Rogue Amoeba has released version 2.1.4 of its Fission audio editor, adding full support for OS X 10.9 Mavericks and moving to the 64-bit frontier for future performance gains. The update replaces the QuickTime engine for opening files with Rogue’s own internal libav for handling multimedia, which may not support some “extremely rare” file formats. The saving pipeline has been revamped, which improves how the Mac App Store version saves ringtones. The new version also improves its handling of extra-large AAC and Apple Lossless files, slims down the debugging window, and makes it possible to drag an iTunes song into the Mac App Store version with a single attempt.
