Multiband compression is an extremely versatile mastering tool. It splits the incoming signal into separate (user selectable) frequency bands and allows you to compress each band independently.
This allows you to apply more compression to the bands that you feel need it without affecting the mix sonically.
In this screencast, I’ll cover multiband processing using Logic Pro’s stock plugin, Multipressor. We will use the plug-in to fix some areas in our track. We will enhance our low end and tighten up our high end.
