# zu eigenmannia: jeden fisch mit amplituden von max und min von modulationstiefe und evtl 1 oder 2 dazwischen
# und dann für die am frequenzen von apteronotus für 15Hz delta f messen
# mit zu hohem RMS rauskicken: gain/rms < ... (?)
# gain kurven als array abspeichern
# daten von natalie zu eigenmannia mit + / - delta f anschauen ob unterschiede
# unterschiedliche nffts auf anderem rechner laufen lassen evtl um unterschiede zu sehen?
# einfach passendes n verwenden um AM-beats rauszufiltern? ...Menge Datenpunkte zu gering
# long term: extra datei mit script drin um fertige daten darzustellen, den code hier als datenverarbeitung allein verwenden
# darstellung: specgram --> rausgezogene jarspur darüber --> filterung --> fit und daten zusammen dargestellt, das ganze für verschiedene frequenzen
# liste mit eigenschaften der fische (dominanz/größe) und messvariablen (temp/conductivity) machen um diese plotten zu können
