Title: Google Lyra goes to open source (C++)
Post by: urak on 2021-04-07 16:26:44
Hi to all.

- Lyra - enabling voice calls for the next billion users (https://opensource.googleblog.com/2021/04/lyra-enabling-voice-calls-for-next-billion-users.html)
- GitHub (https://github.com/google/lyra)

------------------
The Open Source Release
The Lyra code is written in C++ for speed, efficiency, and interoperability, using the Bazel build framework with Abseil and the GoogleTest framework for thorough unit testing. The core API provides an interface for encoding and decoding at the file and packet levels. The complete signal processing toolchain is also provided, which includes various filters and transforms. Our example app integrates with the Android NDK to show how to integrate the native Lyra code into a Java-based android app. We also provide the weights and vector quantizers that are necessary to run Lyra.

We are releasing Lyra as a beta version today because we wanted to enable developers and get feedback as soon as possible. As a result, we expect the API and bitstream to change as it is developed. All of the code for running Lyra is open sourced under the Apache license, except for a math kernel, for which a shared library is provided until we can implement a fully open solution over more platforms. We look forward to seeing what people do with Lyra now that it is open sourced. Check out the code and demo on GitHub, let us know what you think, and how you plan to use it!

It would need a file container to be usable outside of app-app
