Rogue Amoeba has been a favorite developer of mine for quite a while. Apps like Audio Hijack and Airfoil have proved immensely useful for me over the years. Their latest release is Fission, another slick app that joins their stable of audio related tools.
Fission makes it brain-dead easy to chop and slice audio for whatever purpose. The commands are straightforward and the beauty of Fission is that it can edit MP3, AAC, Apple Lossless and AIFF with no loss of quality. In some programs, you need to convert an MP3 to a WAV or AIFF file, then edit and re-compress. Not so in Fission, which translates into excellent quality audio.
It’s ideal for situations where you want to split a long MP3 up into multiple files, as you can chop your file up at once in Fission, and then export the sections you've created into individual files. Perfect for live concerts or radio shows.
Creating ringtones from your favourite songs is also a cinch with Fission, saving you the hassles and dangers of scouring dodgy websites, or even paying a dubious source for a 10 second tone. This sort of stuff can easily done in other apps (even free apps) like Garageband or Audacity, but Fission's simplicity and lossless MP3 editing puts it in a class of it’s own.
It’s ease of use makes it a dream for any novice, or even something quick and simple for the pro who just needs to get things done. Fission is available for US$32, although a full feature demo is available. However, the quality of audio saved with the demo will be degraded with a series of audio fades.
