![]() This causes the decoder to decrease the volume by 4dB and that accounts for the quieter sounds of AC3 compared to DTS. This is due to the fact that the latter uses a bit of metadata known as Dialog Normalization. The same people say that DTS is clearer and sharper compared to AC3.ĭTS is also generally louder than AC3 or Dolby sound.

If you need to reproduce the entire surround sound signal on an AC3 file, then you require a supported playback device such as a DVD player which is connected to a Dolby Digital supporting home-theatre amplifier. It makes for a total bitrate of 384 kbps. What makes AC3 sought after is the fact it increases fidelity compared to its previous format of surround sound standard, the Pro-Logic. The file format was created by Dolby Labs with the intention of using it in Dolby Digital Audio on DVDs, the much so popular Blu-ray as well as other digital video formats. That is enough about DTS and now let’s explain what AC3 is.ĪC3, which is short for Audio Coding 3, is a file extension for files that have surround sound and are used on DVDs. This is what allows backward compatibility. In the case that a decoder does understand it, it can modify it with respect to the instructions that are contained in the extension stream. The core stream, in turn, can be later decoded with the aid of any DTS decoder, regardless of whether it understands the new variant or not. The extension stream incorporates the additional data that is needed for the new variant in use. The variants are basically based on the core and extension philosophy of DTS, whereby an extension stream augments a core DTS data stream. The DTS variants available today include versions that can support up to seven primary audio channels in addition to one LFE channel (or DTS ES). ![]() Currently known as the Datasat Digital Entertainment, it has announced a range of high-end audio processing products.

Moreover, there are situations and places where only some can be used as others have certain drawbacks. There are many different types of sound systems, each with some special characteristics that make them better adapted or suited for certain tasks as opposed to others. For those of you who have no clue what we are talking about, let us just say that the topic refers to sound systems.
