One crucial yet often overlooked aspect of mastering is how limiting affects the energy of your low-end. In an insightful video from The Cosmic Academy, the impact of different limiter settings on sub-frequencies is explored in depth, using top-tier plugins like iZotope’s Ozone Mastering Limiter and FabFilter’s Pro-L 2.

The video demonstrates how to use the delta function to isolate and hear only what is being limited. Taking it a step further, Cosmic Academy suggests filtering out everything above 100Hz while in delta mode, allowing you to focus solely on the low-end frequencies. This approach makes it easy to identify a limiter setting that minimally affects your sub frequencies, preserving their power and clarity.

While this technique requires a high-end limiting plugin with advanced settings, the video breaks it down in a way that is easy to grasp. If you’re looking to maintain the integrity of your low-end while mastering, this is a must-try method.
