I’m new to Codea and still exploring its capabilities. Is it possible to build a music visualiser in Codea? One way would be if I could import the Luafft package into Codea. I assume that’s not possible. Is there any other way to analyse frequencies in Codea?
Since LuaFFT is written in Lua you should be able to just add it in a tab in your project. But there is no API for reading audio from the microphone, if that is what you need?
Here is some code for a silly visualization of notes generated in Codea.

Thank you - I’ll check that out.
I was thinking of using a .wav file to drive an animation. An alternative would possibly be to use the midi data from which the .wav file was generated.
