Have to think about how to deliver this data for you, but essentially it will be an FFT that shows what the prominent frequencies are at play and how they correspond to well-understood "alpha", "beta", "gamma", etc. waves.

Does this come out of the device, or this something we post process?

jbrukh commented 11 years ago

Out of the device.

Only if you explain to me exactly how FFTs work. Herp herp.

Sorry, I misunderstood your question. We need to post process the data and in it through an FFT C lib. I already did this for the NeuroSky device, have the code.

Does this need to be done real time?

jbrukh commented 11 years ago

No, just as a post processing thing. It's a nice to have to begin getting some semblance of what's actually in the data.
