Question

does matrix decoding involve utilizing 2 stereo channels being "mirrored" and separating offsets on the other channels? (unsigned comment from anon) —Preceding unsigned comment added by 69.209.157.150 (talk) 13:41, 4 Febuary 2006 (UTC)

No. For example, UHJ decoding produces W, X, Y channels from Left, Right. Martin.leese 22:33, 6 January 2007 (UTC)[reply]

Merging with Matrix (sound recording)

The two pages are complementary in that one should describe encoding and the other decoding. (Although that doesn't seem to be the way they have been written.) I don't have strong views on merging, but feel strongly that the merged article, if there be one, should retain the "2:4" notation used in Matrix decoder.

I am of the opinion that there should be two pages, namely 'audio matrix decoding' (not 'decoder') and 'audio matrix encoding', each of which should have proper links to the other. References to applications for the technology (such as sound recording) should appear on the page(s). Note that pages already exist for encoder and decoder. Novatek 19:56, 20 March 2007 (UTC)[reply]

See also Discretedored?

Is Discretedored even a word? I did a google search and the only page it returns is this wiki entry, not even one other suggestion. Possible mistype of some form of audio encoding or strange vandalism? —Preceding unsigned comment added by 69.241.82.132 (talk) 09:19, 4 January 2008 (UTC)[reply]

Dolby Surround and Pro Logic should be the same

The Dolby Surround matrix and the Dolby Pro Logic matrix should be the same. I don't recall which of the two presented is the correct one, and so cannot fix the article. But they should definately be the same matrix; one of them is definately wrong. HairyWombat (talk) 13:50, 17 April 2009 (UTC)[reply]

I think the second set of equations is correct (i.e. sqrt(1/2)). Dolby Laboratories received US Patent 5,291,557 (http://www.google.com/patents?vid=USPAT5291557), which has this equation in claim 6. —Preceding unsigned comment added by Beavioso (talk • contribs) 23:05, 12 May 2009 (UTC)[reply]

Why ENcoding matricies in Matrix DEcoder?

This article is titled Matrix DEcoder, and yet it contains little except the ENcoding matricies for the various schemes. Surely it should contain the DEcoding matricies. I have no desire to correct this; if I had my way the whole article would be deleted as it contains only information better expressed elsewhere, and I do not see what purpose it serves.
