Nomenclature?

The word pulse in the term Pulse Width Modulation is somewhat confusing, as there appear to be no "pulses" per se anywhere to be found.

I believe this should read 'Pulse Code Modulation'. Please confirm. — Preceding unsigned comment added by Ktims (talk • contribs) 09:37, 21 June 2006‎ (UTC)[reply]

High Definition Media

From what I have read, many Blu-ray movies have PCM soundtracks. But HD DVD? I don't think ANY of my HD DVD movies have a PCM soundtrack. I am not sure "many" applies to HD DVD PCM soundtracks. — Preceding unsigned comment added by 75.71.201.149 (talk) 12:05, 25 October 2007‎ (UTC)[reply]

32-bit

Doorknob747 apparently would like us to include information on 32-bit PCM. I'm reverting the restoration of Linear pulse-code modulation (which I had merged into this articl) but have added the material that the article was apparently revived for. I know there is 32-bit floating-point audio. I don't know that 32-bit PCM is a real thing and the reference supplied is not particularly reassuring. ~KvnG 18:44, 28 March 2014 (UTC)[reply]

The blog/discussion board reference is not good enough to state this as a fact. I see no 32-bit PCM in professional audio. Mac OS X uses to 32-bit floating-point linear PCM, but floating-point is not the same as 32 actual bits. Binksternet (talk) 19:34, 28 March 2014 (UTC)[reply]
look this up on internet PCM_S32BE. Also if u were to install wave surfer and use it to convert a audio sample there is a option to convert it to Lin32. Also, VLC media player reads Linear 32-bit audio.Doorknob747 00:42, 29 March 2014 (UTC)

These sources are not good enough. None of them are mainstream authors. Binksternet (talk) 03:36, 29 March 2014 (UTC)[reply]
[1] is definitely a reliable source but is not particularly specific. [2] forum posts are not considered reliable. [3] and [4] are talking about floating point audio, not PCM. [5] isn't bringing up anything useful for me. ~KvnG 12:45, 31 March 2014 (UTC)[reply]
