What’s The Difference Between DTS And Dolby Digital Sound?

In the world of audio technology, there are two big players: DTS and Dolby Digital. But what exactly sets them apart? Both DTS and Dolby Digital offer immersive and high-quality sound experiences, enhancing our movie-watching and music-listening escapades. However, there are subtle differences that distinguish these two sound formats. So, if you’ve ever found yourself wondering what sets DTS and Dolby Digital apart, fret not! This article will shed light on the distinctions between these two popular sound technologies, helping you make an informed decision when it comes to your audio preferences.


When it comes to sound quality, both DTS and Dolby Digital deliver exceptional audio experiences that enhance your entertainment. These two audio codecs are widely used in various devices and formats, ensuring you enjoy immersive sound whether you’re watching a movie, playing video games, or listening to music.

Sound Quality

Both DTS and Dolby Digital provide high-quality sound, but they utilize different compression methods to achieve this. DTS, short for Digital Theater Systems, uses less audio compression compared to Dolby Digital. This means that DTS can retain more detail and nuance in the audio, resulting in a more accurate representation of the original sound. On the other hand, Dolby Digital uses more audio compression, which can result in a slightly reduced audio quality, especially in complex and dynamic sound scenes.


Compression plays a crucial role in audio codecs, as it determines the file size and the amount of data transmitted. DTS uses a lower compression ratio, meaning it retains more of the original audio data. This can result in larger file sizes but offers the advantage of maintaining a higher level of sound quality. Dolby Digital, on the other hand, utilizes a higher compression ratio, balancing file size and sound quality effectively.


Bitrate refers to the amount of data transmitted per second in an audio file. In terms of bitrate, DTS usually has a higher bitrate compared to Dolby Digital. A higher bitrate allows for more data to be transmitted, resulting in more accurate sound quality with greater detail and depth. Dolby Digital, due to its higher compression, has a lower bitrate, which may lead to a slight compromise in audio fidelity, particularly in complex soundscapes.

Surround Sound Formats

Surround sound formats have revolutionized the way we experience audio, bringing depth and immersion to our entertainment.


DTS offers several surround sound formats, each designed to provide a unique audio experience. DTS-HD Master Audio is a lossless audio format that preserves all the original audio data, ensuring a faithful reproduction of the sound. DTS-HD High Resolution Audio offers a higher compression ratio with a minimal loss in audio quality, making it suitable for various applications. DTS:X is the latest addition to the DTS family and provides object-based audio, allowing sound to be positioned and moved around the listener for an even more immersive experience.

Dolby Digital

Dolby Digital, also known as AC-3, is a popular surround sound format used in a wide range of media. Dolby Digital delivers up to 5.1 channels of audio, including front, rear, and center speakers, along with a dedicated subwoofer for deep bass. This format offers a captivating audio experience, bringing movies and music to life. Dolby Digital also provides compatibility with older playback devices, ensuring widespread support for this audio format.

Dolby Digital Plus

Dolby Digital Plus builds upon the foundation of Dolby Digital, offering an enhanced audio experience. It provides greater audio fidelity, thanks to its enhanced bit rate and increased channel support. Dolby Digital Plus can deliver up to 7.1 channels of audio, creating a more immersive soundscape. This format is commonly found in streaming services and Blu-ray discs, providing high-quality audio for your home entertainment.

Dolby TrueHD

Dolby TrueHD is a lossless audio format that provides studio-quality sound reproduction, delivering audio with no loss in quality compared to the original recording. With its advanced coding algorithm, Dolby TrueHD can deliver up to 18 Mbps of data, resulting in an immersive audio experience. This format is often found in Blu-ray discs and high-end home theater systems, ensuring a truly exceptional audio performance.


When it comes to enjoying your favorite movies, TV shows, or music, compatibility is key. Let’s explore how DTS and Dolby Digital fare in terms of compatibility with different devices and formats.

Encoding Standards

To ensure seamless audio playback across different devices and platforms, encoding standards play a crucial role. Let’s dive into the encoding standards used by DTS and Dolby Digital.

Audio Encoding Formats

DTS and Dolby Digital utilize different audio encoding formats to compress and transmit audio data. DTS uses a pulse-code modulation (PCM) format, which preserves the original sound waveform in a digital representation. Dolby Digital, on the other hand, uses a perceptual audio coding format, which takes advantage of the human auditory system to reduce the amount of data required while maintaining audio quality.

DTS Encoding Standards

DTS offers various encoding standards to cater to different audio formats and delivery methods. DTS-HD Master Audio encoding is used for lossless audio delivery, preserving all the original audio data for maximum fidelity. DTS Express is a lower-bitrate encoding standard used for streaming and broadcast applications. DTS Neural:X is an object-based audio encoding technology that can upmix stereo or 5.1 content to deliver an immersive sound experience.

Dolby Digital Encoding Standards

Dolby Digital employs its own encoding standards to ensure consistent playback across different devices. Dolby Digital uses the Advanced Audio Coding (AAC) format for audio compression, allowing for efficient encoding and decoding of audio data. This format ensures compatibility with a wide range of devices and platforms, making Dolby Digital a versatile choice for audio delivery.

Channel Configuration

The channel configuration of a surround sound system determines the spatial placement of speakers, providing a three-dimensional audio experience. Let’s explore the popular channel configurations supported by DTS and Dolby Digital.

5.1 Surround Sound

The 5.1 channel configuration is one of the most widely used surround sound setups. It consists of five individual speakers: front left, front right, center, rear left, and rear right. These speakers work in conjunction with a subwoofer to deliver a captivating surround sound experience. Both DTS and Dolby Digital fully support the 5.1 channel configuration, ensuring an immersive audio experience for movies, music, and games.

7.1 Surround Sound

Building upon the 5.1 channel setup, the 7.1 surround sound configuration adds two additional speakers: rear center left and rear center right. This configuration provides enhanced spatial accuracy and immersion. Both DTS and Dolby Digital support the 7.1 channel setup, delivering a more expansive soundstage for a truly immersive audio experience.

11.1 Surround Sound

The 11.1 channel configuration takes surround sound to another level, offering a truly cinematic audio experience. This setup includes additional speakers placed high up in the room, typically above the main speakers. It provides a heightened sense of verticality and three-dimensionality, allowing sound to be positioned precisely. While both DTS and Dolby Digital support advanced multi-channel setups, it’s important to note that 11.1 configurations are less common and may require specialized equipment.

Broadband Bandwidth

As technology advances, so do the immersive audio formats. DTS X and Dolby Atmos are two such formats that have introduced new possibilities for audio reproduction.


DTS:X is an object-based audio technology that allows audio engineers to precisely position sound elements in a three-dimensional space.
