Différence entre le son 5.1 et le DTS

Solved/Closed

Hello,

I would like to know the difference between 5.1 sound and DTS.

Because when I watch DVDs, the audio menu gives me the option to choose either 5.1 sound or DTS.

Which one should I choose for better sound or perhaps more sound effects?

Thanks in advance.

a bit of info even if resolved:
initially, all sound was in mono or 1.0 (for a single channel). then it modernized and we could have sound in 2.0 to achieve stereo (left and right channels). later, 4.0 appeared, equivalent to 2.0 x2 to provide some depth and thus better sound distribution. then the first Dolby technologies arrived like Pro Logic, Dolby SR, Dolby SRS... which spatialized stereo sound and simulated multichannel with a base of front left, front right, center, and 2 mono surround channels. then it improved further, Dolby Pro Logic 2 came along and replaced mono spatialized surround with two distinct channels. then the first Dolby Digital 5.1 appeared with digital sound specially made in DD 5.1 to achieve perfectly multichannel sound. but then, some Dolby employees had an idea to compress Dolby less to make it better. However, Dolby didn't like it and basically thanked them. later, they created the DTS logo in France, which is largely based on the same idea as Dolby but with different encoding and less compression, resulting in better sound in general than the best Dolby in the same range (I'm not talking about HD sound from Blu-rays, for example). thus competition was born, and those who love good sound prefer DTS for being more dynamic and responsive.
DTS, like Dolby, is often associated with either 2.0 or 5.1, but there are many DVD films and music that have Dolby Digital Surround sound providing a central channel at the back, like in Harry Potter or Star Wars, or DTS ES Matrix or DTS ES Discrete, also providing sound with a central channel at the back, as found in 007 Die Another Day for example.

for high definition sounds, in addition to the sounds mentioned above, there are Dolby High Definition or Dolby Digital Plus, Dolby True HD, DTS High Definition, and DTS Master Audio. The high definition/plus versions provide better sound than "classic" Dolby or DTS, and the True HD or Master Audio delivers studio quality without compression with sound significantly better in DTS (which is why we see more of it). Among the indicated HD sounds, you can find from 1.0 to 7.1, the majority unfortunately being 5.1. Otherwise, there is also PCM, which is also uncompressed and occasionally better than DTS MA but sometimes not, it all depends on the ear

anyway, one must not confuse 5.1 and DTS or Dolby or others. 5.1 indicates the number of speakers (3 in front, 2 at the back, and the .1 corresponds to the subwoofer). Dolby or DTS indicates the type of audio encoding.

there you go, hoping I helped despite everything, happy holidays!

Thank you for this well-presented tutorial.
It is not easy to navigate through all these standards.

It enriches my knowledge, which is not extensive in the field of sound.

Good evening Frédéric,
I just bought an HD Blu-Ray DVD player so that I can watch the Blu-Ray DVD GOMIRRA by Matteo Garrone in 5.1 DTS-HD Master Audio with MPEG4/AVC encoding. Unfortunately, when I put the DVD in the player, it indicates that it cannot be played. Do you think I have the possibility to view this DVD with my new player, please?
