alt Hacker NewsDo you know if there has been any progress on conical-bore brass? From what I recall (I did some graduate work in instrument modeling in the late 2000s) reed instruments could be modeled convincingly, but the feedback oscillator with the lip buzzing was very difficult to model.
There's eg https://summit.sfu.ca/item/11130 from a Tamara Smyth and Frederick Scott; Google scholar shows some citations but not necessarily conical brass in particular. That link is about trombones, so also not conical. (I read that and tried to implement some stuff in it, see https://nuchi.github.io/trombone/ for a browser-based playable version.)
Conical and cylindrical bores definitely differ but I don't see why they'd be different specifically with respect to the lip interaction, can you say more about that part?
