Talk:Sony Dynamic Digital Sound

Need specific dates/cites on when SDDS started to fall from common use

I deleted the assertion that SDDS was in common use until the switch to digital cinema. The first year in which most American moviegoers had access to at least one digital screen in their metro area was 2008, and the first year when the majority of screens were digital was 2011. 2013 was the first year when studios started skipping film releases for major titles. SDDS was dead long before this - Sony stopped making new readers in 2002 and some studios stopped supporting the format entirely at that time. By 2003 even Sony itself was only putting SDDS tracks on its biggest few releases each year and by 2005 seeing an SDDS track on anything was unusual.

It wasn't digital cinema that killed SDDS and the article could do a better job of explaining what did and when it happened. Predestiprestidigitation (talk) 17:20, 20 March 2022 (UTC)

Reworked

I've moved the list of films to it's own article. I also moved the "8 channels is wierd" comments. SDDS is emulating the 70 mm magnetic format(s) which used 5 stage channels. I've also removed the Bluray speculation. Megapixie 03:34, 3 December 2005 (UTC)

Use of "to date"

I'm new to the backstage side of Wikipedia, but shouldn't phrases like "Out of the 1,400 plus films mixed in SDDS, only 97 of them to date have been mixed to support the full 8 channels" be given a date instead of the using the ambiguous "to date"? MRJayMach (talk) 09:34, 13 August 2008 (UTC)

effective bitrate

i talked to a tech with moderate knowledge of equipment (or maybe a manager). the total bitrate sounds familiar (i recalled 2-3mbit), but i thought i read somewhere that the usable bitrate was lower than that (somewhere around 700kbps) after the redundant/parity/ECC data was stripped away (because the edge of the film got destroyed the quickest/easiest). does this ring a bell with anyone?

this study pushes me towards 700kbps as it says a MiniDisc, which uses "5:1" compressed ATRAC, is about 300kbps for 2 channels of audio. 5 channels is 750, plus the sub. it MIGHT use "similar audio" between channels (joint-stereo/intensity stereo in the MP3 world). again, that 700kbps is "what comes to mind," not a number a stand by. some clairification on this subject would be nice.

Still the best

Wow I didn't realize how old SDDS was, it started back in 1993, almost 20 years ago. I wonder why 10.2 or something similar is not catching on. Is it presumable that 7.1 is "enough" and or is it just not practical to mix over 10 channels? Daniel Christensen (talk) 01:20, 14 April 2010 (UTC)

Technical

In the section 'Technical' there is the sentence "The format carries up to 8 channels of discrete digital sound encoded using Sony's ATRAC codec ...". Is it possible that in fact is meant "The format carries up to 8 channels of Dynamic Digital Sound (DDS) encoded using Sony's ATRAC codec ..." ? Bob.v.R (talk) 04:51, 14 January 2019 (UTC)

I see now that I changed it at June 21st, 2019. - Bob.v.R (talk) 19:59, 30 November 2019 (UTC)
