All wrong?

Subband coding is not the same as ADPCM. Is there any source that supports the content of this article? Or should I just flush it and put the scheme that James L. Flanagan invented? Dicklyon (talk) 18:15, 20 December 2008 (UTC)[reply]

I think it's closer to a real article now. I havne't found good support for my recollection that Flanagan invented it, but I think it's out there... Dicklyon (talk) 02:07, 21 December 2008 (UTC)[reply]

This article is absolutely useless.

Where's the details?! there's nothing that actually matters in this article at all. — Preceding unsigned comment added by Bumblebritches57 (talk • contribs) 23:57, 15 September 2014 (UTC)[reply]

SovalValtos, there are established authorities who could contribute to Wikipedia, but they won't. You know why? It's because Wikipedia has no peer review and allow anyone to make changes willy-nilly. Oh, sure, someone who's willing to bird-dog the subject can review the changes and revert, in part or in toto, but that's exactly what the established authorities don't want to be obliged to do. --MarkFilipak (talk) 01:41, 19 April 2015 (UTC)[reply]

This article is a joke

Why is this so damn short? It actually contains following information: - ADPCM is DPCM with a variable scale factor (yes, this is right) - ADPCM was developed in 1970... (might be correct... I don't know) - It is used in telephony instead of mLaw/ALaw to double the capacity of a phone line - There is a Subband ADPCM that uses two subbands

I'm so lucky that I already know, what ADPCM is. I switched to the english version because the german one doesn't look much better so far. Did the mankind already forget, what ADPCM is/was/will be?

- Where is the basic explaination how it works? A non-technician will not understand somewhat. That explaination don't need to be in-dept at developer/code level. - Where are the famous and frequently used IMA-ADPCM and MS-ADPCM? Never mentioned somewhere inside this article - Where is it used? (Telephony isn't the only purpose. It is used in many old computer games and many well-known gaming consoles, voice recorders, old cell phones, some cameras, anti-shock-buffers in portable CD players and some ancient digital storage media including CD-I) - There are some another ADPCM-based G.XXX-Standards not mentioned here.
