Understanding AAX and VST Differences

ByMunyaradzi Mafaro

AAX and VST are two types of audio plugins used in music-making software. Plugins are like apps or add-ons for the main software. They can be instruments, effects, or tools that help create or change the music.

AAX stands for “Avid Audio eXtension.” It is the plugin format made by Avid, the company behind Pro Tools. Pro Tools is a very popular software for making music, especially for recording bands and preparing songs for release.

VST stands for “Virtual Studio Technology.” It is a plugin format created by Steinberg, the company behind Cubase and Nuendo. VST is an open format, meaning anyone can create VST plugins, not just Steinberg. Because of this, there are many more VST plugins out there than AAX.

Both AAX and VST plugins come in two kinds:

Instruments

These act like real musical instruments or electronic instruments like synths. Instead of physical keys, strings, or pads, you play them with a MIDI keyboard or by drawing notes in the software. Examples are piano, drum, and synth plugins.

Effects

These change how an audio track or instrument sounds. They are used to make things sound better, more interesting, or to better fit the style of music. Examples are reverb, EQ, compression, and distortion.

Differences between AAX and VST

AAX and VST have key differences that can matter depending on how you make music.

Software compatibility

The biggest difference is which software they work with:

  • AAX plugins only work in Pro Tools. They do not work with other music-making software like Logic, Cubase, Ableton, FL Studio, etc.
  • VST plugins work in almost all music-making software except Pro Tools. They are more universal.

So, if you use Pro Tools, AAX is your only choice for plugins. But if you use other software, you will probably use VST instead.

Performance and stability

AAX plugins are made to work very smoothly in Pro Tools. They use the computer’s power efficiently and usually work without crashing. Avid tests AAX plugins extensively before letting developers sell them, which means there is good quality control.

VST plugins are more hit or miss. Some are of great quality and very stable. However, because anyone can make VST plugins, some are not as well-made or can cause the software to crash more. You have to rely on user reviews and your testing.

Variety and cost

Because VST is open and has been around longer, there are way more VST plugins than AAX. You have a bigger variety in almost any category, from pianos to compressors.

There are also many more free and low-cost VST plugins than AAX. With AAX, most plugins are made by big companies and are pricier.

VST allows small developers and hobbyists to make plugins. Some give them away for free or for cheap.

Which one is better?

So, is AAX or VST better overall? It depends on your specific needs and setup.

You may prefer AAX if:

  • You use Pro Tools. AAX is the only plugin option for Pro Tools, so you have no choice! Luckily, almost all major plugin companies make AAX versions of their products just for Pro Tools users.
  • You prize stability and performance. AAX plugins are well-optimized for Pro Tools and undergo strict quality checks. As a result, you’ll likely have fewer issues with crashing and slowdowns.
  • You don’t mind a smaller selection and higher prices. What AAX loses in variety tends to make up for in professional polish. If you just need the best and can afford it, the limited AAX options may be enough.

You may prefer VST if:

  • You use any music software besides Pro Tools. Logic, Cubase, Ableton, FL Studio, Reaper, and others are VST-compatible only.
  • You like having a huge variety to choose from. With the enormous VST plugin ecosystem, you can find multiple high-quality options for almost anything you want to do, with varying features and interfaces.
  • You’re on a budget. Many excellent VSTs are very affordable or even free. You can assemble a full plugin toolkit more cheaply by going the VST route.
  • You like supporting small developers and trying cutting-edge plugins. Small shops and even solo developers can create VST plugins, and some very creative ones push the boundaries of what plugins can do.

The bottom line

AAX and VST are simply two ways plugins can talk to music-making software. One isn’t inherently better than the other. What matters is that you can find plugins that meet your needs and fit your setup.

If you’re a committed Pro Tools user, AAX is your only practical choice for using plugins. But you can rest assured that professional developers will keep putting out great AAX plugins to keep your mixes sound top-notch.

VST opens up a whole world of mix-and-match options if you use other popular music programs. With smart searching and testing, you can build a unique toolkit drawing from big developers and tiny indie shops.

Whichever route you choose, both formats will continue to evolve, giving music makers more and better tools to realize their vision. The best plugin for you is simply the one that helps bring your ideas to life.
