Well, it looks like Skype is about to shove off. It hasn't played any kind of important roll in my life since before Microsoft bought it.
I still have the Skype 0.97 beta install I downloaded in 2003, though, for what it's worth.

Speaking of that:

Who remembers when the Skype echo test used to sound like this, before it was replaced by what I think still exists? Each supported language has it's own localized recording, but I didn't capture those.

@BorrisInABox I remember being really put out that she clearly says beep, and it's a ding.
@cachondo Oh good, it wasn't just me. To be fair, the artifacts kind of washed the ding out to the point where it was more of a wuh.
@BorrisInABox what encoder were they on? speex? Some opus thing?
@cachondo It was their own custom thing, called Silk, which eventually became part of Opus.
@BorrisInABox I knew you'd know that. Thank you.
