What is Fission?
Fission is a native Mac audio editor designed for quick, precise work on common audio files. It helps users trim recordings, split long files into separate tracks, join clips together, and make small edits without the complexity of a full digital audio workstation.

Safety overview
Status: Safe
Fission is legitimate Mac audio-editing software. Access to audio files you open is normal for its purpose, and removing it mainly affects your ability to edit or export projects with this app. As with any editor, keep copies of important source recordings before making major changes so you can return to the original if needed.
Recommendation: Keep Fission if you use it to edit recordings, music files, podcasts, or other audio on your Mac. If you no longer need it, you can remove the app, but save any important source files and exported work you want to keep first.
