What's The Difference Between AC3 5.1 And DTS 5.1?

I can clearly see why uncompressed HD sound is in another league but it seems to me that compressed AC3 and DTS sounds nearly the same. Of course those formats deliver a complete 5.1 mix. Mixing happens when a movie is made and the soundtrack is mastered as multichannel PCM.

The reduction in data represents the removal of objective and perceptual redundancies that are in the original PCM audio signal. Yes No Thank you for your rating. Center Channel 4.

As for volume, Dolby uses a bit of metadata called Dialog Normalization, which usually telles the decoder to lower the volume by 4dB. DTS surround sound is an alternate AC 5.1 surround sound which DTS states is not as compressed as Dolby Digital. An AC3 is a 5.1 file, but it is compressed. While cable networks don't have this mandate, they will just go along to ensure compatibility with the receiver market.

When the DTS soundtrack is encoded at the highest bit-rate of 1.5 Mbits/s defined by this DTS standard, DTS claims that it is capable of achieving indistinguishable audio fidelity from its Both companies obviously think that their product is better. I'm afraid I cannot agree with these statements. If you were to listen to the AC3 encoded file, you wouldn't like what you heard.I know full well what an AC3 is!

forgive my layman. You will find these logos on the front of many receivers and DVD players alike. Here are some facts. This audio format offers any number of dedicated channels up to five main channels and one low frequency effect channel.

Surround sound channels are encoded as either "discrete" channels or as "matrixed" channels, although the Dolby Digital EX format uses a combination of both. It is essentially Dolby Digital. jimlongo08-12-2011, 03:33 PMYou're probably referring to 2 channel dolby surround (matrixed LCRS) versus 5.1 discrete. Why?

Among the most confusing elements of home theater, the subject of audio decoding methods stands the tallest. http://forum.videohelp.com/threads/328790-Difference-Between-DTS-5-1-Dolby-Digital-AC3-5-1 As much as I hate streaming/downloads in favor of blu-ray or better, I think streaming will only get more popular, if it isn't already. Use dts if you prefer audio. When a client asks for 5.1 discrete they are asking for a digital copy of the original 5.1 sound Mix NOT an AC3, matrixed or anything such as that.

Dolby Digital surround sound is compressed which allows more audio information to fit on a DVD disc. his comment is here Posts: 1,296 What is the difference between Dolby DIGITAL & dts? Usually one can simply disable DRC on the receiver, and raise the volume, to make it sound very close to the DTS track. At these reduced bit rates, one cannot speak of perceptual audio transparency for either format, yet these represent distinct differences when comparing Dolby vs.

Dolby Digital soundtracks are optically recorded on the 35mm film strip itself using sequential data blocks placed between sprocket holes as shown in the diagram below, at a fixed reduced raw Recommends: Kiva.org - Loans that change lives. minister08-12-2011, 06:13 PMAC3 is still discreet though as each channel is separate. this contact form If you were to listen to the AC3 encoded file, you wouldn't like what you heard.

And AC3 or DTS or Dolby E does not deliver a "true" or "complete" 5.1 mix from the dub stage because it has to be decoded. DTS formats. Regardless, I certainly recommend getting DTS compatible equipment for both your DVD player and your receiver since the cost is minimal.

The 6 original "discrete" files (LCRLsRsLFE) do not need a decoder to unfold to anything because they are "discrete".

Thus, while it is objectively possible to compare the resultant sound quality for the same audio format encoded at different bit rates, and therefore, to determine whether the same format in Clarify your definition of what discrete means. lexaudio08-15-2011, 12:14 PMThen interleave is not discrete mr.armadillo08-15-2011, 02:47 PMYou're funny. Most if not all Dolby TrueHD blu-rays have a DD track that is interleaved in the same stream that decoders can also extract, but it's not a "core" in that the

Having the Dolby Digital soundtrack direct on the film means that audio content is susceptible to physical damage due to film aging and mishandling. Right Rear 6. navigate here DTS debate, DTS people argue that they are after 'sonic perfection, not space consumption' - hence the use of a higher bit rate and lower compression.
