What is DTS?
DTS stands for Digital theatre system is a company that makes multichannel audio technologies for films and videos, by enhancing the sound quality of it.this company specializes in digital surround sound system.
DTS company is based in Calabasas, California and was introduced in 1993 as a higher quality competitor to Dolby Laboratories and undoubtedly accomplished the goal of being better in the market.
DTS is also known as their technology. It is the technology which makes audios more loud and clear, making films appropriate for the theatre audience for the people who have home theatre.

And different versions are used for different purposes. For example for the real theatre there is a different version that will be used and for home purposes a different version is used.
DTS has a working system in which six different audio channels are encoded on to one or two CDs. in theatres there are many decoders and CD players which enable to separate the sound onto different speakers as per the need.
DTS uses higher bits which makes the sound quality more appreciable, for the home theatre version the most appropriate version is 5.1- channel audio , which gives the exact cinematic feel to the audience with speakers and subwoofers. And the most u[graded version is 7.1- channel audio.
DTS offers the most advanced surround sound formats including DTS-HD which supports the 7.1 speakers channels. There are other versions as well like DTS-HD Master audio and DTS:X (this version competes with dolby atmos).
DTS is less compressed and supports a high bit rate of up to 1.5mb/s and for DVDs it supports 768 kbits/s. Less compression during encoding enables more detailed audio which makes it fit for the audience.
What is AC3?
AC3 is the audio compression technology introduced by dolby digital which is also known as Dolby AC3. This technology is developed under Dolby laboratories. AC3 is basically the term which is being used in place of dolby digital.
