IMPROVE TIMELINE RULER UNIT OPTIONS

I've been trying to sync an animated drummer with prerecorded drums but I can't line up my triggers with the sound waves even 60 fps making the animated drummer completely out of sync with the music. there has to be a way to slide items on a timeline without snapping directly to the beginning or end of a frame. I understand that 60fps is fast enough for visual satisfaction but in an animation project heavily based on music i would love for the animation and musical actions to occur simultaneously.
