Ever since the invention of these two technologies, there has been an ongoing debate about their superiority. Some claim that Dolby is the best technology. Some others argue that it is DTS who has the upper hand. This article will discuss Dolby and DTS and their features. At the end of the day, we will try to determine which of these devices has the edge over another.

Bitstream Dolby VS DTS

What is Dolby?

What is Dolby

Dolby or Bitstream Dolby or Dolby Digital is a next-generation audio codec. It offers realistic surround sound quality. This audio system is developed by Dolby Labs. They are the inaugurator of this incredible tech. This thing is an audio compression technology. It is also known as surround sound audio tech. This tech is mostly used by movie productions all across the globe. To work this system, firstly, a user must have to record the sounds using this technology.

Then the sounds become real surround sound as if it is coming from the direction of the real sources. And the sound is surrounding you from every direction. To put it more simply, we can elaborate on this. Imagine you are watching a movie. In the movie, a car is approaching from the left side of the screen. Now if you have Dolby Digital speakers or headphones installed, you would hear the car’s sound approaching from your left-hand side. This is the digital sound tech of Dolby Digital.

This very thing gives a realistic touch to the sound quality. It seems that you are standing right beside the sound sources. The first film that introduced us to this tech was Batman Returns. It was published in 1992. Now take a quick look at the sound compression and bit rates, and some other features of Dolby Digital audio tech.

Dolby Digital is the very first tech of its kind. They introduced us to the next-generation audio systems. We are blessed by the surround sounds of Dolby Digital. Let’s scroll down to learn some features of this incredible tech.

  • Compression and Bit Rate: The sound which is encoded to a higher bit rate the better sound quality it produces. It can compress 5.1ch data of digital audio to 640 kilobits per second. It is only supported for Blu-Ray discs.  For other DVDs, this tech compresses to 448 kilobits per second.
  • Bit Rate of other Dolby Versions: Dolby Digital Plus compresses 7.1ch data of the digital audio to a bit rate of 1.7 megabits per second. It is supported by various stream services like Amazon Prime Video, Netflix, and Disney+, etc. The Dolby TrueHD version encodes even at a larger bit rate. It compresses 7.1ch digital audio to the bit rate of 18 megabits per second. It is available on Blu-ray discs. It is a lossless quality audio system.
  • Advanced Codecs: The codec quality of Dolby is very advanced. That is why it can produce a good signal-to-noise ratio sound.
  • Multi-Channel: Dolby supports multi-channel speakers. Dolby Digital 5.1ch supports 5 speakers and 1 subwoofer. The upgraded versions such as Dolby Digital Plus and Dolby Atmos support 7.1 channels. That means HD surround sound with an overhead speaker.
  • Incredible Listening: The quality of Dolby is beyond ordinary listening. This tech puts you inside the sound. It also produces wonderful clarity of sounds.
  • Good For Creators: Dolby Digital helps the creators to produce good quality sound. It produces exactly what the audience wants to hear.
  • Dolby for Cars: You can set up Dolby sound systems in your car. The sound surrounds you so well that it moves all around you.
  • Your best Audio Experience: Dolby offers you realistic surround sounds in every sector of entertainment. You can enjoy it in-home theatre, watching movies, playing games, and listening to music, and any other videos.
  • Formats: It supports Blu-ray discs, games consoles. It also supports home theatres, computers, and set-top boxes. But the most incredible thing is that it supports smartphones.

What is DTS?

What is DTS

In this section, we will take a quick note about what DTS is. Then, we will try to figure out which one is the best.  DTS stands for Digital Theatre Systems. It is also a multi-channel, and the digital audio surrounding system. It provides realistic and cinematic surround sound just like Dolby.

It was coined back in 1993 as a competitor of Dolby. They amazed us with their high bit rate audio encoding ability. DTS can encode digital audio at a higher bit rate with a lower compression than Dolby. DTS is developed by Multichannel Audio Technologies Company, Calabasas, California. DTS was first used in the film named Jurassic Park back in 1995. Now, let’s take a quick look at the DTS versions, compression, and bit rate along with features.

Digital Theatre Systems or DTS is amazing as they are competing with Dolby tech with equal strength. Many believe that DTS has a slight upper hand. Let’s check out its features.

  • Compression and Bit Rate: DTS compresses less with a higher bit rate. It can encode sounds with compression of 5.1ch digital audio data to a bit rate of 1.5 megabits per second.
  • Bit Rate of other DTS versions: The higher versions encode with even a higher bit rate. The DTS-HD High-Resolution 7.1ch encodes with a bit rate of 6 megabits per second. DTS also has a lossless version like Dolby TrueHD. The name of it is DTS-HD Master Audio.
  • Multi-Channel: DTS supports multi-channel speakers. DTS 5.1 multi-channel is an example. 7.1 multi-channel is available in DTS:X, DTS-HD Master Audio, and DTS-HD High-Resolution.
  • Formats: DTS is available in Blu-ray and DVD formats. Games consoles, musical apps, streaming services are also including DTS. Almost 90 percent of the cinematic sound’s equipment supports DTS.

The Difference – Dolby vs DTS

In this section, we will try to figure out which of the surrounding sound technologies is better. You may know that it is a very hot debating topic. Some people believe that DTS tech produces more realistic sound. Others argue that Dolby tech has the most advanced codecs. It helps Dolby to produce a more clear and realistic sound. This debate is ever ongoing. Here we will bring some facts about their encoding systems to determine which one is best.

Encoding Sounds- Compression and Bit Rate

Encoding Sounds- Compression and Bit Rate

In theory, the less compression and more bit rates during encoding the more realistic the sound gets. Encoding in higher bit rates produces more realistic sounds. DTS tech has an upper hand in this regard. It encodes sound at a bit rate of 1.5 megabits per second.

It is only 640 kilobits per second for the Dolby tech. So, in theory, DTS produces more cinematic and realistic sounds. But good sound quality does not depend merely on bit rates. Many argue in defense that Dolby Digital tech has more advanced codes.

They argue that Dolby produces more realistic and clear sounds in real life. But we can tell you that you don’t have to choose between DTS and Dolby. You can pick anyone as both of them are exceptionally incredible in cinematic surround sound systems.

Versions and Multichannel

Versions and Multichannel

Both DTS and Dolby have produced some exciting upgrade versions over the years. Dolby has Dolby Digital Plus, Dolby TrueHD, and Dolby Atmos. On the other hand, DTS has DTS-HD High-Resolution, DTS-HD Master Audio, and DTS:X in their possession. Both of the systems have 5.1ch and 7.1ch systems.

Streaming Services

Streaming Services

Nowadays, streaming services are one of the most popular sources of entertainment. We want to mention here that Netflix, Amazon Prime Video, and Disney+ currently use Dolby Atmos. DTS is yet not available here.



Dolby Atmos requires an overhead speaker to give you the ultimate surrounding cinematic sounds. Many people may not feel comfortable putting a speaker overhead. Dolby Atoms has other solutions too. The Dolby Atmos soundbars fire the sound upward and give you the same sensation or even better.

DTS:X is far simpler. And maybe more efficient. You don’t need to install an overhead speaker. DTS:X allows you to manually upper or lower the soundtracks and voices. DTS:X gives you the same sensation of cinematic surround sounds.

The Bottom Lines

Both DTS and Dolby are incredible next-generation audio systems. They help us to get more involved with the movies. As if they send us into virtual reality with the realistic surrounding sounds. As we mentioned earlier, they are so good that you don’t have to choose between them. Both are better. But one thing is certain that Dolby is more common. It is available for Netflix and Amazon Prime Videos, but DTS is not at the moment. I hope now you know about Bitstream Dolby VS DTS.
