So in the example, we went over, you will add this to your bass track. Starting with Fruity Limiter, add it to the track you want to duck out of the way.

In FL Studio, there are many ways to achieve this. Because low-end frequencies carry the most energy, these sounds will clash with each other, creating unpleasant phasing and making the low end less powerful than before. This is useful for taming two sounds that simultaneously play together and share the same frequency range. Typically, this was used to lower the volume of the bass whenever the kick drum hit.
