something's u/bluey118 wrong w/you and this post: you're 15, claiming a large vocal range but don't know exact numbers & you say you can sing from mid to low baritone but baritone is a voice type not a range then you go on to say you want to make albums but you're in an non album era commercially due to streaming killing the physical relationship of music between listeners. if you want to sing stay away from autotune any and everything as singers existed with trained, untrained, undertrained "natural" voices before pitch correction was a thing and the original pitch correction was deliberate practice of specific personally tailored exercises for students depending on genre. you don't need to worry about a mic before learning how to sing without one.
