Here's some advice..
If you really want to make some 17bucks inspired vocals, you gotta first say things, something like: "If you wanna go inside there i'll recomend not doing it" yk yk. And then cut some part of that audio and add some reverb or that stuff and it will sound very cool. You gotta first test the vocals, and then compare it with some 17b song if it sounds great.
I hope you find this very helpfull.
to do this and make actual fnf songs with vocals like these..
1: search up your favorite fnf character vocal meter (example) (bf vocal meter)
2:record the video of it and download BandLab (make sure it has different tunes of the characters going up to make sure that’s the real video)
3: import it to the BandLab editor and open up the pad and import the sounds. (Optional: you can make your own vocals)
4: make sure you have your vocals cut out and then boom make your song with your vocals!
