Fission 1.0

With Fission's streamlined audio editing, you can quickly copy, paste and trim audio, as well as split files.

Fission also works with compressed MP3 and AAC formats to edit without the quality loss caused by other editors. Get perfect quality audio when editing natively in the MP3, AAC, Apple Lossless, AIFF and WAV formats.
You can create iPhone Ringtones: turn any audio file into a ringtone, with built-in iPhone ringtone saving. Insert periods of silence into a file while editing.
