I’m trying to do a STFT that matches how Muse does it to make sure I understand it, and for some reason mine is coming out noisier. Here is the Muse data, as 10^absoluteGamma to remove the log scaling

And here is my attempt, adding the power values from 30 to 44 hz, 256 point window, moving by increments of 26 points - edit: and using a hamming window:

It’s similar but noisier…is there some noise reduction setting that I need to turn on or am I missing something else?
