In the example above, we need to collect 8192 samples before we can run the FFT, which when sampling at 10 kHz takes 0.82 seconds. If we tried to get smaller FFT bins by running a longer FFT it would take even longer to collect the needed samples. That may be OK, it may not be.

Jun 25, 2018 · The FFT is a display of the magnitudes of the fourier frequencies in the data. Therefore, if you zero the lowest FFT data points, you will filter out low frequency information such as a slowly rolling baseline. If you zero the highest FFT data points, you will filter out high frequency noise in your spectrum.
So to take the FFT of 10 seconds of audio, you have to record onto an SD card, then take the samples out say 256 at a time, do the FFT and then save it back into another file. The FFT needs space to work things out and you can't make the frames too big on an Arduino.
