Fission 2.1.4 – Streamlined audio editor.

Fission 2.1.4Fission can crop and trim audio, paste in or join files, or just rapidly split one long file into many. It’s streamlined for fast editing. Plus, it works without the quality loss caused by other editors, so you can get perfect quality audio even when editing MP3 and AAC files.

Key Features:

  • Edit MP3, AAC, Apple Lossless, and AIFF files withno quality loss
  • Quickly split a long audio file into smaller files
  • Remove unwanted content, such as commercials, from your audio file
  • Re-arrange audio in a single file, copy audio from one file to another, or merge with a quick drag and drop
  • Create great-sounding MP3 or AAC ringtones for your cell phone.

What’s New

Version 2.1.4:

  • Fission now offers full support for developer preview versions of OS X 10.9.
  • Fission is now a 64-bit application. That is literally twice as many bits as before. You probably won't notice much difference just yet, but this will enable performance gains in the future.
  • The QuickTime engine for opening file has been replaced with our own internal libav. Some extremely rare file formats may no longer be supported. Get in touch if you a format you use is missing.
  • Fission has an entirely new saving pipeline. Hopefully, you won't even notice, it will simply work. Oh, saving a ringtone from the Mac App Store version of Fission works a bit better, that's potentially noticeable.
  • Dragging a song from iTunes into the Mac App Store version of Fission should now work the first time. Previously, it only worked after two tries. Yes, really.
  • The License window has been overhauled, with HTML. Neat!
  • Chapters which contain multiple images now load images more logically (grabbing the first image in the chapter).
  • The app now has a hidden "Check for News" option, accessible by pressing option while in the Fission menu.
  • Fission's debugging window has been slimmed down.
  • Fission's now better handles excessively large AAC and Apple Lossless files which violate their respective specifications.
  • Many other small improvements have been made. They're not worth spelling out, but they're in there, and they're nice.
