The reverse crash cymbal technique is one of the most common impact accentuators. Some producers prefer imitating this sound with automated white noise samples fading in, or a reversed tambourine sample instead of a reversed crash cymbal. Either way, that whooshing sound leading up to the chorus can be so easily overlooked, but it’s one of those sound effects you’d miss if it wasn’t there.
At this point, your vocal should be sounding pretty good. There should be no noticeable frequency problems, leaving you with a very natural-sounding performance. Next, you’ll want to focus on adding color and character to your vocal using additive EQ.
