Fission: Fast & Lossless Audio Editing
Fission is an audio editor designed with simplicity in mind. Using Fission, you can quickly and easily trim and split MP3, AAC, Apple Lossless, FLAC, AIFF, and WAV files, with no quality loss. Split one large audio file into multiple files. Remove sections of audio from a file. Fade audio in and out. Fission will help you accomplish your editing needs with ease.
You can also use Fission to export audio from one format to another (save AIFF files as MP3, or Apple Lossless as AAC), to batch convert a group of files between formats, and even to create iPhone ringtones.
Editing audio has never been this simple or this inexpensive. Fission makes simple audio editing fast and affordable!

New and Updated In Fission 2.1.3
The name of the game is bug fixes. Version 2.1.3 removes almost two dozen incidences of stupidity, dumbness, and boneheadedness.
The Batch Converter has been updated to properly handle all Windows Media files, as well as ALAC-encoded CAF files, and more.
Several additional VoiceOver improvements have been made, with labels on previously unlabeled controls. We're always working to improve this.
Clip tabs now always show the clip name.
There's much more - it's all minor, but it's all very nice to have fixed as well.
