Fission audio editor released for Mac OS X

Rogue Amoeba’s ‘Fission’ is a streamlined audio editor designed to get you editing in minutes, not hours. It works with MP3, AAC, Apple Lossless and AIFF audio, enabling you to instantly trim and split files with no quality loss.

Fission uses:
• Losslessly edit MP3s, AAC, Apple Lossless and AIFF files. No re-encoding or switching formats means perfect audio quality for your files.
• Break a long recording up, by using split to create multiple files.
• Remove unwanted audio, like commercials, from audio you want to keep.
• Fade audio in and out to create a pleasing listening experience.
• Create MP3 and AAC ringtones for your cell phone.

Fission is available as a trial download and retails for US$32. If you already own Audio Hijack Pro, you can purchase Fission for $18.

  1. I’m not sure this is worth the price. I can do most everything this program does in GarageBand, and I’m pretty sure it doesn’t affect the audio quality at all.

    If this app was cheaper I would purchase it, but even for $18 (I own Audio Hijack Pro) it seems a bit expensive. The metadata editing is a nice feature though.

  2. Tommy Boy, I’m not sure when the feature first appeared, but I’m pretty sure it was there from the beginning. Currently it is very easy to edit MP3s, Apple Lossless files, etc. with GarageBand. Simply click on the media browser (the button in the bottom right of the window), and drag an audio file into the mixer. This doesn’t work for music with DRM, though.
