The position of the subwoofer doesn’t need to be specific. In the case of the 5.1 setup, one speaker is placed in the center in front of the viewer, the other two speakers are placed at a 60-degree angle on both left and right sides, and the remaining two speakers are positioned at a 120-degree angle on left and right sides. The position of these speakers is critical in creating the surround sound effect. That said, both Dolby Digital and DTS support 7.1 speaker set ups and 6.1 speaker set up as well. On the other hand, DTS uses the Adaptive Differential Pulse-Code Modulation (ADPCM) algorithm to bring down the audio file size.īoth make use of the 5.1 surround sound setup, where five are speakers and one is a subwoofer.
Dolby Digital encodes audio in the AC-3 format and it uses Modified Discrete Cosine Transform (MDCT) algorithm to compress audio and reduce the audio footprint.
