Is there any known information about the Sampling Rate for 22.2? (Current example: CD-44,100 hertz or 44.1 khz)— Preceding unsigned comment added by 74.211.7.12 ( talk) 18:34, 21 April 2007 (UTC)
so then you could fit about 40 hours on a 1tb hard drive? and you can fit 12 hours of 128 kbit mp3s on a cd. i wonder how they would record that? with 24 microphones? thats just insane to have 24 speakers. Amddude ( talk) 07:39, 20 April 2008 (UTC)
I think the speaker setup section should include an illustration to give an idea as to what all 24 of these speaker's set up would look like —Preceding unsigned comment added by 209.81.124.118 ( talk) 00:27, 23 June 2008 (UTC)
<!----------------------------------------------------- Section could be replaced by a single diagram. The figure "(5)Audio system configuration" on the NHK Web page referenced above would be excellent. I e-mailed NHK to ask permission to use it, but they said no. Have included <ref> to figure instead. ------------------------------------------------------->
...but why isn't it 24.2 if it uses 24 speakers? 71.233.250.241 ( talk) 21:43, 9 January 2009 (UTC)
The DIAGRAM actually shows 24 discrete speakers and 2 LFE speakers. Eleven in front, five on each side, one in the ceiling ("top"), and two on the back wall. 11 + 5 + 5 + 1 + 2 = 24 So... either the nomenclature (22.2) is incorrect, or the diagram is incorrect. Gil gosseyn ( talk) 08:47, 6 January 2015 (UTC)
The Diagram is incorrect. The Bottom layer does not have side speakers but only 3 front speakers(L, C & R). Also, Dolby 5.1 layout is not correct because the rear speakers should be placed on +-60 degree from the back, not on sides. I will recreate the figures later. 松浦知也 ( talk) 16:03, 17 July 2020 (UTC)
Where did the current channel table come from? According to this link the channel names, abbreviations, and order are completely different. The same types of channels are there, but with different names and orders.

Thanks HairyWombat , I see now that there's actually a reference to SMPTE ST 2036-2:2008. I checked that document and the table on the wiki is correct according to the SMPTE standard. I'll leave it as that as that is a more authoritative (and newer) reference source (--cvanwink). — Preceding unsigned comment added by 192.150.10.201 ( talk) 04:46, 10 August 2012 (UTC)
External link to NHK source paper is broken. Has the document moved? — Preceding unsigned comment added by 195.70.5.235 ( talk) 10:03, 31 October 2013 (UTC)
The article describes the speaker layout as having 10 listener plane channels, 9 overhead channels, 3 bottom channels and 2 LFE channels. However, the diagram shows 26 speakers: it seems it has added two extra bottom plane channels on the sides. Perhaps this should be fixed? -- James ( talk) 08:58, 16 November 2013 (UTC)
what is it used for? It is not mentioned in the article. :-( -- RokerHRO ( talk) 22:40, 23 April 2014 (UTC)
From the 10.2 Wiki - "The ".2" in 10.2 refers to the fact that an additional Low Frequency Effects channel is added, not just a second subwoofer, to enhance the sense of envelopment. All bass from the left channels are directed to a left LFE channel while right channel bass is directed to the right LFE channel."
Which seems kind of obvious - except that not all 2 subwoofer set-ups are used in stereo. So instead of a mono subwoofer signal being split into dual-mono signals for left and right, there are 2 distinct LF effect channels- one for left and one for right. I am unclear if this is advantageous or not, as I understand bass below approx. 80Hz to be omni-directional, with only the upper-harmonics being directional (in theory being covered by the non LFE channels). Hopefully someone with a better understanding can follow up. Skeen267 ( talk) 00:39, 21 April 2021 (UTC)
There does seem to be some confusion here about placement and type. I had understood that this format had both top and separately bottom sound distribution, and that these could be but were not necessarily multiple speaker units for above (and below). Though admittedly this would affect the numbers given, which I had also thought was the original point of this nomenclature. Can we get some authority on this?
