Google Announces Lyra V2 Low Bit-Rate Voice Codec
Lyra V2 is summed up by Google as being "a better, faster, and more versatile speech codec...a new architecture that enjoys a wider platform support, provides scalable bitrate capabilities, has better performance, and generates higher quality audio."
Lyra V2 makes use of the SoundStream end-to-end neural audio codec, continues showing much better performance than the Opus audio codec, improved audio quality, and more. The Lyra V2 open-source code is available today.
More details on Lyra V2 can be found via the Google Open-Source Blog and the code is available on GitHub. The GitHub release notes mention Lyra V2 can be ~5x faster on Android devices, codec latency reductions from 100 to 20 ms, and now there is Mac and Windows support to complementing the Linux and Android support.
