[edit] Industrial Noise Reduction

What about industrial noise reduction? -- 142.85.5.141 16:14, 4 June 2007

What about it? Is it audio? --Adoniscik (talk) 22:18, 2 February 2008 (UTC)

[edit] Split proposal

User:Binksternet‎ has started a process to split the article into audio noise reduction and image noise reduction; I've reversed the process for now, so we can talk about it first. Please support or oppose this proposal, and if you support say which new article to move the current article to (so we don't lose the history).

• oppose, at least weakly for now, not having heard any good idea how is this is going to make things better. Dicklyon 04:57, 3 September 2007 (UTC)

• support, naturally, since it's my idea. The problem I have with the basic Noise reduction page is that the audio noise reduction products and image noise reduction products available to the end user have nothing obvious in common. Photoshop and Dolby SR don't look at all alike to the end user. Trying to tie them together in the text of the page turned out to be very convoluted. I see the Siamese Twinning of both audio and image noise reduction as a barrier to clarity and a damper to future development of the two topics. Too many new products, methods and realizations regarding audio and regarding image are coming down the pike but these developments aren't common to users in the two camps. Image noise reduction technicians and audio noise reduction technicians are usually two completely different populations with little crossover. These two populations will come to the page, peruse for a few seconds, and turn away upon realizing that it isn't tightly focused on their concerns. I feel that future Wiki editors will look at this confusing admixture of topics and choose not to bring their value to the page. I'd much rather have two pages, each one catering to a specific group. Two pages will encourage further development.

Of course it's true the two topics have a commonality in their mathematical foundations. I would like to see the commonality emphasized in the digital signal processing and analog signal processing pages, or for there to be a new page called Noise reduction (signal processing) which details the approaches common to image and audio, digital and analog. An architect's viewpoint instead of a home dweller's viewpoint.

Personally, I have nothing to offer to the notional page Image noise reduction. I know precious little about image noise. I have a lot to add to Audio noise reduction in the way of phonograph record surface noise reduction methods, studio recording noise reduction equipment, broadcast noise reduction practices and software noise reduction methods and results. My background is all about audio production. Binksternet 05:50, 3 September 2007 (UTC)

• Oppose the change until the article is developed further. Not lagre enough for a split yet. --Blainster 07:38, 3 September 2007 (UTC)

• Oppose until the article becomes unwieldy. When the time comes, I suggest noise reduction (audio) and noise reduction (image)… and let's not forget noise reduction (video) (video denoising). I prefer parenthesized titles—they seems pretty common in disambiguation articles—so you can use the wp:pipe trick. --Adoniscik^{(t, c)} 23:16, 10 May 2008 (UTC)
