If you need to convert formats, Fission can do that too, with simple export or batch conversion to the MP3, AAC, Apple Lossless, FLAC, AIFF, and WAV formats.

What's New

New in 2.2.4

* A crash was introduced in version 2.2.3, which could occur when importing a file. We've fixed this problem, so import away!

* Speaking of importing, the engine for it has been fully updated to ffmpeg 2.6.2. Nifty!

* Previously, certain FLAC files could cause Fission to crash. We did not like this, so we decided to squash that bug.

* An issue where some MP4 files wouldn't open correctly has also been rectified.

* Other minor fixes and improvements have been made.
