Audacity
Audacity is a free, open-source audio editor and recorder for macOS that helps you record, edit, clean up, and export sound projects.
What is Audacity?
Audacity is a desktop audio editor and recorder for people who want to capture, edit, and improve sound on macOS. It is widely used for podcasts, voice recordings, music practice, basic multitrack production, audio cleanup, and format conversion. The app supports recording and arranging multiple tracks, trimming and moving clips, and applying effects such as noise reduction, compression, pitch changes, and speed changes. It also supports batch processing with Macros and can work with additional plugins and optional libraries for expanded format support. Audacity is published by the Audacity project and is also available on Windows and Linux, making it a common choice for users who want a capable audio tool without a complex studio workflow.

Safety overview
Status: Mostly safe
Audacity is a well-known audio editor, and microphone access on macOS is consistent with its recording features. Review any optional plugins or extra format libraries before installing them, because third-party additions can change the app's capabilities and trust profile. If you do not record audio, you can deny microphone access and still use Audacity for many editing tasks.
Recommendation: Keep Audacity if you record, edit, convert, or clean up audio files. If you no longer use it, removing the app is usually low impact apart from losing its saved settings, plugins, and project-related convenience files until you reinstall it.
