What is DTS Virtual:X? The Magic Behind This Surround Sound Format

DTS Virtual:X is an audio technology that makes you feel like sound is coming from everywhere around you (above, beside, and behind) without needing a bunch of speakers all over your room.

Instead of having to use multiple speakers in a full surround system, DTS Virtual:X uses advanced sound processing to create a theater-like, virtual 3D audio experience through the speakers already built into compatible devices, like TVs, soundbars, and AV receivers.

For some, this technology might be integrated into devices you already own. If not, you’ll need to purchase a compatible device to take advantage of DTS Virtual:X.

It’s an easy and cost effective way to enjoy immersive sound without the need to install any additional equipment or speaker wires.

This article will answer your questions about DTS Virtual:X, explain how it works, and help you decide if it’s the right choice for upgrading your sound system.

What is DTS Virtual:X and How Does it Work?

DTS Virtual:X tricks your ears into believing sound is coming from places where no speakers exist. This is done by creating depth and dimension to the audio, simulating surround sound and height effects for a layered and spatial audio experience.

The technology analyzes audio signals intended to come from specific directions—like overhead or behind—and adjusts their frequency, timing, and volume to position them as though they’re coming from those areas.

For example, rain sounds like it’s falling from above, and footsteps approach from behind, even though, in reality, all the sound is coming from speakers in front of you.

Key techniques used behind the scenes:

Psychoacoustics
Surround and Height Effects
Low-Frequency Boost

Here’s how each one works:

Psychoacoustics: How Your Brain Interprets Sound

DTS Virtual:X relies on psychoacoustic principles, which is how your brain processes sound cues like timing, frequency, and volume. These cues are manipulated to create a 3D sound effect, even with front-facing speakers.

Time Delays: Slight timing delays mimic the natural lag of sound waves traveling to each ear, making audio appear to come from specific directions.
Frequency Adjustments: Replicates how higher frequencies fade quicker than lower ones, tricking us into perceiving distance or elevation so sounds seem closer, farther away, or above you.
Amplitude Variations: Small changes in volume dynamically adjust the loudness of sound, creating the illusion of movement. This is what makes it feel like the sound is shifting positions and moving around you.

Your ears are convinced that sound is happening all around you, even if the speakers are in front.

Virtual Height Channels

DTS Virtual:X simulates vertical sound—something that used to only be possible with ceiling speakers or upward-firing drivers.

It identifies sounds that naturally occur above, like birds chirping in trees or a plane flying overhead, and processes them to seem like they’re coming from that direction.

These sounds are played through front or side speakers using height virtualization algorithms, creating a convincing sense of vertical audio.

Sound That Surrounds

DTS Virtual:X also improves the horizontal audio plane, simulating rear and side channels.

Here’s how:

Phase Shifting: Slightly shifts the phase (timing) of certain audio signals, which helps create the perception that sounds are originating from behind or to the sides.
Channel Steering: The system dynamically adjusts where sounds “appear” in space, even if the soundbar or TV only has two or three physical channels.
Reflection Mimicking: By emulating how sound waves bounce off walls in a room, DTS Virtual:X makes it feel as though audio is reflecting from specific directions, creating an enveloping surround sound effect.

These techniques work together to expand the soundstage, giving you the sense that audio is not just in front of you but filling the entire room.

Low-Frequency Enhancement (Bass Boost)

On top of handling directional sounds, DTS Virtual:X also strengthens bass for a more impactful sound.

The technology identifies low-frequency signals (like explosions, rumbles, or bass lines) and amplifies them.
Even with smaller speakers, you still get a full, powerful sound experience.

This bass enhancement adds weight to the overall audio, making effects like explosions and storms feel more real.

What Equipment Do You Need for DTS Virtual:X?

One of the most appealing things about DTS Virtual:X is the fact that you don’t need an expensive multi-channel surround sound system to experience it.

Since its introduction in 2017, brands have been integrating it into their devices for users who are looking to upgrade their home theater setup, want more realistic gaming experiences, or just want better sound quality but are on a budget.

Compatible Devices

DTS Virtual:X is built into many modern soundbars, TVs, and AV receivers from partnering manufacturers like Yamaha, LG, Sony, Samsung, Denon, and Onkyo.

The technology requires devices with the Virtual:X engine built-in and proper licensing.

Minimum Requirements

DTS Virtual:X isn’t limited to high-end audio setups. It adapts to different hardware and works within its constraints, making it accessible with compact or budget-friendly devices too.

The algorithms are optimized to take advantage of the number of speakers available in any given device, whether you have a basic two-speaker setup or a more advanced multi-channel system.

For Smaller Systems: With just two speakers in a soundbar or TV, DTS Virtual:X can create impressive surround and height effects, delivering a multidimensional sound experience without adding extra hardware.
For Multi-Channel Systems: In 3.1, 5.1, or 7.2 surround sound setups, DTS Virtual:X adds the vertical dimension that’s missing from these configurations. Instead of requiring ceiling or upward-firing speakers, it uses virtual height effects to deliver an even richer audio experience.

Limitations

While DTS Virtual:X offers impressive sound enhancements, there are a few things to keep in mind:

Hardware Limitations

The quality of your experience depends on the speakers in your device. Entry-level soundbars might not deliver the same impact as premium models or a multi-channel speaker setup.

Not Perfect for Audio With Multiple Sound Elements

Virtual sound processing can’t replicate the pinpoint accuracy of physical ceiling, height, or surround speakers, like those used in systems with DTS:X or Dolby Atmos.

For example, while DTS Virtual:X adds depth and creates an immersive experience, it can struggle with fast-paced scenes—like chaotic car chases or intense battle sequences—where multiple sound effects need precise spatial placement to feel truly lifelike.

Music Performance Varies

While it does improve how certain tracks sound, audiophiles might prefer traditional stereo playback for simpler or acoustic music.

How Does DTS Virtual:X Compare to Other Audio Formats?

Alright, so now we know DTS Virtual:X delivers multidirectional sound without needing a room full of speakers.

But how does it stack up against other popular audio formats?

Here’s a breakdown:

DTS Virtual:X vs. Stereo Sound (Normal TV Speakers)

Stereo sound is one of the simplest audio formats, limited to two channels: left and right. While it’s known for delivering clear audio, it’s flat and it lacks depth and dimension.

Stereo sound works well for basic listening needs like podcasts or everyday TV shows, but it doesn’t create an engaging experience. Without directional or layered sound, it doesn’t immerse the listener.

Advantages of Stereo Sound:

Simpler and easier for basic listening needs.
Ideal for users who don’t prioritize surround effects.

Advantages of DTS Virtual:X:

Expands stereo sound into a more engaging, theater-like experience.
Makes even entry-level setups feel more premium.

DTS Virtual:X vs. Standard Surround Sound (5.1 or 7.2)

Standard surround sound systems, like 5.1 or 7.2 setups, are designed to create a horizontal surround effect using multiple speakers placed at the front, sides, and rear of the listener.

They’re great for getting a rich, enveloping sound experience within a horizontal plane, but these systems don’t have any height channels, so you won’t hear sounds coming from above.

On top of that, these types of setups require precise speaker placement to work effectively, making them less flexible for smaller or unconventional spaces.

Advantages of Standard Surround Sound:

Offers consistent and reliable horizontal surround sound.
Generally better suited for traditional home theater installations.

Advantages of DTS Virtual:X:

Adds height effects to audio without requiring extra speakers.
Works with existing 5.1 or 7.1 setups to enhance sound dimensions.
Eliminates the need for precise speaker placement, simplifying setup.

DTS Virtual:X vs. DTS:X and Dolby Atmos

Both DTS:X and Dolby Atmos are advanced 3D surround sound formats designed for high-end audio setups. They rely on physical speakers, including overhead or upward-firing units, to create precise audio placement in a defined 3D space.

These audio formats are staples in professional cinemas and high-end home theaters, because they can deliver a superior level of realism when paired with compatible hardware.

Unique Features of DTS:X

DTS:X focuses on sound object placement in a defined space. Each audio element is treated as an independent object and mapped to a specific location, allowing for pinpoint accuracy. This format is particularly popular because you can position speakers based on your listening position and make dynamic audio adjustments.

Unique Features of Dolby Atmos

Dolby Atmos takes a slightly different approach by emphasizing height channels and dynamic soundscapes. It uses metadata to map sounds within a 3D environment, often requiring ceiling or upward-firing speakers to achieve its iconic overhead effects.

The Advantages DTS Virtual:X Has Over Both

No need for ceiling or additional speakers, reducing hardware costs.
Works with single devices, making it accessible to more users.
Easier setup without requiring precise speaker placement.

Use Cases and Compatibility

DTS Virtual:X is a modern audio solution designed for small or unique spaces and for different lifestyles:

Small Apartments or Bedrooms: If your space is limited, DTS Virtual:X gives you a theater-like audio experience without cluttering your room with additional speakers or wires. A single soundbar can provide rich, directional sound that fills even a compact space.
Outdoor Setups: Using soundbars or outdoor speakers with DTS Virtual:X can transform backyard movie nights or gatherings by providing rich, surround-like sound, even in open spaces

One of the best features of DTS Virtual:X is its ability to work with different types of audio content. It doesn’t need special audio tracks, so it can be used with most formats, including:

Older DVDs and Blu-rays: It works with standard surround sound formats encoded in these discs.
Streaming Services: Services like Netflix, Disney+, and Hulu deliver content that benefits from DTS Virtual:X processing.
PC Gaming: DTS Virtual:X can enhance PC gaming audio. However, it typically requires specific software, such as the DTS Sound Unbound application, to be installed on the computer.

How to Enable DTS Virtual:X on Your Devices

Setting up DTS Virtual:X is simple and doesn’t take much time. It works best when using at least two speakers and sometimes you’ll have to turn it on. Here’s how to enable it and test its effects:

Enabling DTS Virtual:X on Soundbars and AV Receivers

Check Compatibility: First, confirm your device supports DTS Virtual:X. You should be able to find this information in the product manual, on the manufacturer’s website, or in the specifications listed in the settings menu.
