New OSS Google Lyra codec: Applications?

https://news.slashdot.org/story/21/0...andwidth-usage

According to Slashdot, this newly open sourced Google Lyra codec compresses bandwidth by using machine learning instead of dsp techniques and is capable of compressing audio considerably.

How can it be

1. Tested?I thought of firing mp3s at it through a player as input, but it's the output you'd want. It's also speech, not music. There's also plenty of single voice recordings available on some sites.
2. Played back? I had fewer ideas here.
