Change FFT Window Size?


#1

Hi there,
I’m wondering if it’s at all possible to change the 256 sample Hamming window size to something else. I’m interested in looking at fluctuations at shorter timescales, and am willing to sacrifice some frequency resolution. Of course, I could get the raw data and run the FFTs myself - but it’d be easier if I could just change the window size! :stuck_out_tongue:
Thanks much,
Ryan

Dear Ryan

It’s a good question, and I’m interesting in it too.

I had try FFT in raw EEG, but the results are different from the FFT made by Muse… I don’t know why… May be we can discuss it.

Thanks Much
