Now, before we jump into the list of plugins, I think there’s two things that you might want to think about, since this is where some mixing engineers tend to screw things up and it’s something that you should avoid!
Consider Hiring a Mastering Professional
Before you delve into the wonderful world of mastering you should consider one thing…..don’t! Mastering engineers exist for a reason and it isn’t because of lazy mixing engineers.
It’s a craft that takes years to perfect and for beginners who think they can learn mixing and mastering simultaneously, I suggest learning to crawl before you can run.
There is also an important detachment from your project that a mastering engineer offers. Let’s say you have spent months recording and mixing some local dudes’ debut of the decade. Through your all your sweat and labor, you have grown attached to the music, it’s become your baby and now you won’t do anything but coddle it!
This is where a mastering engineer comes in with a fresh and professional pair of ears and hears exactly how unbalanced your prized possession really is.
That is why, if you’re a musician, for example, it’s generally recommended to have separate mixing and mastering engineers working on your album, since they will be way more objective than you.
But the same concept applies if you’re the one mixing the album… A fresh set of ears never hurts!
Consider your Stock Plugins
let’s be honest, you’re probably going to experiment with mastering your own tracks; you’re an engineer, it’s in your nature!
When you do please begin with your stock DAW plug-ins, don’t rush to spend a fortune on the top-of-the-line mastering suites. A compressor, limiter, and an EQ are the essentials you need to dip your toes in.
You will not be able to download Bob Ludwig’s talent, mastering is an artform, not a plug-in effect, and you can achieve astounding results with what comes stock with your DAW.
Now, with that out of the way, let’s get into the list!
Best Mastering Suite Plugins
Mastering suites are essentially plugin bundles that come with everything you could ever need for mastering, be it as separate plugins or all in one.

I hope this information was useful!
Have a wonderful day!
