Audio
The /Library/Audio folder stores shared audio resources used by macOS and installed software, such as plug-ins, MIDI content, and system-wide sound data.
What is Audio?
The /Library/Audio folder is a shared macOS library location for audio-related files that are available to all users on the Mac. Apps and audio tools use it to store components such as Audio Units plug-ins, MIDI configurations, loops, impulse responses, sampled instruments, and other sound resources that need to work system-wide. Music production software, virtual instruments, recording tools, and some Apple audio features may read from this folder during normal use. Users commonly encounter it when managing disk space, troubleshooting audio plug-ins, or removing old creative software. Because it can contain active content for professional audio workflows, the folder is best treated as a shared resource directory rather than general clutter.

Safety overview
Status: Use with caution
Files in /Library/Audio can be used by macOS, Logic Pro, GarageBand, Audio Units hosts, and third-party music or recording software. Deleting plug-ins, MIDI data, loops, or instrument content from this folder can disable sounds, break plug-in loading, or cause projects to open with missing audio resources. Review subfolders carefully and remove only items you can tie to software you no longer use.
Recommendation: Keep /Library/Audio unless you are cleaning up specific audio content from apps or plug-ins you have already uninstalled. If you need to free space, inspect the folder by subfolder or vendor name and remove only clearly unused components so your music apps and existing projects continue to work correctly.
