It seems laggier than LASP #5

Do you know why that could be? I thought it'd be due to jobs returning FT result a frame after but DftBuffer completes on the same frame... Mystery.

If you're comparing DFT with filter banks (LASP), yes. You can ask ChatGPT why FFT (DFT) is laggier than filter banks.

chatgpt is useless, I asked claude and I sorta get it: the lag for FFT = duraction of a wave at the lowest frequency that the FFT resolves too, whereas filter banks each frequency is resolved at each wave's duration: high frequency resolved at 1/hz and low frequency at their own. Is that it?
