Choose the format your DAW officially supports on your operating system. VST3 is broadly cross-platform, AU is Apple’s plugin architecture, AAX is the Pro Tools format, and CLAP is an open plugin interface with growing host support.
The compatibility map
A plugin format is the interface between a host and a plugin. Buying a license does not guarantee that every included format works in every DAW. Check the developer’s current compatibility page for the exact operating system, processor architecture, host version, and plugin build.
| Format | Typical environment | Check before installing |
|---|---|---|
| VST3 | Many Windows, macOS, and Linux hosts | The DAW’s current VST3 support and scan path |
| AU / AUv3 | Apple platforms and compatible hosts | macOS or iOS support, host sandbox rules |
| AAX | Pro Tools and related Avid environments | Native/AudioSuite support and current Pro Tools compatibility |
| CLAP | Hosts and plugins that implement the open standard | Exact host and extension support |
Do formats sound different?
Equivalent builds are intended to expose the same processing, but they can differ in host integration, MIDI behavior, automation, sidechain routing, preset locations, sandboxing, and update timing. If two formats null differently, confirm oversampling, quality mode, random modulation, latency compensation, and saved state before blaming the interface itself.
For a stable session, pick one supported format per plugin and keep installers archived. Changing format mid-project can break automation or recall even when the visible product name is the same.
