Fission Fission v 2.1.4 Oct 14, 2013 MacOS X Intel
Fission now offers full support for developer preview versions of Mac OS X 10.9 (Mavericks).

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.

A conflict with Many Tricks' window manager Moom, which caused the selection of split points to fail, has been handled.

Assorted rare crashes should now be even more rare, so rare that you might suspect they're gone entirely, which they are!

There are probably other improvements which we've forgotten. The best way to be sure you've got them is, of course, to update.

    Fission est l'outil idéal pour découper un long fichier audio en plusieurs morceaux, ex: l'enregistrement d'un concert, conference ou d'une repete. Ça va vite. On enleve le surplus, on fade in/out, on crée les plages, on tag les morceaux et on exporte. En 5 mn, c'est pret!
    Par contre, ce n'est pas un logiciel pour les musiciens je trouve, préférez Amadeus Pro ou autre, pour la bidouille, création de loops, effets VST/AU, fusion de piste etc.
    daniela.lucie
    J'ai acheté hier la version 1.1.1... Effectivement c'est un logiciel très intéressant pour segmenter en plusieurs morceaux un gros fichier. Le gros hic c'est qu'il est en anglais. Merci de me dire où trouver tuto ou manuel en français ?
