Talk:Surround sound

What about LPCM?
This artcle is a bit half baked. It should have LPCM listed for all audio because LPCM can do 1.0 to at least 7.1. Also Dolby Digital supports 1 to 5.1 channles so it sould also be listed under 3.0 and 4.0.

 * What does this even mean? Is this still even relevant? Is there a specific table or section that this information should be added to?  Please detail it here or add it to the article. Arbalest Mike (talk) 02:11, 25 January 2015 (UTC)

5.1 or 7.1?
Is there a big difference between 5.1 and 7.1 (e.g. for gaming), or ist the step from 5.1 to 7.1, compared with the step from stereo to 5.1, rather negliglible?

Its easy to write a lot about technical stuff. But some practical guidelines, altough they are not 100 percent objectiv, are really missing in the article. Technically everything is makeable, you can construct a 80.8-system. But what is the real improvement, what is meaningful for at home?

May be some notes about that in the article, altough not 100 percent objective, could enhance the practical value of the article.

Everything with senses and emotions is a bit subjectiv. But there are some general guidelines/perception/conception though. E.g. to hurt somebody and make somebody suffer is in generall felt as a bad thing - even when a masochist/sadist may feel it as a nice thing. Thats may be not the best example, but I hope you understand what I mean.

Anway, maybe its possible to enhance this article a bit in a practical way. There should be written what is senseful/meaningful, or better: what is the STANDARD: for HOME-CINEMA, for GAMING, for HOME-MUSIC. That helps to make some practical decisions, enhances the practical value of this article.

 * Thanks for the many meanings ;-) ---User1973 (talk) 16:09, 26 September 2008 (UTC)


 * You are suggesting the article contain a section that explains the purpose/intent/motivation/reason for each surround-sound format/technology in practical layman's terms, even if subjective. I agree with you on the need for that additional information. Arbalest Mike (talk) 02:11, 25 January 2015 (UTC)

Suggestion - addition of a table comparing technologies and formats
The section Types of Media and Technologies mention technologies with links to their respective pages but this article would be better (more comprehensive and consistent with other WP pages) if these were summarized in a table.

Some obvious columns would be:
 * 1) name
 * 2) company/inventor
 * 3) year introduced
 * 4) summary of a the main reason it was developed

The reason part being key, such as "added channel for this/that".

Other useful columns would be: Arbalest Mike (talk) 20:50, 24 January 2015 (UTC)
 * 1) current status of the technology (dominant, obsolete, still in use but not the dominant format)
 * 2) media requirements (type of disc) required for support
 * 3) equipment required for playback/decoding, conversion options, etc

3D audio
This article definitely needs more information on 3D surround formats such as Auro, Atmos, and DTS:X.Saycheesepleasedear (talk) 10:49, 14 June 2016 (UTC)

sound spatialization
"Sound spatialization" is redirected here, but the article at least begins with a slant that excludes sound spatialization. For example,"Its first application was in movie theaters" is false concerning sound spatialization, which was used by composers such as Berlioz before cinema even existed (and in non-Western cultures much earlier). Even concerning recorded music used in performance, spatialization was used by composers before 1940 in various avantgarde contexts. If the article incorporates spatialization, then it should it have an introduction that specifically excludes spatialization as used by composers and other sound artists?

Isn't "surround sound" actually simply a subcategory of sound spatialization? Would an article about the Presidents of the United States be entitled "Donald J Trump"?

Shouldn't there actually be two articles that cross-reference one another, rather than trying to awkwardly reconcile the irreconcilable?

Emoji on diagram?
since when did the ☺ emoji represent the center channel in the diagram under :Surround sound§ Channel notation: ? Slender (talk) 18:41, 2 February 2019 (UTC)

Added n.n.4 overhead surround channels
I have added information about Dolby Atmos 7.1.4 and 5.1.4 overhead surround speakers. This adds a third number to the surround numbering scheme. This numbering has become standard in the audio visual industry. Robert.Harker (talk) 20:28, 30 May 2019 (UTC)
