Mind Monitor

Hi,
I'm on a simple experiment using this app, and I got several questions while analyzing data.

(1) What is the Y axis of the CSV recorded graph?
(2) Is it possible to know the exact data of frequency(Hz) change of each brain wave using the app?
(3) I also want to know what the number such as 'Delta 88dB' in the absolute graph means.

Thank you for developing an amazing app!

#1 - The Y axis depends on which chart you're talking about, but assuming you're talking about the default one showing brainwaves, then the answer would be Power Spectral Density (bels/dB).
#2 - The frequency of brainwaves does not change, it's the power level of the range that changes. See the help: https://mind-monitor.com/Technical_Manu ... h_absolute for the ranges.
#3 - That means the Power Spectral Density of your Delta waves is 88 decibels. .. but that also is highly unlikely unless you are in deep sleep, so it probably means you have poor sensor contact, sorry!
