List of manufacturers

The list of manufacturers in the § Products section seems marginally beneficial to readers and I believe it has potential for misuse as a place for companies to promote their products (see WP:PROMO and WP:PRODUCT). Also there are few secondary sources used in this section, and the primary sources used give no objective indication to the notability of the manufacturer. I propose we delete the Products section as it is not worth trying to maintain it as an unbiased and all-inclusive list of all MADI card manufacturers. If there are no objections I will go ahead and do this. — Andrew Lorimer (talk) 08:56, 9 December 2019 (UTC)

Since there are no objections I have gone ahead and removed the section. — Andrew Lorimer (talk) 02:15, 13 December 2019 (UTC)

Embedded information question

Many of the newer “Engines” have MADI cards as an option such as the Klotz, DHD, Studer and SAS consoles. Most also embed information such as channel ID or label information that is driven by the manufacturers proprietary software. However this MADI information does not seem to transfer between manufacturers. I am told that Pro-Tel is the closest to a standard data format available. Can anyone elaborate on this? Has anyone managed to interface the Channel information between brands?

Uni-directional or Bi-directional?

I miss a fundamental information about this interface in this article: Is the MADI interface a Uni-directional interface, like AES/EBU and ADAT (one sender and one or more receivers), or is it a Bi-directional interface with multiple senders and multiple receivers? 84.20.36.138 (talk) 14:45, 19 July 2011 (UTC)

Last sentence of the lead now reads, "Like AES3 and ADAT Lightpipe, it is a unidirectional interface from one sender to one receiver." ~Kvng (talk) 20:02, 30 March 2020 (UTC)

Original publication date

My copy of AES10-2008 has notes in the forward referencing an original publication in September 1989. There is no indication of the differences between this original edition and AES10-1991. Any ideas? ~Kvng (talk) 19:12, 11 December 2019 (UTC)

MADI over twisted pair (AES-X213, "MADI TP")

The following is information about MADI TP that could be incorporated into the main article.

Since 2012 there has been an AES project to standardise MADI over twisted-pair cable (i.e. cat-5 ethernet cable). The project announcement is here (marked as "Posted: Friday, November 9, 2012"):

http://www.aes.org/standards/blog/2012/11/new-project-madi-x213

It appears that the effort is spearheaded by Marc Brunke. The following linked press release gives some details and background:

http://www.optocore.com/index.php/news-events/news/news-archive-2014/176-aes-to-extend-aes10-based-on-marc-brunke-s-madi-over-cat5-proposal

As of the meeting of the SC-02-02 working group, 2017-10-19, the AES-X213 project was rolled into a general effort to update the MADI specification (AES10-R):

"AES-X213: MADI over twisted-pair cabling: M Brunke is still working on the revised text. Task group SC-02-02-L and project AES-X213 to be closed, with the work moving into SC-02-02-M and AES10-R." Quoted from:

http://www.aes.org/standards/meetings/aes143-sc-02-02-report.cfm

As of July 2020, there are now products supporting "MADI TP" from multiple vendors. e.g.

RME: https://www.rme-audio.de/madi-router.html

DiGiCo: https://appsys.ch/en/products/digital-format-converters/mta-64-madi-tp-adapter

However there does not appear to be an official document from the AES describing MADI TP. — Preceding unsigned comment added by Ross bencina (talk • contribs) 15:52, 18 July 2020 (UTC)
