With Fission, you get lossless editing of audio files, including MP3, AAC, Apple Lossless, AIFF and WAV formats. That’s right, you can edit compressed MP3 and AAC files without any loss in quality and without worrying about going back to the master copy. This saves time.

In fact, it only offers a handful of basic features, which include copy, paste and trim audio, as well as split files. The purpose of Fission isn’t to do everything but to do a few things really well. In this, it accomplishes its goal. If you want a user-friendly losses audio editor, add Fission to your tool chest.
