Can anyone explain how the baking of FFT analysis works in the new Audio Engine?
So far I’ve got the realtime FFT working. ‘Start Analyzing Output’ of a submix and then using ‘Get Magnitude for Frequencies’ from that submix as pictured in the attached image.
But I can’t use the “Get Cooked FFTData” to return true. What node or process is used to cook the FFTData?
I’ve tried digging and can’t seem to find anything. Even tried turning of ‘Context Sensitive’ for ‘All Possible Actions’

I figured it out. There’s a checkbox in the actual Sound Wave uasset for generating baked FFTData.
