The interesting part is deployment. Deploying Julia is still in flux, and especially tricky for realtime audio. I wanna do a proper write up one day, with slides and GitHub code. Perhaps as a JuliaCon talk or local meetup.

I find that DSP tends to look like procedural C code in any language. It should be straightforward to port your C++/Rust directly to Julia, and the ergonomics are much improved (especially around AutoDiff!). See https://www.youtube.com/watch?v=SvnDr9nnOZs

Here's my older talk on audio processing with Julia. The code still works, if you change the deprecated functionality for the new equivalents covered in the docs: https://www.youtube.com/watch?v=3DfVowNFI2c
