    FFT for super low sample rate data

    Hello. Does UE4 provide a way to do fourier analysis when the sample rate is 256 sps? (this is EEG data not audio hence the low sample rate).

    Thanks.

    I mean, you can lie, pretend it's audio at 48 kHz, and then divide all the frequency bin frequencies by (48000/256) ...

    Or, if you're OK building a C++ project, you could use a high quality free FFT library like djbfft and wrap it in a blueprint library pretty easily. (I prefer djbfft over fftw because fftw licensing is onerous.)
