Fission 2: Audio Editing, Better Than Ever

Since 2006, our application Fission has been one of the most popular ways to edit audio on the Mac, with none of the quality loss caused by typical audio editors. It’s been great for quick edits of recordings from both Audio Hijack Pro and Piezo, as well as creating iPhone ringtones, editing iTunes Music Store files, and more. At six years old, however, Fission was ready for a big update. Back in April, we first previewed the next generation of Fission to members of our mailing list.

Now, half a year after first previewing it, we’re finally ready to unveil the newest version of Fission to the world.

What’s New

Fission IconIf you’ve used Fission before, you’ll immediately see that the most obvious change is its appearance. Fission now offers both a dark and a light theme, as seen above, both of which have been overhauled with fantastic new art. It’s not just a re-skin, however, as we’ve worked hard on the user experience as well. Every aspect of Fission has been examined and considered, with enhancements made across the board. The editing workflow is a snap to learn for new users, while existing users of Fission will be instantly familiar with version 2.

We’ve also packed in several major new features to make editing audio easier than ever. First up, that includes support for exporting directly to all major audio formats. You can still save losslessly to your file’s original format, of course, but now you can export your audio to MP3, AAC, Apple Lossless, FLAC, AIFF, or WAV too.

Batch Converter IconIf you want to convert multiple files, Fission has you covered there too, with the new Batch Converter. Drop an album’s worth of FLAC files on the Batch Converter, and you can have a folder full of MP3s with just 2 clicks. Converting from one format to another format couldn’t be simpler.

FLAC IconSpeaking of FLAC, Fission now has full support for the popular lossless audio format. FLAC files can be opened, edited, and saved, making it possible to change them as needed, or just export them to a smaller format for portability. Fission 2 now also supports WAV audio files, in addition to its “original four” formats of MP3, AAC, Apple Lossless, and AIFF.

Improvements to saving aren’t limited to just file formats either, as Fission now has support for publishing to SoundCloud. SoundCloud is the world’s leading social sound platform, allowing anyone to create sounds and share them everywhere. With SoundCloud support in Fission, it’s now easier than ever to get audio onto the web and to share it with others.

On top of all that, we tossed in the ability to open multiple audio files at once for easy joining or multitasking, fast creation of Chapterized AAC files for enhanced podcasts, improved iPhone ringtone saving, and more. We’re incredibly proud of Fission 2, and we think you’re going to love it. If you need to edit audio on your Mac, you just can’t go wrong using Fission.

1. Looking for our other apps in the Mac App Store? Unfortunately, Apple’s many restrictions preclude most of our applications from appearing there. As mentioned in this Knowledge Base article, we’ll always sell our software directly, even when it also appears in the Mac App Store. 

2. Unfortunately, as you may be aware, Apple provides no way for us to move existing users into the Mac App Store. If you own a Fission 1 license, we’re only able to provide a discounted upgrade through direct purchase.

You are of course able to buy Fission 2 directly through the App Store, but we have no way to provide the appropriate discount there. As such, we recommend all upgraders purchase Fission directly through our store
