Document link[edit]

I believe one of the two links ("original") for citation [1] is wrong, it's the I2C spec not I2S, and it differs from the other link in the citation which is "archived from the original" — Preceding unsigned comment added by 69.117.134.191 (talk) 19:57, 8 June 2020 (UTC)[reply]

That's a problem with NXP's website, not us. The URL http://www.nxp.com/acrobat_download/various/I2SBUS.pdf now redirects to https://www.nxp.com/docs/en/user-guide/UM10204.pdf which is an I2C spec. — Omegatron (talk) 18:41, 16 September 2020 (UTC)[reply]

Timing Diagram[edit]

I think the timing diagram is wrong. Check the datasheet for Pilips 1334A for instance, they have one more clock cycle before next data. — Preceding unsigned comment added by Lboclboc (talk • contribs) 16:16, 5 December 2020 (UTC)[reply]

That's just the least significant bit of the previous data. In that datasheet, the numbers above the clock wave correspond to the bit numbers of the databits that are driven at the next high-to-low transition of the clock. So the databit corresponding to ">= 8" is slightly to the right of the high period marked ">= 8" and databit 1 (MSB) is slightly to the right of the high period marked 1. Personally, if I had drawn that diagram, I'd have put the numbers such that the center line of the number lies on the low-to-high transition, or put differently, smack in the middle between high-to-low transitions. I think that diagram is slightly confusing. Digital Brains (talk) 16:34, 5 December 2020 (UTC)[reply]

Audio Interconnect[edit]

The audio interconnect section needs more references. At the very minimum the section needs one reference for each manufacturer for the connector type they are using. Ideally the sources would contain technical details about the pinout used, date when the connector/pinout was introduced, and position of the company regarding standardisation. Other acceptable sources might include instruction manuals of the equipment, or publications by people who do reverse engineering of audio equipment. I did some quick googling on the subject. There seems to be a comparison table available from minidsp.com. It is unclear how this information was gathered or who gathered the information. It also looks more like an ongoing study rather than a polished document containing verified information. I don't think it is suitable as a source. However, it might be useful as a starting point for locating more authoritative information. Cyberixae (talk) 17:53, 9 October 2022 (UTC)[reply]
