Wood

What is the kind of wood that makes wooden planks? Informationappeared (talk) 03:40, 4 December 2024 (UTC)[reply]

There are probably hundreds. Common ones are pine, maple, cherry, walnut, teak, oak, kiaat and many more. It will vary from country to country. The are 2 main categories - hardwoods and softwoods. 196.50.199.218 (talk) 05:03, 4 December 2024 (UTC)[reply]

The lumber article may be of interest. 196.50.199.218 (talk) 05:06, 4 December 2024 (UTC)[reply]

In Europe, nearly all floorboards and general-purpose wood sold in DIY stores is spruce, mostly Norwegian spruce or Sitka spruce - it's known in the timber trade as "white deal", although actually a very pale yellow colour. Scots pine or "red deal" is sometimes also used and can be distinguished by its prominent grain and darker colour (pine kitchen furniture was popular in the 1980s). Larch is used for fence panels, pallets and other purposes where a smooth finish is not required. Alansplodge (talk) 21:30, 4 December 2024 (UTC)[reply]

Besides spruce, beech is also popular for furniture in Europe. The really heavy furniture designed to last for centuries (i.e., mostly antique by now) is usually made of oak. PiusImpavidus (talk) 11:46, 5 December 2024 (UTC)[reply]

It appears the user is writing a new draft article for planks, but Wikipedia already has plank (wood). 64.53.18.252 (talk) 22:21, 4 December 2024 (UTC)[reply]

Stereo balance/phase correlation meter in surround sound

I've finally implemented stereo balance (level difference between left and right channels) and phase correlation (level difference between mid and side representations) metering into my own peakmeter project so I'm wondering, are correlogram/pan meters still useful for surround sound? Basically if you put something like this into my own peakmeter, there are 2 phase correlation and stereo balance meters for each pair in 5.1 and quadraphonic sound when shown. 2001:448A:3070:D641:A0A3:AF2:596E:8A96 (talk) 23:49, 4 December 2024 (UTC)[reply]
