compute cutoff frequency
The pictures are of my FFT. I use it to extract the -3dB frequency. Also use it for the -3db to -6dB rolloff slope, not sure if this of much use yet.
I'm wondering what other ways you guys out there use the FFT. What other information can you glean from the amplitude, magnitude and even phase data?
