When working with audio plugins, you’ll encounter different formats that are compatible with specific DAWs and operating systems. Here's a quick guide to help you understand the key plugin formats: VST, AU, AAX, Standalone, Sample Packs, and Kontakt Instruments.
VST (Virtual Studio Technology)

AU (Audio Units)

Standalone Plugins
Compatible with: Windows and macOS
Description:
- Standalone versions don’t require a DAW to run.
- These plugins function as independent applications, often useful for live performance or quick access to an instrument/effect without needing a full project setup.
Use Cases:
- Great for live performances, sound design, or practice sessions where using a DAW isn’t necessary.
Sample Packs
Compatible with: All DAWs
Description:
- Sample packs are collections of audio files (loops, one-shots, etc.) that can be imported into your DAW.
- Common formats include WAV, AIFF, and MP3.
Use Cases:
- Perfect for beat-making, sound design, and adding pre-recorded elements to your tracks.
Kontakt Instruments
Developed by: Native Instruments
Compatible with: Windows and macOS
Description:
- Kontakt instruments are sample-based instruments that run within the Kontakt sampler plugin.
- Requires the full version of Kontakt or the free Kontakt Player to use.
Use Cases:
- Ideal for orchestral libraries, drum kits, and complex sampled instruments.
How to Choose the Right Format
- Check your DAW’s compatibility:
For example, Logic Pro users need AU plugins, while Pro Tools users need AAX.
Consider your operating system:
If you’re on macOS, both AU and VST are often options. On Windows, VST is the standard.
Look for standalone versions:
If you want to use a plugin outside of a DAW, see if a standalone version is available.
Explore sample packs and Kontakt instruments:
- If you’re working with samples or complex virtual instruments, these formats can expand your creative possibilities.
