hello guys! that’s my first post here so i’ll try to make it brief. Does anyone know why is this keep happening? I edit a part of my recording, i save it and the next day when i open it again the audacity has changed the volume as you see in the screenshot below. I fix it, (make it all even again) but the next day it does it again. Does anyone know how i can fix it permanently? (keep in mind that i’m new to this and that i’m not a musician or an editor of any kind, i’m just trying to make a podcast) Thank you in advance.
Possibly you have realtime effect engaged …
update!
i just noticed it happens when i copy paste a piece of my recording, if that helps 
Those look like envelopes. Try disabling envelopes and see how that goes.
