Tract looks neat, and I agree that making inference with rich signal support would be a killer app.

I'd love if they did this with pytorch. Tensorflow is quickly falling out of favor.

Deploying models in Rust makes a lot of sense. It's a little rough around the edges, though. (I use Rust bindings to libtorch for https://vo.codes )

Sonos has done some scummy things in the past (bricking units to prevent resale or refurbishment, deactivating old hardware, etc), but they operate in a very hard business sector against giants with monopolistic loss leaders, and this is a really cool open source release. I'm not aiming to buy more Sonos equipment, but I like them a little more now.
