# AM-frequency / envelope-frequency scale title?
# bevor fit noch filtern mit 15Hz damit AM-Modulation rausgefiltert wird und nur noch envelope übrig bleibt.
# Dazu running average mit n wobei n über samplingrate und delta f bestimmt wird
# Dazu running average mit n wobei n über samplingrate von spectogram und delta f bestimmt wird
# samplingrate über overlap muss dabei aber größer sein als samplingrate die noch übrig bleibt wenn ich mit delta f frequency gefiltert hab
