dolby Digital use compression to save space either on the disc, as is the case with Blu-Ray and DVDs or on streaming bandwidth for services like Netflix. ![]() Both DTS and Dolby Digital provide surround sound codecs for 5.1, 6.1 (rare) 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.īoth formats utilize “perceptual” data reduction techniques to remove useless data in PCM signal output, thereby preserving high fidelity sound. In addition to the 5.1 to 7.1 speaker playback, different formats offer cutting edge audio technology geared toward enhancing the sound quality. DTS stands for Digital Theater Systems, a popular home theater audio format that was developed in 1993 as a competitor to Dolby Labs in the development of surround sound audio technology for movie production. Dolby Digital is the name for audio compression technology developed by the Dolby Labs. ![]()
