Re: 24/96 Audacity

Ok, now i am confused about some things. I understand the Nyquist theorem saying that the sampling frequency must be twice the bandwidth of the source, but I am confused by this spectrum. What are these higher frequencies in this FFT of a 24-bit, 96kHz source? Are these really acoustic frequencies being picked up by the mics, or are they just higher harmonics or something? I am confused. I didn't think that mics could pick up frequencies this high. What is the sharp cut-off at about 24kHz? Also, if I lower the FFT size, the higher frequencies all but dissappear. Help! I am so confused.....
