Re: Exact(approximate) frequency of particular brainwave state

There is a simple python script using FFT and generating graph even listening for Muse headband

I could feed it with MindMonitor CSV data.

Re: OSC streaming - data transfer not happening

I guess you are on same Wifi :-)
I made it running on MuseLab. Check your MBP Console logs. It should report incoming packets.
Sometime I need to reenable streaming if stuck.

Re: Exact(approximate) frequency of particular brainwave state

Correct, Excel FFT is limited to 4096 samples

I may not need to analyze entire 8 hours, up to 1 hour long deep stage would be enough but 4096 is anyway too little.

Did someone try in Excel ? https://www.statisticshowto.com/fourier-analysis-definition-excel/ https://www.analog.com/en/design-notes/crunching-ffts-with-microsoft-excel.html https://courses.physics.illinois.edu/phys401/sp2012/Files/Freq%20Analysis/The_Excel_FFT_Function_v...

Exact(approximate) frequency of particular brainwave state

Hello, Is there a way to know exact frequency of specific brainwave state ? Let's say I would like to know what exact frequency I've spent in Delta state or maybe most of time. Now I can distinguish only between 5 states, Delta, Theta, Alpha, Beta and Gamma. I am thinking to know more about my perso...
