Fair enough, most of the critical code in this case is written in Rust. A Rust transcription library popped out of the project `transcription-rs`. And there is a real-time audio library I'd like to put out which allows for filters. I could have called out to ffmpeg or similar, but I chose to implement an audio pipeline myself (for better or worse)

So makes sense, but there are benefits to writing a desktop application backend in Rust for the ecosystem as well.
