Rogue Amoeba has released version of Fission, its audio editing software for Mac OS X. It’s available for US$32 at the Mac App Store or at the Rogue Amoeba web site (

Owners of older versions of Fission can upgrade for $15. For users who purchased Fission after April 1, a complimentary upgrade is being provided, with upgrade information being sent directly via email.

The most noticeable change in Fission 2 is the complete overhaul of its user interface. What’s more, it’s no longer limited to saving to a file’s original format; thanks to a new exporting engine, Fission can now export audio to a multitude of file formats. After editing a file, users can save it to MP3, AAC, Apple Lossless, FLAC, AIFF, or WAV, getting the exact audio file and format desired.

The new Batch Converter tool uses that same engine to make it possible to transcode dozens of files quicker. Speaking of FLAC, Fission now has full support for the popular lossless audio format.

Fission now has support for sharing directly to SoundCloud. SoundCloud is social sound platform, allowing anyone to create sounds and share them everywhere.
