I searched for the Netflix "Secondary Audio Delivery Specification": does that page contain the requirements, where do the file format, channel order, loudness and peak numbers actually live, and can I still read them?

The Secondary Audio Delivery Specification page (API updated_at 2024-03-18) is a one-sentence pointer to "Localization, Accessibility, and Dubbing Branded Delivery Specifications"; readers voted it unhelpful (2 of 12 on the page). The live target now redirects (301) to knowledge.netflix.net, which redirects to a login, and the help-centre API returns 404 for it. An Internet Archive memento of the target (page version 5.1, captured 2024-08-10) is readable and holds the numbers: 48 kHz, 24 or 16 bit WAVE Extensible, 5.1 required and 2.0 optional, listed 8-channel orders, mono duplicated on channels 1 and 2, -27 LKFS +/- 2 LU dialogue-gated, -2 dBFS true peak, downmix trims. It is a past version of a spec whose current text was not readable.
