Search for the compilation flag "CHROME_WIDE_ECHO_CANCELLATION" in the Chromium sources, and you will find your answer. Can't tell you anything else due to NDA

  It's kind of nuts that (I'm assuming) the source code is publicly available but the developers who wrote it can't talk about it. (I realize this situation isn't up to you and I appreciate that you chimed in as you could!)

    This is super common. When I worked at Mozilla, most stuff was open, but I still couldn't talk about stuff publicly because I wasn't a spokesperson for Mozilla. Same at OpenDNS/Cisco, or at Fastly, and now at Amazon. Lots of stuff I can talk about, but I generally avoid threads and comments about Amazon, or if I do, it's strictly to reference public documentation, public releases, or that sort of thing. It's easier to simply not participate, link a document, or say no comment than it is to cross reference what I might say against what's public, and what's not.

  Thanks, I see it's a user toggle too chrome://flags#chrome-wide-echo-cancellation or edge://flags/#edge-wide-echo-cancellation . All these years I was praising my macbook, thinking it was the hardware doing the cancellation, but it was Chromium the whole time.
