So most of us know how to sidechain a kick to a bass to get that classic dance pumping sound, but what about using the kick to duck the bass by a specified frequency? Or, reversing the actual frequency the kick takes up onto your bass, instead of just volume? For example, instead of lowering the bass volume overall when you feed a kick signal through a compressor, the kick frequencies can actually invert those same frequencies on your bass sound, or you can specify a frequency range to reduce. This technique, is called frequency ducking. I'll be using a kick and bass that are intentionally uncomplimentary.
Step 1: Listen to the un-effected original
Here's a sample of how they sound together without frequency ducking. Put your headphones on, or listen on your studio monitors. This lesson I'd consider 'deep listening,'
