Talk:CX (noise reduction)

Titles
Is there any more information on listst of CX encoded albums.

(reply to above) I haven't found any but I remember a CBS Masterworks title, "Phases of the Moon" (Chinese classical music) which was released in CX and normal versions. I bought it, thought it sounded funny compared to the non-CX version I'd borrowed from the library, and returned it. --ewilen

Here's the link to the AES paper outlining the changes to CX for LD: http://www.aes.org/e-lib/browse.cfm?elib=11824 I'm not sure how to make the title of the reference into the link. Ty Chamberlain (talk) 14:55, 14 July 2010 (UTC)

How does it work?
The article contains zero technical information. Was there any additional information on the disc or did it work just like the dolby system for compact cassettes? --Moritzgedig (talk) 11:45, 21 October 2017 (UTC)

Possible ToDos
A list of possible ToDos:


 * Add datasheets for (and photos of) the Telefunken TFK U2141B and the Hitachi HA12043 and HA12044 dedicated integrated circuits, perhaps even add relevant excerpts of circuit diagrams. Ideally including links to PDF versions of those datasheets.
 * Expand the functional description for more details and add more technical specs of the compander characteristics.
 * Add block diagrams, frequency and spectral curves, oscillograms.
 * As there have been only a limited number of CX encoded vinyl disk we should aim for a complete list even if we don't have articles for all of them. Same goes for the list of encoders: If you are aware of CX encoders not yet listed, please add them (ideally with a reference proving its existence)
 * Provide links to digitized CX-encoded vinyl recordings played back with and without CX 14, perhaps in comparison to a digitized non-CX-encoded vinyl disk of the same recording. Also, a file of a non-CX-encoded vinyl disk still played back through a CX decoder could have some illustrative value for readers/listeners.
