So, get geared to walk through my ultimate surround sound guide: From DTS to Dolby Atmos, every format explained! Everything that’s playing on your mind right now is on my blog.
Dolby Digital Plus vs Dolby Atmos vs Stereo: Which surround system is better?
Okay so, this is how we proceed. We will speak independently on each of the surround sounds and differentiate them based on a few criteria. But before I begin, my question to you is – Are you completely familiar with the concept of surround sound?
What is Surround Sound?
Surround sound is a contemporary method of refining the credibility and depth of audio effects by using multiple audio channels from diverse loudspeakers that surround the listener. The mechanism of audio from all angles is generated by placing additional speakers strategically. This 360 degrees of sound representation can splendidly create a sound sensation from all directions.
The popularity of home cinema has risen the need for surround systems as well. The most common types of surround sound channels are – 5.1 and 7.1. This mainly refers to the number of speakers required to enrich the audio quality at home.
In the case of a 5.1 sound system, you will have five main audio spectrum channels and one subwoofer. Each of the sound channels is discrete so that you can place it anywhere in the room. This is one of the most common and inexpensive configurations for home theatre systems.
Speaking about the 7.1 sound system, it comprises eight speakers. Compared to the 5.1 channel, this one has two additional speakers. The placement of the 7.1 configurations ensures a more reinforced sound quality. So, they are more recommended for large rooms.
Dolby Digital – What do you need to know about the spatial audio format?
Formerly known as Dolby AC-3, this sound encoding system can dwindle the substantial amount of data required to generate a high-quality sound. The Dolby Digital technology is designed for online streaming, DVDs, TV broadcast, Blu-ray disc and more.
The smart automation imparts a speedy transfer for audio signals, which may have one or more surround channels. Almost every home theatre system has a built-in Dolby Digital decoder. So, the surround sound marketplace is well dominated by Dolby.
The sound effect of Dolby Digital is not just impactful but also realistic. The technology convincingly brings out all the emotions. You are sure to feel like you are in a cinema. The only downside of the audio technology is the high chances of deterioration in the audio and video quality. The reason behind this degradation is the high compression level.
Advantages of Dolby Digital Surround Sound
- Dolby Digital can certainly deliver cinema feels at home.
- The technology has easy access to all software.
- You can expect accurate transfers from the channels.
- The Dolby Digital technology is capable of operating at a low bit rate.
Dolby Digital Plus- What do you need to know about the spatial audio format?
Dolby Digital Plus is nothing but an improved version of Dolby Digital audio technology. The key difference between both surround sound formats is the number of channels. The Dolby Digital technology can support only six channels. On the contrary, Dolby Digital Plus technology can efficiently support upto eight channels. Because of this, the latter can deliver high definition audio. It is capable of compressing large files without compromising on sound quality. So, you can expect a more realistic sound interface.
Advantages of Dolby Digital Plus Surround Sound
- In addition to the standard channels, Dolby Digital Plus is compatible with HDMI as well.
- The advanced technology delivers high-resolution sound along with retaining the original audio quality.
- Dolby Digital Plus can support a wide range of data.
- The progressive technology is also backwards compatible.
Dolby Atmos – What do you need to know about the spatial audio format?
Dolby Atmos surround sound can gracefully bring out a revolutionary change in cinema audio. The technology is a notch higher in providing a 3D surround sound. Every channel comes with a lot of detailing and provides a three-dimensional sound interface. So, this format can deliver a more realistic sound ever.
Dolby Atmos changes the game completely by adding custom-built upward speakers for an exclusive sound experience. How does this work? With the help of the system (placed on the top), the technology creates a high-defined dramatic sound by bouncing back the audio to the listener. So yes, Dobby sound and Dolby Atmos aren’t the same.
The smart technology is compatible with all high-resolution systems – Television, laptop, tablets and more. The major downside of this sound technique is that the overhead sound signal requires extensive content-encoding. Besides that, setting up the system can get a bit complicated.
Advantages of Dolby Atmos Surround Sound
- The surround sound provides overhead effects as well.
- The precise placement of the system helps the user achieve an exact sound.
- The system is compatible with HDMI cables and Blu-ray disc players.
- Dolby Atmos supports online streaming efficiently.
DTS – What do you need to know about the spatial audio format?
Originally known as Digital Theatre System, DTS was established to deliver a supreme sound effect with the help of surround sound channels and subwoofers. Unlike Dolby Atmos, DTS:X does not need a ceiling speaker setup to derive an enhanced sound effect.
Dolby Digital and DTS have been competing aggressively with each other. Both technologies can deliver a phenomenal sound quality. However, the way to the end result is remarkably different.
Dolby Digital v/s DTS: What’s the exact difference? For the Blu-ray discs, the former compresses 5.1 digital sound to a bit rate of 640 kilobits per second. Whereas for DVDs, the bit rate is lower than that- 448 kilobits per second.
Speaking about DTS, the technology can efficiently support high bit rates and is less compressed. It can support about 1.5 megabits per second for Blu-ray discs, and for DVDs, it can support 768 kilobits per second.
Let me now explain this to you in layman’s language. Less compression means an explicit audio result. So, you can hear closer to what was primitively planned. Based on the compression criteria, DTS scores an edge over Dolby Digital.
Advantages of DTS Surround Sound
- DTS promises a truer cinematic experience.
- The technique is capable of encoding sound at high bit rates.
- DTS is adaptable to change.
- The technology makes use of personal software. Therefore, the end results are magnificent.
Stereo Sound – What do you need to know about the spatial audio format?
The Stereo sound was the first ever to bring a significant change in the world of a surround system. The sublime technologies like Dolby Atmos and Dolby Digital Plus came into existence by following the routes of the evergreen Dolby Stereo. The system has channels on the left and right to create a high-quality sound.
Today, the Stereo sound format may fall short because of the fewer sound channels. Therefore, the technology may fail to provide a room-filling sound.
Advantages of Stereo Sound
- It is one of the cheapest surround sound providers.
- The system is sufficient to deliver a pleasant audio experience.
- It can skillfully prevent phase interference between speakers.
