Quick public service announcement:
DO NOT BUY ALL THE PLUGINS I USE.
Use the following section as a guide to discover new mixing techniques and open your mind to creative ways to process sounds.
I'll try to list as much free plugin as I can, but I also need to be honest with you and show you exactly what I use. You can find the full list of free plugins in the resource section at the end of the course.
If you had to buy 3 plugins to fully enjoy this course, I would get:
xFer - Serum ($189 or $9 per month on Splice).
It comes with Serum FX which has amazing filters.
Waves - Renaissance Bass ($79)
Great way to generate low end to recordings that don't have any.
Waves - TransX Multi ($99)
Multiband transient designer. The secret to add punch.
These 3 plugins combined with free and stock plugins is more than enough to create professional trailer sound design.
Most stock plugins are wonderful. Don't underestimate them. Everything I list with "Ableton" in front means stock plugin, so you probably have something similar in your DAW.
If ever you see a plugin I use and you don't have it, you can probably find a 30 day demo. Not all plugins work for everyone, so you might not end up using it by the end of the trial period.
Lastly, I want to emphasize "vision over quality". The choice you make are much more audible than the quality of the plugin you use.
All that said, hope you'll find this little guide useful. Most of the techniques I write will later be showcased in the sound design videos.
