Fission from Rogue Ameoba is a simple audio editor. Very simple. There are no recording tools, no support for plugins, no compression or noise reduction and no equalisation tools. Will you miss those features? It really depends on what you need an audio editor for.
Fission is good for those who want to quickly convert between audio formats, or for those who already own Rogue Amoeba’s Audio Hijack Pro. Fission is available on its own or as part of a $50 bundle with Audio Hijack Pro – and that’s when it really begins to make sense.
You can open audio files in AIF, AAC, MP3, Apple Lossless or WAV formats. And here’s the killer feature. Editing is lossless – there’s no re-encoding when you save. When you edit a file, you edit it in its native format. So if you save back to MP3 you won’t be adding any new compression artefacts. Clever.
Fission enables you to split or join audio files, apply fades or introduce areas of silence. In short, it’s ideal for chopping up digital recordings of vinyl albums or editing down long portions of audio into short tracks. When you’re done, you can save to the original format or use QuickTime export tools to convert the file.
We were taken with Fission’s good looks and ease of use. It’s a fast and compact tool for quick editing, ideal for jobs where GarageBand or Audacity are overkill.
