I heard what sounds like whispering coming from my bathtub

Please help me out people. I was going to take a leak and heard these creepy whispers coming from my tub. I'm not religious at all and skeptical of the supernatural, hence why I'm coming here first. After the 16 second mark it really does sound like it's saying "piss" I believe there's 3 possibilities, and I'll rank them from most to least probable. Most likely it's a drainage problem, or something plumbing related. Second would be someone installed a speaker in my bathroom somewhere to mess with me. This one's very worrying, as I live with just my little sister and mom. I know it wasn't either, because when I showed them the recoding they were both scared, nor would they ever do something like that. Lastly if it's neither idk what else to believe but somehow demons 💀 I really want to be logical here, so if anyone has an answer to this noises let me know. Make sure to listen to the clip with your volume all the way up. And before anyone asks I'm 99% sure it wasn't coming from outside the window. Sounded like roaring at the start, and no cars would be audible from here
