All too often we see products released with relatively basic feature sets, after which they evolve into powerful applications used by professionals. That leaves few choices for those who want a simple, focused program. Think about how that’s happened with page layout, graphics, and Web authoring tools, as well as audio editing applications. That’s why it’s great to see programs like Rogue Amoeba’s Fission, which is a simple audio-manipulation program that handles numerous audio formats and provides lossless editing of MP3 and – uniquely on the Mac – unprotected AAC files. Unlike high-end audio programs, Fission doesn’t attempt to do everything; it focuses on helping you trim, split, and manipulate audio files for cleaning up podcasts, making ringtones, eliminating commercials from recorded radio shows, and more (for additional details, see “Fission Manipulates Audio Tracks of All Stripes,” 2006-09-25). Also unlike high end audio programs, Fission doesn’t come with a high price tag.
