Interesting. How does it compare to e.g. Faust or the SuperCollider language? What's the "unique selling point" of Audion compared to other "music programming languages"?
The integration with supercollider (SC) makes SC syntax somewhat simpler? That part may be somewhat opinionated however Audion does not need SC, if you have hardware or software instruments you can use that.
So I think in one phrase: A small language that is fun to write and lets you hack music.
