JUCE
JUCE is an open-source cross-platform C++ application framework for desktop and mobile applications, including VST, VST3, AU, AUv3, LV2 and AAX audio plug-ins.
The amount of high performance, production grade, massively tested libraries written in C++ is unbeatable. I will be honest here, it's easier to improve C++ security by implementing a compiler that produces safer C++ (like Typescript to Javascript) than rewriting everything in any other language (Rust, Zig, Odin, whatever).
I mean, could you estimate the cost ($ and time) it would take to rewrite the best audio framework in any other language? (https://juce.com/).

darvaza
Darvaza is a multichannel audio gate with a twist : whenever the gate closes on your input signal, you get a perversion of your source spat back at you.

> Is it guaranteed that an incorrect calling convention will always cause a compiler error?
A standard-conforming C++ compiler must not allow implicit pointer casts, so yes!
> I wasn't aware the calling convention was considered part of the pointer type.
Some well-designed C APIs define a macro for the calling convention that they add to all API functions and function pointer declarations. The user can then use the same macro when supplying their callbacks, which guarantees that the calling conventions match. (On modern platforms, the macro would be typically empty.)
Here's an example: https://github.com/Celemony/ARA_API/blob/1f68fba7a374b14df19.... As you can see, it is part of the function pointer type: https://github.com/Celemony/ARA_API/blob/1f68fba7a374b14df19...
That's also what I tend to do for my own C APIs.
> I guess I had some assumptions about calling conventions that needed to be straightened out
I also learned a few things in this discussion, so thanks for that!
