Whether it’s cleaning up existing recordings or making something new sound incredible, there’s always AU or VST plug-ins to install for your needs. Free Adobe Audition plug-ins are great for learning the skills required before investing in commercially available products.
There are also a huge number of studio-quality AU or VST audio plugins for those with more advanced skills and budgets. Whether you need a voice improved or music adjusted, Adobe Audition is the perfect way to explore them all. It doesn't matter if you use macOS or the Windows operating system, VST audio plug-ins are there to help.

Voxengo SPAN
If you want to see what your audio waves and frequencies look like in Adobe Audition, then the Voxengo SPAN VST is one of the best free audio plug-ins there is.
The SPAN is a real-time sound spectrum analyzer that provides a visual representation of your audio tracks. Once installed, SPAN displays the pitch and amplitude of your audio and lets you EQ. It can identify a note, and the band-pass filter lets you hear what part of the signal you are looking at.
Multi-channel sound analysis is supported, so you can examine multiple sources simultaneously, and there are scalable windows for more or less detail.
SPAN may be free but it's another excellent example of a VST plug-in. It outperforms many of the paid VST plug-ins rivals, and is one of the best VST audio plug-ins and well worth a download and install.

Sonimus SonEQ
The SonEQ is another example of a great, free VST plug-in. When it comes to EQing, your audio files will sound like they belong together.
SonEQ lets a producer sculpt their sound while remaining both user-friendly and straightforward. The plug-in has three band equalizers for EQ and a preamp with a bass booster for low-frequency sound that needs tweaking. The software also supports a sample rate of up to 192Khz, which should satisfy everyone, and works as well on music as it does on a voice.
Getting EQ right on your file can make a huge difference to a voice or music, and the SonEQ is one of the best VST plug-ins available for download. If free VST plug-ins can be this good, why pay?
Klanghelm DC1A Compressor
A good compressor is another important effects tool to have for your audio, and the free Klanghelm DC1A VST is a great example of a free plug-in.
It looks simple, and the clean, retro interface is extremely straightforward. But don’t be fooled by appearances — the results are amazing. Excellent filters mean you’re really able to add character to your sound. Additionally, it has a Dual Mono feature, so it can process the left and right-hand channels of your audio separately.
This is one of the easiest VST plug-ins to play around with, and while there are more complex audio plug-ins available, the Klanghelm is a great tool for learning how to work with compressors.

Techivation T-De-Esser
Too much sibilance in your host's voice? Harsh high frequencies causing problems? Then you need a de-esser, and the Techication T-De-Esser VST plug-in is a great choice.
Not everything needs to be complex to work, and that’s true of the T-De-Esser. The sibilance and high-frequency problems simply vanish to create a natural, clear vocal. The final sound also doesn’t sound overly processed, even with background noise, which can be an issue when using other methods. With mono and stereo modes available, this is a great way to rescue old, poor, or variable recordings.
If you need a simple, one-size-fits-all de-esser for your vocal that sounds better than its free price tag would suggest, this VST plug-in is the one to go for.

The original HG-2 is a vacuum-tube-driven piece of hardware that can make anything sound fantastic. Thankfully, however, there’s now a software version as a VST plug-in.
The HG-2 does everything its hardware progenitor can do and then some. The plug-in is designed to add harmonics, compression, and saturation to audio. A clutter-free control panel lets you adjust the parameters, plus the pentode and triode settings, which allow you to adjust the harmonics.

FAQ
How to Install VST Plug-ins in Adobe Audition
Most VST plug-ins come as a VST file which needs to be installed and work the same way in Audition as they do in FL Studio, Audacity, or most other DAWs.
Firstly, enable VST plug-ins, as by default they are disabled.
Launch Adobe Audition, go to the Effects menu, and choose Audio Plug-in Manager.
Click on the Add button to choose the folder your VST plug-ins are stored in when the dialogue box appears, or browse to find the file.
Once the folder has been selected, click Scan for Plug-ins.
Adobe Audition will then scan for all installed plug-ins and list them. You can either enable them all or select the ones you require.
Does Adobe Audition Come With Plug-ins?
Yes, Adobe Audition comes with a range of pre-installed audio plug-ins and effects.
However, while many of these audio plug-ins are good starting points, there are often better options that move you beyond the basics.
What is the Difference Between VST, VST3, and AU Plug-ins?
When it comes to the difference between VST vs VST3 there are a few things worth knowing alongside AU. When selecting the Effects menu in Adobe Audition, you will see that VST and VST3 options are listed.
The VST3 extension has been created as a more recent version of VST plug-ins. It’s more sophisticated and has added new features, but both work in the same way.
For Apple users, there is also the AU option. This stands for Audio Units and is just Apple’s equivalent. Note: These also work in the same way in Adobe Audition.
Glossary:
- AU: Audio Units, Apple's equivalent of VST plug-ins.
- Compressor: Used to change the disparity between the quietest and the loudest part of an audio signal to help it sound consistent.
- DAW: Digital Audio Workstation. Audio recording software such as Audition, Logic Pro, FL Studio, and GarageBand.
- De-esser: Tool designed to remove high frequencies and sibilance. This is especially prominent in certain spoken sounds, like a long “s” or “sh” which can sound harsh and unpleasant.
- EQ / EQing: EQ stands for Equalization and is a way of changing and manipulating frequencies within a recording to either bring out or reduce certain sounds. In essence, a software graphics equalizer, but more advanced.
- Mastering: Putting the finishing touches and final changes on your completed track so that it sounds as good as possible
- Mixing: Balancing different tracks against each other to make sure they all sound correct when played together. This can be podcast hosts, musical instruments, or vocals - the process is the same.
- Plug-in: Software extension for DAWs, usually in the AU, VST, or VST3 formats.
- Reverb: Echo, basically, but created by software rather than naturally.
- Spectrum Analyzer: A visual representation of an audio signal designed to show the amplitude of frequencies within that signal.
- VST: Virtual studio technology. VST plug-ins are an interface standard for software audio effects and plug-ins.
- VST3: Most recent version of VST plug-ins with expanded features.
- Wet and dry signals: A dry signal is one without any effect on it. A wet signal is one with effects on it. Some plug-ins let your blend the two together to get a better balance between the unaltered sound and the one with effects.
- Zero-Latency: Latency is the delay between applying an effect and hearing it. If there is zero-latency the effect is applied instantaneously.
