I hear you on that. It is especially embarrassing that despite the callbacks being essentially the same since the '90s, there are still ~5 APIs to do the same thing, and all of them are this ugly. I wonder how LADSPA and LV2 look... LV2 at least has units, so you don't need to use some arbitrary rule to convert your Hz, dB, octave, and other units to a 1.0f > float > 0.0f and then that float maybe into an integer. Putting aside plugin/processor APIs for a moment, I think platform APIs are even worse. I mean, PortAudio, whose namesake is portable audio, does not include a functioning PulseAudio sink, and doesn't function correctly on most GNU/Linux systems of the last decade.
