Get dB(a) level from AudioKit in swift

问题

I am attempting to get dB(A) readings from audio recorded from the microphone from AudioKit. I attempt to pass the amplitude tracker into the AKFFTTap object, but it always returns an array of zeros when I call AKFFTTap.fftData. Does anyone have experience with getting dB(A) values from AudioKit and the microphone.
