Ratings and Reviews
Excruciating editing, pops and clicks everywhere.
I regret spending real money on this software.
Selections and markers snap to .02s. Can’t position them accurately enough to find zero-crossings. This is a HUGE PROBLEM, since it doesn’t make any effort to place them near zero-crossings (or put in tiny fades) to eliminate pops. Every cut has a pop. Garbage. (I downloaded the trial version from their website, but that one puts long fade-ins on all the exported files, so I didn’t notice the pops until I’d paid.)
Shows stereo files as mono. Can’t tell if one of your channels is going to pop until you export.
No accuracy or sample editing to remove pops. Not enough accuracy to create a short enough fade.
No way to add markers at the beginning and end of a selection. Very frustrating, since you can drag the ends of a selection independently with good accuracy, but then can’t mark them. (There is “remove and split”, which is the exact opposite.)
Fundamentally broken, very disappointing, and certainly not worth $28.99 for export files that pop and click.
Two stars because it looks pretty, and has some good ideas about approaching the problem of slicing up a big file.
It doesn't join files
My money wasted. I needed to join 3 mp3 files into one. Doesn't do the job, I am so sorry I bought it.
Exclusive and Lossless Editing with Excellent Technical Support
Fission’s ability to edit and save sound documents with lossless results makes this application one of a kind. Even my technical issue was solved the same day I reported it. I’m pleased with this application, my purchase, and the software development team behind it. I hope they continue to grow this useful application.
