Extended Knowledge: DTS VS AC3

DTS and AC3 are both codecs which are commonly used in different sound systems to produce high quality audio. Both these formats make use of different technologies in order to encode data and to improve the overall quality of the digital file. Both of these formats have their own advantages and disadvantages when it comes to the compatibility and specifications, and a comparison is required to be made in order to understand which one is to be used for what purpose so that the best audio results are obtained.

Comparing Chart Between DTS and AC3 from different aspects:


What is AC3/DTS
AC3 (Audio Coding) is nothing but Dolby Digital Audio Codec, which we commonly use these days on most of the audio devices. The audio compression for this format is lossy and Dolby Digital is the most commonly used version of this format which can house up to six sound channels together.
DTS is an audio codec which is a part of the Laser Disc, DVD and Blu-Ray specifications, which is a consumer version and used mainly at places where the loud sound is required. This format is used for large music systems and theatrical screenings and it is also a common distribution format for DVDs, for a simple reason that it is compatible with most of the supporting equipment.
Originally named as Dolby Stereo Digital till 1994, AC3 was initially called Dolby AC3 surround sound and later came to be known as Dolby Surround digital, which we now call as Dolby Digital.
The work on the development of DTS started in the year 1991, after which it entered the consumer market in 1996. It was suitable for a broad consumer spectrum for multimedia formats and pro audio products. Today DTS is one of the most common audio technology used in DVD players, theatrical screenings, digital media players, high-tech car audio systems and set-top box telecasting as well as Blu-ray discs.
AC3 is compatible with equipment used for HDTV broadcast, DVD playing, Blu-Ray discs, gaming consoles and home theaters.
DTS is used for decoding DVDs and on film prints, especially those which are used for big screen playing like movie theaters and large size projecting purposes.

When it comes to the sound output quality, both are almost similar to hear but technically, DTS is better, clearer and sharper than AC3. DTS is louder than AC3, without compromising on the sound clarity. AC3 uses Dialog Normalization, because of which the decoder decreases its volume by 4dB.

DTS, on the other hand, does not use any stabilizing, due to which will produce higher and clearer volume.
