Mastering is the process of applying a final polish to your mix to make it sound as good as possible on all playback systems. Once you have mixed your tracks, you can move on to mastering.

You can then adjust the parameters of the effect using the knobs and sliders in the plugin interface.

To add an effect to a track, simply click on an empty slot in the Mixer and select the effect you want to use. The Mixer allows you to adjust the volume, panning, and EQ of each track, as well as add effects such as reverb, delay, and distortion. In FL Studio, you can use the Mixer section to mix your tracks and apply effects.

Mixing and mastering are critical aspects of music production that can make or break the quality of your final product.
