The performance in the examples is phenomenal. And at 3 kbps? It just blows opus and speex out of the water.

Really excited to see if it holds up when they roll it out in Duo. I remember noticing the ML based improvements in Duo kicking in when talking to my Dad a while back (US<->EU video call and he was using mobile data). Was even more impressive seeing it work in the wild.

Duo video and audio calling for me have been the best for repliability and latency comparing it vs zoom and others. The ML techniques they use to fill blanks + use of AV1 are really great.

For those unfamiliar, Duo is Google's video calling app.
