My understanding is that zero crossing detection is also used in devices like digital audio players (when changing volume) and other digital systems where an instantaneous change in gain takes place that would produce an undesirable artifact. I'd add it to the article but I don't have reference nor experience. --Ktims 18:56, 31 March 2006 (UTC)[reply]

That would be the smart way to do it. I'm not sure if anyone actually does, though. — Omegatron 18:58, 31 March 2006 (UTC)[reply]

After doing a small amount of research, it looks like at least most of the general purpose audio codec ICs in use for this purpose support zero-crossing detection for volume control, and from the datasheets it looks pretty easy to implement, so I don't see why they wouldn't be. Incidentally, the Wolfson (iPod nano [1]) and TI (iAudio [2]) datasheets reek of plagiarism in that section...Anyway, after finding production ICs from 3 major players, barring dissent, I'll add it to the article. Here's a $0.95 DAC part from National that does it too [3]. --Ktims 23:05, 31 March 2006 (UTC)[reply]

Sounds good. ;-) — Omegatron 00:06, 1 April 2006 (UTC)[reply]

Page title

The page title should be "zero-crossing". This is a crossing of zero (that is, the x-axis), not a crossing that is equal to zero. "Zero" is an attributive noun here, not an adjective, and the hyphenation makes this clear. — Paul G (talk) 15:20, 13 October 2008 (UTC)[reply]

rambling disambiguation page

This article doesn't seem to have a topic. Maybe it could be split up, or turned into a disambig page. Bhny (talk) 17:16, 2 April 2014 (UTC)[reply]
