Nomenclature?[edit]

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[edit]

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]

Floating point PCM[edit]

PCM is usually assumed to be integers, but also includes floating point samples. Is the definition basically "samples encoded as binary"? So it could use some other encoding scheme like Unum (number format) and still be PCM? https://www.kvraudio.com/forum/viewtopic.php?t=520701 — Omegatron (talk) 16:59, 6 June 2020 (UTC)[reply]

LPCM[edit]

Could someone who understands this please provide a more detailed explanation?
Perhaps a diagram - the sine wave diagram is very nice but I am having trouble relating this to LPCM... — Preceding unsigned comment added by 207.81.124.137 (talk) 02:45, 12 January 2022 (UTC)[reply]
