Dolby and DTS are two competing digital audio standards. One is a linear PCM standard, while the other uses a non-linear method of encoding sound waves to create its files. Which will be more popular in the future? Let’s find out!
The “linear pcm vs dolby digital ps5” is a question that has been present for a while. Dolby Digital and DTS are two different types of audio formats, but the difference between them is not always clear.

You must select if you want uncompressed or compressed audio output when comparing the sound quality of PCM and Dolby Digital. The first option provides plain stereo, whilst the second provides a variety of formatting choices as well as extra compression.
Because of the settings on current televisions, it’s fairly unusual to hear debates over whether Dolby Digital or PCM audio is better or worse. As a consequence, the purpose of this study is to look at where each of these two audio formats excels and where they fall short.
Linear PCM (native PCM) or Linear Pulse Code Modulation captures sound waves by measuring the real wave at each sample point. On the other hand, Dolby Digital and DTS are audio compression methods that offer surround sound codecs for 5.1, 6.1 (rare), and 7.1 configurations. They employ “perceptual” data reduction methods to eliminate unnecessary data from PCM signal output, preserving high quality sound. They conserve space on the disc (Blu-Ray and DVDs) or on streaming bandwidth for Netflix and other similar services.

What Is Linear PCM and How Does It Work?
Linear PCM is a digital representation of a recorded sound that is uncompressed. It contains all of the information included in the original audio signal, making it very massive and unsuitable for digital storage. It’s worth noting that Linear PCM is the same as LPCM and PCM.
One method for digitally encoding sampled analog signals is PCM. It’s the uncompressed form of most digital audio systems and chains that have been decoded and uncompressed before reaching the DAC.
Any processing that occurs generates a stream of PCM output data. To make it more engaging and richer, a conventional PCM audio stream may contain as many channels as required (it can have up to 10 channels).
What Is Dolby Atmos and How Does It Work?
Dolby Atmos is a surround sound technology developed by Dolby Labs that may be used to improve the sound quality of any movie or TV program. To make sounds more immersive than other formats, it employs a unique technique of coding spatial information.
Sound portions are not placed on particular channels or speakers by the sound mixer. Instead, it arranges them in three-dimensional areas (this is where the spatial coding process comes in).
Dolby Atmos is superior for surround sound than channel-based audio since it is object-based rather than channel-based. Of course, we’ll still need a speaker to present the findings.
Metadata is used to hold Dolby Atmos data, which is subsequently supplied through Blu-ray disc or streaming device. The spatial information is subsequently distributed by an AV processor or receiver dependent on the number of channels and speakers employed.
Dolby vs. Linear PCM
Pulse-code modulation (PCM) or the Dolby Digital codec may be used to digitally represent sampled analog signals. In computers, CDs, digital telephony, and other digital applications, PCM is the standard form of digital audio.
The Dolby audio codec format is a lossless audio codec. After the signal is received from the source, it is decoded, processed, and uncompressed in Dolby Digital. As a consequence, you’ll get a PCM stream with the proper number of channels, ready to send to the DAC.
Dolby compresses the PCM stream to fit more data into the same bandwidth, but not at the price of signal quality.
Dolby is a superior audio processing solution since you can choose how the audio is presented. However, you can only get the most out of this if you have a surround system that supports Dolby output in its entirety.
If you don’t have a surround system and want to hear the audio precisely as it was recorded, PCM is a better alternative. In PCM mode, your TV speakers may still provide an immersive sound.

Dolby vs. DTS vs. Linear PCM Ps4
PCM is the default audio setting on most gaming consoles. This is due to the fact that the audio is not compressed and is taken straight from the console. Most current sound systems handle 5.1 or 7.1 signals, which are supported by linear PCM.
While alternative audio formats (such as DTS) may be better for viewing movies or streaming your favorite Netflix series, compressed audio formats may decrease the sound quality of a demanding PS4 game.
When it comes to audio on the PlayStation 4, PCM is the best option. There is no extra processing required, and the audio is not compressed.
Both DTS and Dolby Digital are compressed codecs that need further processing. You’ll need a TOSLINK adaptor if you pick DTS as your default, but PCM will accept sound straight from your console.
Dolby vs. DTS vs. Linear PCM Ps5
The new PS5 supports PCM, Bitstream (DTS), and Dolby Digital audio codecs, providing a wide range of sound quality choices.
Linear PCM is the PlayStation 5’s default audio format and the best audio format for most users with a standard or even costly sound system or soundbar. It uses uncompressed audio data and does not have any audio delay.
Video game developers employ linear PCM audio in their games. So, if you want to play PS5 games the way they were meant to be played, utilize Linear PCM.
DTS is the second-best audio format for PS5 since it uses compressed audio data. However, there is a little delay in the audio creation since the PS5 compresses the audio data.
Dolby compresses audio data to improve audio quality. You may use this option to hear Dolby surround sound if your audio equipment supports it. The negative is that while playing games, it may create audio delays. It won’t make much of a difference if you’re playing on a PS5 at 30 frames per second.
Dolby vs. DTS vs. Linear PCM PS5 Headset
The new PS5 option provides you a 3D Audio experience if you use excellent headphones. You are given the linear PCM choice as a default.
Because these formats don’t function with built-in TV speakers yet, according to a recent Sony blog post, you’ll need a compatible headset to utilize them. This option works in the same way as the other PS5 audio formats, with Linear PCM being the optimal choice.
DTS vs. Linear PCM
Uncompressed digital audio supplied by optical, coaxial, or HDMI is known as linear PCM. It may be stereo or multichannel through HDMI. Because DTS utilizes lossy compression, this gives it the edge over it in the identical conditions.
What if you don’t have HDMI and just have coaxial or optical connections, but still want multi-channel surround sound? DTS is the greatest option in this circumstance.
From an audiophile’s standpoint, the Linear PCM vs. Dolby format dispute has some validity. The majority of consumers just want the best sound quality available from their equipment. That is why, in this kind of discussion, Dolby Digital will always come out on top. This is due to the fact that it has more channels.
PCM is the next best alternative if you don’t have access to those channels at home. You don’t have to worry about anything else if you utilize the automatic option on most TVs nowadays.
Dolby Digital and DTS are two types of audio codecs that are used to encode digital audio. Dolby Digital is a lossy codec, while DTS is an uncompressed codec. Linear PCM is a type of uncompressed audio codec. Reference: linear pcm audio.
