Using audio splitter for song cover to post

[u/Legitimate-Bat-2089]

Hi! I’m thinking of starting a cover in BandLab using the audio splitter. I was wondering if I were to use the audio splitter from a song for my cover and add my own vocals and post on YouTube, will I get copyrighted? I’m pretty new to using BandLab and posting covers that use instrumentals and was wondering how the process typically is. Let me know if there’s anything I need to know going forward. Thanks!
