It’s the most common one and is found on CDs and DVDs (up to 778Kbps).ĭolby Digital Plus : Maximum bit-rate of 1.7Mbps in a 7.1 surround sound system.

One thing to note is that Netflix can move up to 768kbps with Dolby Atmos mix.ĭTS Digital Surround : Maximum bitrate of 1.5Mbps in a 5.1 surround sound system. The most common one is found on online streaming services like Netflix, Amazon Prime Video, and more. Here’s a look at the popular audio standards offered by both technologies:ĭolby Digital: Maximum bitrate of 640Kbps (Blu-ray Discs) and 448Kbps (DVD) in a 5.1 surround sound system. Compression level is another point that is considered. As a rule of thumb, if the audio has a higher bitrate, it will have a better sound quality and audio transparency. To put things into perspective, a high bitrate is one of the factors that is considered while determining the audio quality. The 6.1 setup involves the addition of only a single back speaker.īut some people regard DTS better than Dolby Atmos because it offers a higher bit-rate (640 kilobits as compared to 1.5 megabits in DTS).

As for the 7.1 speaker scenario, two more speakers are added to the back of the room. 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.

Dolby Digital vs DTS: What are the differences?īoth Dolby Digital and DTS use audio compressing tech to reduce unnecessary audio data while providing high-fidelity audio output.
