Whether you’re making pop, hip-hop, or EDM, chances are your music is going to include sub-bass. For those who aren’t familiar, sub-bass are low-pitched notes below approximately 60 Hz, and often go below the lowest frequencies that humans can actually hear. In other words, you often can’t hear sub-bass; rather, you feel it. For example, if you’re seeing a concert and the DJ builds to a drop, then the whole room starts vibrating with low frequencies, that is sub-bass. As electronic drums and midi instruments continue to play a bigger and bigger role in popular music, the use of sub-bass is becoming standard. But since humans often can’t actually hear frequencies that low, producers have to come up with ways to bring out the pitch. So, we compiled five secrets to making your sub-bass audible.
