unit libraries for us? …yes!Are physical unit libraries for us? ● “Physical units don’t cover our use cases” ○ Not just about “physical” quantities/units ● “Don’t handle non-linear units” ○ nholthaus …Digital audio considerations… ● Mostly operating on float ● Don’t want unnecessary conversions ● Use 3rd party APIs (float, unsigned) ● “Modulation rate” is a frequency (Hz)Musical tempo …MIDI example PCM²}What’s next?Are physical unit libraries for us? ● Do all my examples work in Xcode 15? ● Should we use Au in the meantime? ● Contribute to decibel units in mp-units ● Experiment with FFT and complex numbers

Python? ● Writing extensive APIs in Python - low boilerplate ● Familiar for domain experts ● Easy to use ○ Amazing interactive support out of the box (IPython) ○ Jupyter notebooks provide a great research time, others use python to do that Everything compiled with clang++12 -fPIC -O3Some perf numbers: per increment runtime https://news.ycombinator.com/item?id=34663930 Out in the wild case of noticing high boost::python::object ○ boost::python::object is a smart pointer around a PyObject* ○ Only useful to use bpy::object if you’re going to keep it around ○ Why would we want to do this?Arguments to functions
