I am attemping to create an FFT function that allows me to set the frequency range of the FFT, the number of bins, and windowing type. For the frequnecy range, my logic is to use a low-pass filter. If I add a filter, does it make sense to have windowing? How am I able to set a distinct number of bins in the FFT, it seems that automaticcaly the number of bins is incredibly high (I am collecting data at 48 kHz for about 90 seconds). I would like the bin width to be around 1 Hz instead of ~.01 which it currently is. How can I change this? We have another program that is able to achieve this, so I know that it is possible, but is this program cutting out data to achieve this?I am attemping to create an FFT function that allows me to set the frequency range of the FFT, the number of bins, and windowing type.
