What Is DTS NEO 2.5?

The expertise of DTS Neo 2.5 (5) is predicated on the confirmed DTS Neo algorithm (4) and generates a three-dimensional sound expertise (1). Since human listening to charges sound indicators within the entrance space extra strongly than those who come from behind (2), the DTS-Neo algorithm provides two entrance loudspeakers (6) to offer the sound extra spaciousness (3). So, what’s DTS Neo 2.5?

DTS NEO 2.5 is a multi-channel encompass virtualization audio format proprietary from Samsung and DTS, that takes a stereophonic 2.0 audio stream and transforms it into encompass sound by way of the execution of an algorithm.

It’s present in Samsung gadgets because of their enterprise partnership with DTS.

DTS Neo 2.5 is an audio format with the identical channel division as with Dolby Digital, largely 5.1. DTS works with a continuing bitrate of 64 to 1536 kbit /s, on the DVD with 384 or 448 kbit /s, the sampling charge goes from 48 to 192 kHz at as much as 24 bits. With the DVD there’s compression, lossy, with an element of 4. With many DVD gamers, you may see a DTS image on the entrance panel, however these DVD gamers don’t have a DTS decoder in any respect.

Should you look carefully, the textual content “Digital Out” seems below the DTS. Because of this it’s important to use a receiver/amplifier with a DTS decoder to take pleasure in DTS format. The subwoofer channel goes from 20 to 80 Hertz. This format has existed since Could 1993.

The encompass sound is created by way of the algorithm, however it isn’t an actual encompass, that is the distinction. Most likely the issue is because of the truth that you utilize an optical connection, often, the optical connection has issues transferrin multi-channel streams (eg it doesn’t switch the DTS HD and grasp audio streams) and in any case, it shouldn’t be used, you will need to use HDMI to the TV-AVR connection.

In an effort to make the most of the DTS Neo, the consumer is suggested to take away the optical cable Toslink (proprietary customary from Toshiba) and put an HDMI instead.

Some customers reported that they’ve to show up the quantity additional than below Dolby Digital.

DTS Neo is, subsequently, one other multichannel audio format from DTS, direct competitors from Dolby. It consists of precisely the identical channels: 6, with two entrance left and proper audio system plus one other heart speaker, two rear left and proper audio system, and the LFE channel. The primary movie to undertake this format was Jurassic Park, in 1993.

DTS is obtained from an authentic PCM supply at 48 Khz and as much as 20 bits, and though it additionally compresses knowledge, the compression is much less, liberating information with a bit charge usually between 768kbps and its most of 1536kbps.

Dolby Digital Vs DTS Neo 2.5

The distinction between Dolby Digital and DTS NEO 2.5 is within the compression charge. Whereas Dolby Digital´s compression charge is larger, DTS has a decrease compression. Subsequently, DTS NEO 2.5 has extra constancy to the unique supply and the next bitrate.

DTS NEO 2.5 achieves mathematically higher empirical outcomes versus Dolby Digital in waveform evaluation with larger bitrate dimensions, leading to an analytically superior attribution of constancy.

Moreover, for humanly related audible variations, enough testing approaches are the double-blind take a look at, MUSHRA testing, or ABX. Grownup in people customary situations have difficulties to tell apart charges between 128 kbit /s and 192 kbit.

Empirical exams equivalent to waveform evaluation will most undoubtedly present variations within the output, however that does not imply the variations are audible for us in regular situations.

DTS has the next bitrate and sounds technically higher. However as customers don’t hear the distinction between 128 kbit / s and 192 kbit, they might be the identical in observe.

The output in DTS NEO 2.5 is on the market in Samsung gadgets and was developed on a partnership between Samsung and DTS. It filling extra cupboard space than the identical object in Dolby Digital because it compresses much less.

Lastly, we are able to say that the unique mixing of the soundtrack will set up crucial distinction within the high quality of the sound, with disregard of the audio format chosen afterwards for the audition.

For human audition in customary situations, there’s virtually no distinction between these methods. With the Devialet Gold or Silver, it’s potential to tell apart variations between output in laboratory testing situations that usually should not associated to typical consumer necessities of those merchandise.

Setting PCM or Bitstream settings doesn’t affect the choice Dolby Digital Vs DTS Neo 2.5, as a result of PCM and Bitstream are associated to the HDMI enter audio format.

For the reason that DVD solely has a restricted storage capability (single- layer 4.7 GB), the builders of DTS and Dolby had to make use of mathematical methods to compress the soundtrack from the quantity of information. The audio tracks on the brand new Blu-Rays are uncompressed as a result of massive storage capability of the disc. By way of measurement, the distinction between DTS and Dolby Digital is that DTS grants the sound bigger quantities of information and is, at the least in idea, a little bit bit higher in high quality than Dolby Digital. This can be demonstrated in lots of listening to exams (supplied the system is sweet).

The choice between stereo and 5.1 is extra essential: If in case you have the choice to decide on between Dolby Digital and DTS, usually just one soundtrack is recorded in 5.1 surrounds, the opposite in stereo or within the outdated Dolby Encompass technique. Then you’ll want to select the 5.1 variant. Whether or not it comes from Dolby or from DTS is much less essential right here. You can also make these settings within the audio setup of the inserted DVD.

Connecting To The AV Receiver

Join the DVD participant to the AV receiver utilizing a digital cable. This may be accomplished both through the audio-out connection or the Toslink (Toshiba Hyperlink cable format) connection.

In any case, AV receivers at all times have choices for utilizing one of many two variants. Nevertheless, there are some small variations in sound.

If in case you have wired all the things you want (usually known as by urgent the “Setup” on the distant) set the digital output to Dolby Digital or DTS earlier than the primary begin but within the setup of the DVD participant.


DTS is claimed to sound higher. It inherently makes use of the next knowledge charge, which may help this assertion. it additionally claims that DTS soundtracks are merely louder and combined with extra bass. Should you take a more in-depth take a look at the subject, it rapidly turns into clear that the blending of the soundtrack in origin is a way more essential issue for the sound high quality: and that may be good or unhealthy for each Dolby and DTS.
