Absolute Band Powers


I’m trying to compute the raw FFTs and absolute band powers generated by Muse and was looking at a past forum answer for help but I can’t get the right range of values.

The first step I’m trying to do is compute the raw_fft0 file, and while my end result looks superficially like the raw_fft0 file, my values may be too big or too small. So, some of them aren’t in the -40.0 to 20.0 range that the Muse documentation says they should be in if you follow their process. Would someone mind giving me some pointers in the right direction?
