As it happens I am the author of the audio-buffer and constraint-algorithm implementations in webrtc-rs/media: https://github.com/webrtc-rs/media/commits?author=regexident

So even though we are not using webrtc-rs in Daily today, we are (or at least I am) contributing to it, in hopes of it becoming a feasible option at some point.
