The current FFT I see is completely different from the one I used then so I think that node has been replaced? How would I do that in gamma? All the tutorials and the FAQ stuff is old.
Assuming that you’ve installed the VL.Audio nuget and one of the necessary ASIO drivers, the FFT node actually works pretty much the same as the one you know from beta. Check out the “HowTo Use FFT” help patch as an example.
