Spectrogram weird line in 56hz

Post by WamBam »

From day one with the muse s and with the mind Monitor app, the spectrogram had a thin solid red line at 56hz. Spontaneous recording.. Magnitude is set between 1 and 3. Changing the Magnitude doesn't changed this line. Im definitely not concentrated in gamma. Any advice?

It's probably powerline noise from the electrics in your house. Home electricity is 50Hz or 60Hz depending where you are in the world. Try moving away from the light fixtures and other high power electrics.
