“Lyra V2 is based on an end-to-end neural audio codec called SoundStream.”
Lyra V2 matches Opus quality at 50 to 60 percent of the bandwidth, and latency dropped from 100 ms to 20. It encodes a frame on a Pixel 6 Pro 35 times faster than real time. Google open sourced it under Apache. A good codec still needs Google to keep shipping it, and Google just killed Stadia.
